1.0 Safety

1.1 Warnings

do not perform any measurements on the frequency converter when the frequency

converter is connected to the mains Do not perform any voltage withstand test on any part of the Vacon NXP. There is a certain

procedure according to which the test shall be performed. Ignoring this procedure may

result in damaged product.

The Earth leakage current of the Vacon NXP frequency converter exceeds 3.5 milliamps A/C

and in compliance with EN61800 -- 5 -- 1 a reinforced protective ground connection is used

and should not be removed from the drive.

Only Vacon spare parts should be used.

Do not touch the components on the circuit boards static voltage discharge may damage the

components.

1.2 Safety Instructions

The components of the power unit of the frequency converter are live when the Vacon NXP

is connected to the mains potential. Coming into contact with this voltage is extremely

dangerous and may cause death or severe injury. The control unit is isolated from

mains potential.

The motor terminals U, V, W and the DC link/brake resistor terminals are live when the

Vacon NXP is connected to the mains, even when the motor is not running. After disconnecting the frequency converter from the mains, wait until the fan stops and the

indicators on the keypad go out (if no keypad is attached, there are indicators on the cover).

Wait 5 minutes more before doing any work on the Vacon NXP connections. Do not even

open the cover before this time has expired.

The control I/O terminals are isolated from the mains potential. However, the relay outputs

and other I/O terminals may have a dangerous control voltage present even when the Vacon

NXP is disconnected from the mains. Always check the drawings to see if any of the relays or

the I/O is connected to a dangerous potential.

Before connecting the frequency converter/control system to the mains make sure that the

Vacon NXP front cable covers are closed.

The Earth for protection inside the frequency converter protects only the converter itself

against a fault in the motor or the motor cable. It is not intended for personal safety.

1.3 Warning symbols

For your own safety please pay special attention to instructions marked with the following symbols:

2.0 Introduction

The Vacon NXP is a state-of-the-art A/C drive for use in the lift applications were reliability, dynamic

performance, precision and power are required.

The ride quality and reliability of the lift system is in most cases the result of precise dynamic controlof the motor. The Vacon NXP has been designed to provide the best possible control under all

circumstances, ensuring high operational reliability and ride quality for the entire lifetime of the

system.

As a forerunner in designing and manufacturing A/C drive systems, Vacon has developed many

innovative solutions and leading-edge technology for demanding applications one of which is the lift

application. The Vacon Drive has been used on many lift applications both within the UK and abroad.

The Vacon NXP is suitable for both asynchronous and PM motors and is also suitable for both geared

and gearless applications. The control topology is both open loop sensorless flux vector and with

encoder feedback closed loop flux vector control. The drive utilises the latest PWM technology to

ensure switching losses and efficiencies to the motor are minimised and maximised respectively.

The Vacon NXP also has the advantage of including all the filters and DC chokes incorporated within

the Power module to ensure compliance with the EMC directive. The Vacon unit can also have an

optional regenerative low harmonic drive added to improve power quality and have additional

energy saving’s when the lift is in the regenerative state.

3.0 EMC considerations

Variable frequency variable voltage drives utilise high-power electronic switching to control both the

frequency and the voltage to the motor, this has a side effect of causing electromagnetic

interference and the Vacon NXP complies with the relevant EMC standards. This compliance relies

on the correct installation requirements being followed. The following is required to keep

conformance to the relevant standards:

Wire the mains to the control panel in a suitably rated SY mains cable, with the screen

connected at both the isolator and the panel earthing points. Ensure the screen is bonded

using 360° clamps or ensure the screen pigtail is less than 50 mm long.

Wire the motor from the panel connections in a suitably rated SY mains cable with the

screen connected at both the panel and the motor earthing points. Ensure the screen is

bonded using 360° clamps or ensure the screen pigtail is less than 50 mm long. Ensure the motor and mains cable are at least 300 mm apart. Also ensure that any other

cable such as Brake thermistor and encoder wiring is kept separate from the motor cables.

Ensure the encoder cable's screen cables are not the only at the drive. Ensure the cable is

properly terminates using the strap provided in the drive.

Ensure the earthing of the incoming mains is a good Earth and is in compliance with the

current IEEE regulations. (Note: the earthing should not solely rely on trunking and conduit

connections or bonding strips).

Ensure the Earth is connected from the isolator to the panel via the recommended practices

in the current IEEE regulations.

4.0 Block diagram of the drive

The figure below presents the block diagram of the Vacon NXP frequency converter. The frequency

converter mechanically consists of 2 units, the power unit and the control unit.

