1.3 Notes on Usage In the use of YX8000 series inverter, please pay attention to the following points：

1. Constant torque low speed running

When the inverter outputs to a common motor at low speed for a long term, the output rated torque should be

derated due to the worsening radiating effect. If low speed constant torque long term running is required, then a

special variable frequency motor is needed.

2. Confirm motor’s insulation

Before usingYX8000 series inverter, please confirm the motor is insulated; otherwise, the equipment may be

damaged. Please confirm motor’s insulation termly when motor is working under bad condition.

3. Negative torque load

To some application situation such as lifting load, negative torque load may occur. Braking unit and resistor should

be connected with inverter, or over current or over voltage fault may happen.

4. The mechanical resonance point of load

The inverter may encounter the mechanical resonance point of load within certain output frequency range. Jump

frequencies have to be set to avoid it.

5. Capacitor and varistor

Because the inverter outputs PWM pulse wave, capacitor and varistor should not be connected with the output

terminals of the inverter, or the inverter may trip or components may be damaged,as shown in Fig.1-3.

Fig. 1-3 Capacitor connection with inverter output prohibited

6. Motor derating

When basic frequency is set to be lower than rated frequency, motor derating is necessary in order to avoid motor

overheating.

7. Running at frequency above 50Hz

If running at frequency above 50Hz, besides the increment of vibration and noise, the ranges of running speed of

motor shaft and mechanical device have to be guaranteed. Be sure to make an enquiry first.

8. The electro-thermal protective value of motor

If the applicable motor is selected as per requirements, the inverter can perform the thermal protection to the motor.

If the ratings of applied motor are not in compliance with the inverter, be sure to adjust the protective value to

guarantee the safe running of motor.

9. Altitude and derating

When the altitude is higher than 1000m, the cooling effect of inverter is deteriorated because of the rareness of air,

derating must be considered.


- 7 -

Fig.1-4 indicates the relationship between the altitude and rated current of frequency inverter.

10. On the level of protection

YX8000 Inverter protection grade IP20 is in the selection of state display unit or the keyboard case reach.

1.4 Notes Regarding Disposal When you dispose frequency inverter, pay attention to:

The capacitors in the main circuits may explode when they are burned. Poisonous gas may be generated when

front panel is burned.

Please dispose the inverter as industrial rubbish.

3.6.2 Main loop inverter side connection 3.6.2.1 DC reactor There is built-in dc reactor in the whole series of YX8000 inverter(18.5～90kw). DC reactor can improve the

power factor, can avoid the access of the high-capacity transformer and destroy rectifer bridge by the excessive inputted currrent, can avoid the grid voltage mutation or harm to dc circuit caused by the phase harmonic load.

3.6.2.2 Brake unit and brake resistor For YX8000 inverter under 15kw, brake unit is built in. In order to release the energy in braking runtime,

braking resistor must be connected in P+,PB end. Braking resistor wiring length should be less than 5m. Braking resistor temperature will be increased because of the release of energy, when installing the braking

resistor should pay attention to safety protection and good ventilation. YX8000 inverter above 18.5kw require external braking unit. In order to release the energy in braking

runtime braking resistor must be connected in P+,PB end. The connection length between Inverter P +, P-end and brake unit P +, P-end should be less than 5 m. The

wiring length between brake unit P +, PB and braking resistor P +, PB end should be less than 10 m. Note：Don’t reverse the polarity of P+，P-；P+，P - end are not allowed to directly connect braking

resistor, otherwise it will damage the inverter or fire hazards. 3.6.3 Main loop motor side connection

3.6.3.1 Output reactor

When the distance between the inverter and motor exceeds 50m，overcurrent protection can easily occur due

to large current leakage caused by parasitic capacitance effect of long cable to ground.At the same time in order

to avoid the motor insulation damage,output reactor are needed for compensation.

3.7 EMC Installation Instruction Inverter outputs PWM wave, it will produce electromagnetic noise.To reduce the interference, EMC

installation will be introduced in this section from noise suppression, wire connection,grounding, leakage current

and filter of power supply

3.7.1 Noise Suppression

(1) Noise Type

Noise is unavoidable during inverter operation.Its influence over peripheral equipment is related to the noise

type,transmission means, as well as the design, installation,wiring and grounding of the driving system

(2) Noise Suppression Methods

Path Noise suppression methods

②

If closed loop is formed between the peripheral equipment and the inverter wiring, the grounding leakage

of the inverter will make the equipment operation error.

Solution: Remove the grounding of the peripheral equipment.

③

When peripheral equipment share the same power source with the inverter, the noise transmitted through

the power line may make the equipment operation error.

Solution: Mount a noise filter at inverter side, or isolate the peripheral equipment with an isolated


- 22 -

transformer or power filter.

④⑤⑥

Electronic equipment such as computers, measuring meters, sensors and radio equipment, when in the

same cabinet with inerter, with their wiring close to the inverter, may lead to operation error due to radio

interference.

Solution:（1）The susceptible equipment and its signal lines should be kept away from the inverter. Use

shielded cable for the signal line. Ground the shielding coat. Protect the signal cable with a metal pipe

and keep it off the inverter input/output cable. When crossing of the signal line and the inverter

input/output cables is inevitable, make sure it is orthogonal.

（2）mount radio noise filter or linear noise filter (choke coil) to the input/output side of the inverter t

suppress the radio noise.

（3）The shielding coat for the cable connecting inverter and the motor should be thick. The wiring can

be arranged through thick pipe (2mm or thicker) or cement trench. The cable should be through a metal

pipe, and has its shielding coat grounded. You may use the 4-core cable as the motor power cable.

Ground one core at inverter side, with the other end of it connected to the motor case.

①⑦⑧

When the signal cables are parallel to, or bound together with the power cables, the static and

electromagnetic induction will cause the noise transmit through the signal cable, thus affecting the

related equipment.

Solution: (1) Avoid laying the signal cable parallel to the power cable, or bind them together. (2) Keep the

susceptible peripheral equipment away from the inverter. (3)Keep the susceptible signal far away from

the input/output cables of inverter. Shielded cables should be used as the signal or power cable. Let them

trough metal pipes respectively would achieve better effect. The metal pipes should be at least 20cm

away from each other.

Table3-3 Noise suppression method

3.7.2 Wiring Connection and Grounding

(1) Please try not to wire motor cable (from inverter to motor) in parallel with power cable and keep at least 30cm from each other .

(2) Please try to arrange the motor cable through Control signal cable metal pipe or in metal wiring groove. Fig. 3-20 Orthogonal wiring

(3) Please use shielded cables control signal cable, and connect the shielding coat to PE terminal of inverter with proximal grounding to inverter.

(4) PE grouding cable should be directly connected to the earth plate. (5) The control signal cable should not be in parallel with strong electricity cable(power cable/motor cable).They

should not be bent together and should be kept away at least 20cm from each other. If cable crossing is inevitable, please make sure it is orthogonal as Fig.3-20

(6) Please ground the control signal cable separately with power cable/motor cable. (7) Please don’t connect other devices to inverter power input terminals(R/S/T ).

This function is mainly used to improve noise as motor running and problems like interference of frequency converter to the outside world.

Advantages of high carrier frequency：the current wave is ideal with less current harmonics and small noise. Disadvantage of high carrier frequency：larger switch loss，larger temperature rise，the output capacity of the

frequency inverter is influenced and it should be derated with high carrier frequency; in the mean time, the leakage current increases and the extral electromagnetic interference is reinforced.

It is contrary to the above situation with low carrier frequency. If the carrier frequency is too low,that will result in instability in the low-frequency operation，the decrease of torque and even oscillation.

The carrier freq. has been properly set before leaving the factory. In general, users do not need to modity theparameter.

6.6 PID closed loop parameters（P5 Group）

PID control is a common method used for process control.It’s used by doing Proportional, integral, differential calculation on the residual quantity between the feedback signal of controlled quatity and target signal, to adjust the output frequency of the inverter and to constitute the negative feedback system，so that the controlled quantity on the target volume is stable. It’s suitable for flow control, pressure control and temperature control.Basic control principle is shown in below figure.

0～5 0

When PID is chosen as the frequency source,namely 6 is chosen as P0.00,this function will work.The parameter determines the given channel of process PID.

Relative value is set to be the target volume of process PLD with the set 100% corresponding to 100% of the feedback signal in controlled system.

System is always operating according to the relative value（0～100.0%） Note：Multistage can be realized by setting parameters in PA group.


value

P5.01 Keypad Preset PID reference 0.0%～100.0% 0.0～100.0 0.0%

When choosing P5.00=0，the target source is keypad reference and therefore parameters need to be set. The reference value of this parameter is the feedback value of the system.

Note：a given channel can’t coincide with the feedback channel. Otherwise，PID can not effectively

value

P5.03 PID output characteristics selection

0： positive characteristic 1： negative characteristic 0～1 0

PID output is positive characteristic：When the feedback signal is greater than a PID reference，PID can only reach balance by decreasing output frequency, such as PID winding tension control

PID output is negative characteristic：When the feedback signal is greater than a PID reference，PID can only reach balance by increasing output frequency, such as PID unwinding tension control


value P5.04 Proportion gain（Kp） 0.00～100.00 0.00～100.00 1.00 P5.05 Integral time（Ti） 0.01～10.00s 0.01～10.00 0.10s P5.06 Differential time（Td） 0.00～10.00s 0.00～10.00 0.00s


- 60 -

Proportion gain（Kp）：It determines the regulation intension of the whole PID regulator. The higher P is，the greater adjust strength is.This parameter is represented by 100. When the deviation between PID feedback quantity and the given quantity is 100%, PID controller for adjusting the amplitude of the output frequency command is the maximum frequency（Ignore integral and differential effect）.

Integral time（Ti）：It determines the speed of integral regulating on the deviation between PID feedback quantity and the given quantity. The integration time is when the deviation between PID feedback quantity and the given quantity is 100%,Integral regulator continues adjusting as going though that time（Ignore the proportional and differential effective）and the adjustment amount reaches the max frequency (P0.04).The shorter integral time is, the greater adjust strength is.

Differential time（Td）：used to adjust the strength of the change rate of the deviation between PID feedback value and given value. Differential time refers that if the feedback value change 100% within the time, then the adjustment value of the differential regulator is the max frequency（P0.04）(proportional and differential effect is neglected)。The longer the differential time is, the larger the adjust strength is.

PID is the commonest control way in the process control and each part plays its own function. See the introduction of operating principle and adjusting method:

Proportional control（P）：if there is the deviation between the feedback and given value, the output and deviation are proportional adjustment. If the deviation is constant, then the adjustment value is constant. The proportional adjustment can response the feedback change quickly, but can not reach non-error control only by proportional adjustment. The more the proportional gain is, the faster the adjustment speed of the system is, but the excessive may cause vibration. The adjusting method: set a longer integral time set the differential time as 0,run the system only by the proportional adjustment and change the given value, then check the stable deviation (static error) between the feedback signal and given value. If the static error is in the change direction of the given value (such as increase of the given value, the feedback is always less than the given value under stable mode), the proportional gain is increasing, and on the contrary, the proportional gain is reducing. Repeat the above procedure till that it reaches lower static error( non-error is hard).

Integral time（I）：If there is deviation between the feedback and given value, the output adjustment is continuously increasing. If the deviation remains, proceed to increase the adjustment value till no deviation. The integral regulator can eliminate the static error effectively. Repeat overshoot may occur and the system is not stable till vibrating occurs if the integral regulator is too strong. Because the characteristics of the oscillation caused by excessive integral effect are: the feedback signal is around the given value and the amplitude increasing till the vibration, the parameter of the integral time is generally adjusted from up to down. During the process, monitor the effect of the system adjustment till the stable speed of the system satisfies the requirements.

Differential time（D）：If the deviation between the feedback and given value changes,the output and the change rate of deviation are proportional adjustment value, which is only relevant to the direction and the value of deviation change and is not relevant to the direction and value of the deviation. The function of differential adjustment is that it can adjust according to the change trend to control the change of the feedback signal. Please use the differential adjustment prudently because the integral regulator is easy to enlarge the interference of the system, especially for the interference of the higher changing frequency.

control 0.0～100.0% 0.0～100.0 0.0%

Sampling period（T）：refers to the sampling period of the feedback value and the regulator calculates once

in each sampling period. The longer the period is, the slower the response is. Limit deviation of PID control：refers to the permissive max deviation between PID output value and given

value of closed loop. As indicated in the figure below, PID regulator stops adjusting within the limit deviation. The proper setting of the function can adjust the precision and stability of PID system.

1：self study of parameter You must isolate the load to make the motor static before the paramter self-studying. You must input the correct nameplate of the motor（P8.01－P8.02）, otherwise the result of the parameter

self-study may be inaccurate. Prior to the parameter self-studying, you should set the ACC/DEC time（P0.10、P0.11），properly based on

the inertia of the motor, otherwise over-current or over-voltage may occur during the self-studying process. Set P8.00 to 1 and press DATA/ENTER， then the motor starts the parameter self-studying, with the LED

displaying “-FUN-”and flashing. Next press FWD to start up, then it displays “FUN-0”，and the motor starts to run as it displays “FUN-1”,with the“RUN/TUNE”light flashing.As self-study ends, it displays “-END-”.At last it lacks to the stop mode interface. Press MENU/ESC and exit from parameter self-studying mode when the “-TUN-“ flashing.

You may press STOP/RST to stop the operation during self-studying process .Note: Keyboard control is the only way to control the start-up or stop of self-study; then the functional code recovers to zero after the self-study.

2：Static parameter self-study It is unnecessary to isolate the load from the motor during the static parameter self-study. Prior to the

parameter self-study, you must input the correct nameplate parameter（P8.01－P8.02）.After the self-study, it can detect the stator resistance, rotor resistance and the leakage inductance of motor, while it can not detect the mutual inductance of the motor and non-load current. The user may input the corresponding values based on your experience.

Note：Please set the above parameters according to the nameplate of the motor. The fine control performance of vector control requires accurate motor parameters.

YX8000 series frequency inverter provides self-studying function.The self-study of precise parameters comes from the accurate setting of motor nameplate.

Please ensure that the power of the frequency inverter matches with power of the motor in order to guarantee the control performance. If the display is large, the control performance of the frequency inverter reduced obviously.

Note：It’s possible to initialize the parameters P8.02～ P8.08 by resetting the rated power of the motor（P8.01）.

The above parameters are only applicable to vector control mode and invalid for V/F control.Under shifting frequency 1（P9.02）,the speed loop PI parameter is：P9.00 and P9.01.If the shifting frequency is over 2（P9.05）,the speed loop PI parameters are：P9.03 and P9.04. And between them, PI parameters are obtained from the linear change of the two groups. See the figure below:

Fig.6-26 Diagram of PI parameters The speed cycle dynamic response characteristics of the vector control can be adjusted by setting the

proportion coefficient and integral time of the speed regulator.The dynamic response of speed cycle can be sped up either by the increase of proportion gain or reducing of the integral time, but it is easy to cause system oscillation over-strike either by higher proportion gain or less integral time. Smaller proportion gain is also easy to cause stable oscillation in the system and speed static error may occur.

Speed loop PI parameters have a lot to do with the inertia of the system, so adjust it to satisfy kinds of demands based on the default PI parameters to different load characteristics.

0：No protection There is no overload protection characteristics for motor (be cautious).

1：Ordinary motors（（With low speed compensation）Since ordinary motor cooling effect at low speed is poor, Corresponding electronic thermal protection value is also adjusted properly. The low speed compensation characteristic mentioned here refers to the de-rating of overload protection valve value in motors whose running freq. is under 30Hz.

2：Variable frequency motor（Without low speed compensation）The protection value doesn’t need to be adjusted during low-speed operation because the heat dissipation of the variable frequency motor is not affected by the rotate speed.

If the descend rate of the frequency upon momentary power-fail is 0, this function is invalid. Lower freq. point upon momentary power-fail：when the bus voltage descends to the lower frequency point

upon momentary power-fail after the power-fail, the frequency inverter starts to lower the running frequency according to the descend rate（PA.03）of frequency upon power-fail to make the motor under power generation mode so that the feedback power can remain the bus voltage to ensure the normal operation of the frequency inverter until the next power-on.

During the deceleration running of the frequency inverter, the actual descent rate of the motor speed may be lower than the descend rate of output frequency because of the influence of load inertia.Then the motor feedbacks power to the frequency inverter to increase the bus voltage. It may cause the increase of bus voltage to lead the overvoltage error of the frequency inverter if no any action.

Overvoltage stalling protection: under operation of the frequency inverter, the system detects the bus voltage and compares it with overvoltage stalling point defined by PA.05（corresponding to standard bus voltage）.If it surpasses the overvoltage stalling point, the output frequency of the frequency inverter stops descending and then proceeds to descend until it is detected that the bus voltage is lower than the overvoltage stalling point.

Under the operation mode, if the frequency inverter loads too much, the actual increasing rate of the motor speed is lower than the increasing rate output frequency. It may cause acceleration over-current error and lead the fault of the frequency converter if no any action.

The auto current-limiting function can detect the output current under operation mode of the frequency inverter and compare it with the current-limiting point defined by PA.07. If it surpasses the current-limiting point, the output frequency of the frequency inverter lowers according to the descend rate（PA.08）of over-current frequency. And it recovers the normal operation when it is detected that the output current is lower than current-limiting point. See the figure below:

If the load speed is greater than the preset upper limit frequency, the output frequency is limited and the output torque will be different from the preset value.Under torque control, the torque set by PC.08 is torque command.If the torque command is set by keypad（PC.08 is 0），torque command can be obtained by setting PC.09. When the torque is set as a negative number, The motor will reverse.

The torque control and speed control can be shifted by multifunctional input terminal. If the preset torque is greater than the load torque, the output frequency of the frequency inverter will increase.

7.2 The common failures and its treatment

Frequency converter may encounter the following fault conditions in the course running, please refer to the

following simple method for fault analysis:

Power on without display:

Check if the input power is in line with rated voltage by multimeter. If you have any questions please check

the power supply and rule out.

Check whether the three-phase rectifier bridge is in good condition. If the rectifier bridge has blasted, please

seek service.

Check whether the CHARGE lamp is light. If the light has gone, fault generally focus on the rectifier bridge

or buffer resistance. If the light is on, the fault may be on switch power supply.Please seek service.

Power air switch tripping after power on:

Check whether there is power grounding or short circuit conditions and eliminate the existing problems.

Check to see if the rectifier bridge has been broken down, if damaged, seek service.

The motor fails to rotate after frequency inverter running:

Check whether there is a balanced three-phase output among U, V, W. If there is, lines or damage itself, the

motor or motor blocked due to mechanical trouble.Please rule out.

If there is output but three-phase imbalance, it should be that inverter drive board or output module is damaged,

please seek service. If due to stops up transfers, Please rule out.

If there is no output voltage, output module and drive board might be damaged. Please seek service.

inverter showing normal as power on and Power air switch tripping after running:

See if there are any short circuit between the output module and condition.If yes, please seek service.

Check whether there is a short circuit or ground between motor lead.If yes, Please rule out.

If trip occasionally and there is a relatively far distance between motor and frequency converter, consider to

add the output AC reactor.

Attention

(1) Reset the inverter after throughly investigating the cause of fault and clearing, otherwise, the inverter may be

damaged.

(2) If it can’t be reseted or fault occurs again after reset, please check the cause of fault, continuous reset may

damage inverter.

(3) Reset the inverter after waiting for 5min when overload or overheat protection occurs.

Chapter 9 Serial Port Communication Protocol Of

RS485

9.1 Communication overview Our YX8000 series of inverters provide users with a common industrial control RS485 communication

interface, in which the MODBUS standard protocol is used for communication. The inverters can be used as slave

connected to the host (such as PLC controller, PC), both of which have the same communication interface and

protocol, for the purpose of centralized monitoring of the inverters. Or one inverter can be used as host and other

inverters as slaves, all connected with RS485 communication interface, to achieve multi-machine interaction of the

inverters. And with this communication interface, a Keyboard can also be connected to inverters for remote

operation.

The MODBUS communication protocol of the inverter supports two transmitting ways: RTU mode and ASCII,

and either can be chosen. The following is a detailed description of the communication protocol of the inverter.

9.2 Communication protocol specification 9.2.1 Communications networking methods

(1) networking methods with inverter as slave:

Fig. 9－1 networking of slaves

(2) The networking of multi-machine interaction：

Fig.9—2 The networking of multi-machine interaction

9.2.2 Communication protocol

The inverter can either used as a host or slave in RS485 network. It can be used for controlling our other inverters as host to achieve multi-level linkage, or controlled by host (PC or PLC) as a slave. The specific communication mode as follows:

a) inverter is used as slave, in point-to-point communication of master-slave mode. Host sends commands from broadcast address, while slave doesn’t answer.

b) inverter is used as host, sending commands from broadcast address, while slave doesn’t answer. c) The address, baud rate and data format of the inverter can be setup by using the keyboard or the serial

communication. d) message of error is reported by slave, in the recent response frame against host polling.

9.2.3 Communication Interface

The communication is using RS485 interface, with asynchronous serial and half-duplex transmission. The

default communication protocol in ASCII mode.

The default data format: 1 start bit, 7 data bits, 2 stop bits.

The default rate is 9600bps. Communication parameter settings reference P3.09 ~ P3.12 function code. 9.3 Contents

MODBUS Serial Protocol defines the content and application form if the frame of asynchronous transmission in serial communication, including: host polling and broadcast frame, the response frame form of slaves; the frame content organized by the host includes: slave address( or broadcast address), command execution, data and error check etc. The response of slave adopts the same structure including: action confirmation, returning data and error check. If there is any error when the slave is receiving frame or can not accomplish the action, required by host, it will organize an error frame to feed backed to the host.

9.4 Application mode YX8000 series frequency Inverters can access the “unit-host and multi-slave” control network with

RS232/RS485 bus. 9.5 Bus structure

(1) Interface RS485 hardware interface

(2) Transmission mode Asynchronous serial and semi-duplex, only the host or slave can send and the other can receive the data

simultaneously. During the serial asychronous communication, the data is transmitted frame by frame in the form of message.

(3) Topology structure Uni-host and multi-slave system. Set the slave address between 1-24 and 0 is the broadcast communication

address. The address of each slave in the network is unique, which is the foundation to ensure MODBUS serial communication. 9.6 Protocol Specification

The protocol of the series of frequency converters is an asynchronous serial master-slave protocol and only one unit (the host) can build the protocol (called “inquiry/command”). Other equipments (slaves) only can respond to the “inquiry/command” by providing data, or take actions according to the “inquiry/command” of the host. The host here refers to the PC, industrial control device, or programmable logic controller (PLC) etc. Slave refers to the series of frequency inveters or other control devices with similar protocol. The host can communicate with a single slave or send broadcast information all slaves. The slave should respond a message (response) to single “inquiry/command” of the host. And for the broadcast information, the slaves need not respond the information to the host. 9.7 Frame structure

The communication data of the MODBUS protocol of the series of YX8000 series frequency ivnerters has two forms,RTU (Remote Control Unit) and ASCII (American Standard Code for Information International interchange).

See the form of each byte in RTU mode below: Coding system: 8-bit binary system, in each 8-bit frame field, there are two hex characters, hex 0-9,A-F. See the form of each byte in ASCII mode below: Coding system: the protocol is hex. The meaning of ASCII information: “0”~ “9”. “A” ~ “F” each hex is indicated by corresponding character information in ASCII.

Character ‘0’ ‘1’ ‘2’ ‘3’ ‘4’ ‘5’ ‘6’ ‘7’ ‘8’ ‘9’

The bit of bytes including: start bit, 7/8 data bit, check bit and stop bit. See the description of bytes bit below: 11-bit character frame:

10-bit character frame

Start bit Bit1 Bit2 Bit3 Bit4 Bit5 Bit6 Bit7

No parity bit Even parity bit Odd parity bit

Stop bit

In RTU mode, new frame usually starts at the transmission time of at least 3.5 bytes. The transmission time of 3.5 bytes can be easily controlled on the internet whose transmission speed is calculated by baud rate. And then the date fields are in order: slave address, operation command code, data and CRC check word, the transmission byte in each field is hex 0…9, A…F , the internet always is monitoring the activity of the communication bus. Each internet device will confirm the byte as receive the first field (address information). As the last byte finished, an interval occurs between it and a similar transmission time of 3.5 byte to indicate the end of the frame. After that, a new frame will be transmitted.

The information of a frame must be transmitted by a continuous data flow. If there is ainterval over 1.5 bytes

prior to the end of the transmission, the receiver will clear the incomplete information and mistakes the last byte for the address of a new frame. Similarly, if the interval between the start of a new frame and the previous frame is less than 3.5 bytes, the receiver mistakes it for the continuing of the previous one. So the mistake of frame finally cause incorrect CRC test value and communicaiton error.

Frame END T1-T2-T3-T4（Transmission time of 3.5 bytes）

In ASCII mode, the frame start is “:” (0x3A) and the END default is “ CRLF” （“0x0D””0x0A”）. In ASCII mode,all the data bytes are transmitted by ASCII code except the frame start and end: sending high 4-bit byte first and then sending low 4-bit byte. The data is 8-bit in length under ASCII mode. For ‘A’～‘F’, the capital letter of ASCII is adopted. Then the data is tested by LRC check which covering from the slave address to the data information. The checksum is the complement code of bytes sum ( the carry bit is neglected) all data involved in the check.

The error verification mode of the frame mainly includes the verifications of two parts: i.e，bit check of the byte ( even/ odd parity check) and the whole data check of the frame (CRC check or LRC check). 9.8.3.1 Byte bit check

The user can elect different check mode or no check as required, which may influence the verfication bit place of each byte.

The meaning of even parity check: add an even parity bit prior to the data transmission used to indicate that the number of “1” in the data is odd or even. The check bit is 0 if it is even, “1” for the odd. It is used to remain the parity of the data.

The meaning of odd parity check: add an odd parity bit prior to the data transmission used to indicate that the number of “1” in the data is odd or even. The check bit is 0 if it is odd, “1” for the even. It is used to remain the parity of the data.

For instance, if you want to transmit “11001110”. There are 5 “1”, the even parity bit is “1” if use even parity check ,while the odd parity bit is “0” if use odd parity check. The parity check bit is put in the place if the check bit of the frame during data transmission, then the receiver also needs parity check. If the parity of the received data is inconsistent with the preset one, communication error occurred. 9.8.3.2 CRC (Cyclical Redundancy Check)

Using RTU form, the frame contains frame error detection based on CRC algorithm. CRC detected all the content of the frame. CRC contains two bytes and 16-bit binary value. It is added into the frame after calculated by the transmission device. The receiver will calculate the CRC of the frame it received and compare it with the one it received. Transmission error occurs of the two CRC values are not equivalent.

CRC is saved to 0xFFFF firstly, and then use a continuous over 6-bit byte to process the present value in the register. Then only 8-bit data in each character is valid to CRC while the start bit, end bit and parity check bit are invalid.

During the CRC production, each 8-bit character is individually different or （XOR）from the content in the register, and the result moves toward the lowest effective bit while the highest effective bit is filled with 0. LSB is picked up to detect. If LSB is 1, the individual value in the register is different from the preset one;if LSB is 0, no this performance. The whole process needs to be repeated for 8 times. As the last bit (8th bit) finished, the next 8-bit is individually differrent from the preset value in the register. At last, the value in the register is the CRC value after the performance of all bytes.

The algorithm of CRC adopts the international standard CRC check rule. The user may refer to the relevant CRC algorithm to edit the proper CRC algorithm as required when editing the CRC algorithm.

Here provides a simple function of CRC for your reference ( C-language programming): Unsigned int crc_cal_value(unsigned char “data_value, unsigned char data_lengty)

int i; unsigned int crc_value=0xffff; while(data_length--)

crc_value^=*data_value++;

for(i=0;i<8;i++)

if(crc_value&0x0001)crc_value=(crc_value>>1)^0xa001; else crc_value=crc_value>>1; return(crc_value);

In the stair logic, CKSM calculates CRC value accoridng to the frame content by LUT which is simple and


- 90 -

fast, but needs larger ROM space, so please be prudent to use in the environment where the space is required. 9.8.3.3 ASCII mode check (LRC check)

LRC check is the accumulated value from ADDRESS to DATA CONTENT, such as the above check code in 11.6.2: 0×02×0×06+0×00+0×08+0×13+0×88+0×AB, and then select the compliment of 2=0×55. 9.8.4 Definition of data addr.

This part is the definition of the communication data addr. Which is used to control the operation of the frequency converter and obtain the state information and the relevant parameter setting etc.

(1) Indicating rules of the parameter addr. With the functional code, but it needs to be conveted to hex. If the code of H5.05 is 58, the hex indication of

the functional addr. Is 003AH. The scopes of high and low byte are: high-bit-00~01; low-bit byte——00~FF. Note: PE Group: the parameters set by the manufacturer, so they are unreadable or unchangeable; some

parameters cannot be modified when the frequency converter is under operation; some parameters never can be modified in any state; the setting scope, unit and relevant instructions should be noted if you want to change the functional code.

In addition, because EEPROM is saved frequently, it may decrease the service life if EEPROM. For users, some functional codes are unnecessary to save under communication mode and just need to modify the value in RAM to satisfy the application requirements. You can achieve the function only by changing 0 in the highest bit of the functional code to 1. For instance, the functional code H0.07; the address can only be used write in RAM, but without read function, i.e. it is invalid address for read.

0004H：error

R

Address of communication setting value

2000H

The communication setting value scope（-10000～10000）

Note： the communication setting value is the relative percentage（-100.00%～100.00%），and can be used for write action.When set it as the frequency source, the corresponding value is the percentage of the max frequency（P0.04）；when it is used as the PID given or feedback value,the corresponding value is the percentage of PID. Among them, both PID given and feedback value are calculated in the form of percantage

9.8.5 Extraneous response of error information

When communication is connected and an error comes into being, now the inverter will respond error code

to the host control system in a fixed format of response.No matter is the command code of inverter communication

is “03”or“06”，the command byte of fault response replies host control system according to “06”and the data

address is fixed 0x5001.

For example：

RTU Slave fault response message

START T1-T2-T3-T4（Transmission time of 3.5 bytes） ADDR 01H CMD 06H HIGH BIT OF FAULT RETRUN ADDR

50H

LOW BIT OF FAULT RETURN ADDR

01H

HIGH BIT OF ERROR CODE 00H LOW BIT OF ERROR CODE 05H LOW BIT OF CRC CHK 09H HIGH BIT OF CRC CHK 09H END T1-T2-T3-T4（ Transmission time of 3.5 bytes ）


- 92 -

ASCII Slave fault response message

START ‘:’ ‘0’

ADDR ‘1’ ‘0’

CMD ‘6’ ‘5’ HIGH BIT OF FAULT RETRUN ADDR ‘0’ ‘0’ LOW BIT OF FAULT RETURN ADDR ‘1’ ‘0’ HIGH BIT OF ERROR CODE ‘0’ ‘0’ LOW BIT OF ERROR CODE ‘5’

LRC CHK Hi ‘A’ LRC CHK Lo ‘3’

END Lo CR END Hi LF

Meaning of error code:

Error code Instruction 1 Password error 2 Command code error 3 CRC ECC error

4 Illegal address 5 Illegal data

6 Null paramter change

7 System locked 8 Freq. inverter is busy（EEPROM is storaging）