The three-phase A/C choke (1) and the mains end together with the DC link capacitors (2) forms a LC

filter which, again, together with the diode bridge produces a DC voltage that is applied to the IGBT

inverter bridge (3) block. The A/C choke also functions as a filter against high-frequency disturbances

from the mains as well as against those caused by the frequency converter to the mains. It, in

addition, enhances the waveform of the input current to the frequency converter. The entire power

drawn by the frequency converter from the mains is active power.

The motor and application control block is based on the microprocessor software. The

microprocessor controls the motor based on the information received through measurements,

parameter settings, control I/O and the control keypad. The motor application control block controlsthe motor control ASIC which in turn calculates the IGBT switch positions. Gate Drivers amplify these

signals, and operates the drives IGBT inverter bridge.

The brake chopper is an additional unit built within the drive system to control the voltage across

the DC link when the motor enters the regenerative state. The excess energy is placed across the

resistors to maintain the DC link at the correct voltage.

Keypad layout



12

6.2 Navigation of the control keypad

The data from the control keypad is arranged in menus and submenus. The menus are used for the

displaying of monitored items such as frequency, current, voltage, etc and also the displaying and

editing of the parameters used to configure the drive.

The various different functions of the drive are arranged in a simple menu structure of a main menu

consisting of 7 menus as follows:

M1 Monitor.

M2 Parameters.

M3 Keypad control.

M4 Active faults.

M5 Fault history.

M6 System menu.

M7 Expander boards (option cards).

Each of the various submenus can then be accessed from the main menu for example to access the

monitoring values you first access the monitor menu and then using the right arrow enter the

monitor menu and using the up and down arrows you can then access each of the monitoring values

as shown below:

Another example is if you want to change a parameter you first access the parameter menu once

again press the right arrow to access the submenu’s and then use the up and down arrows to scrollto the submenu you require and then use the right and left arrow to enter/exit the submenu. Once

in the submenu the value of the parameter can be changed by pressing the right arrow which causes

the parameter to flash, using the up and down arrow the value can be changed, once the correct

value is displayed this is confirmed by pressing the enter button as shown in example below:

! Tech TIP: for quicker adjustment once the parameter is flashing the right arrow can be pressed again and using the left arrow and

right arrow select the digit of the parameter which can using the up and down arrows individually adjusted.

25 Microprocessor

Watchdog fault

The microprocessor has a monitoring circuit to check the programme

is running correctly. When the program does not run correctly the

system faults with the Watchdog error.The possible causes could be:

- faulty operation due to interference

- faulty component in the drive

29 Thermistor fault Not used

37 Device change This occurs on switch on when an option board has been changed.

Press reset and the drive should not re-fault. If a Fault re-occurs,

check the option card has been fitted correctly and in the correct

slot.38 Device added This occurs when an option card has been fitted. Press reset and the

drive should not re-fault. If a fault re-occurs, Check the option card

has been fitted correctly and in the correct slot.

39 Device removed This occurs when an option card has been removed.

40 Device unknown This occurs when an option board is placed in the wrong slot or the

option board or main control card is damaged.

41 IGBT temperature This occurs when there is localised heating in the IGBT, this can occur

when the motor is overloaded or there is an instantaneous increase

in the motor current. This can also occur when there is a component

failure. Leave the drive to cool down and reset the drive. If this fault

re-occurs, check items as in the over-current fault. If this fault doesnot clear contact the factory.

43 Encoder fault This fault can occur due to several reasons, and is caused by loss of

feedback from the motor encoder.

The possible causes could be:

- The encoder supply is disconnected.

- The motor is not moving, check brake to lift.

- The encoder signals are connected incorrectly.

- The encoder signals are reversed, check parameter encoder

direction in the expander board parameters. Change if

necessary.

- Perform an auto tune.- Also check the following sub code for indication of the fault.

1 = encoder Channel A is missing.

2 = encoder Channel be is missing.

3 = both encoder channels are missing.

4 = encoder reversed.

5 = encoder board missing.

! Tech Tip: To check the encoder signals first check the supply voltage on the

encoder board on terminals 9 and 10 is the correct supply (place the meter on

DC). Then with the negative probe of the meter on 9, run the lift on open loop

and each of the encoder signals should be approximately half of the supply

voltage when the lift is running.

8.0 Commissioning an Asynchronous (standard motor) Machine

8.1 Initial parameter settings and checks

At Digital Advanced Control, we always try to set the optimum parameters for the drive to be run

with the minimal of adjustments. This is dependent on the information given to us whenmanufacturing the control panel. It is important that the following checks are carried out to ensure

the information given was correct and your parameter settings are set correctly within the drive to

suit site conditions.

Before switch on check the following:

1. Write down the following from the motor data plate.

a. The motor nominal current Amps.

b. The motor nominal voltage Volts.

c. The motor nominal frequency Hz.

d. The motor Cos Phi Θ Θ.

e. The motor nominal RPM RPM.

2. Check the motor is connected correctly on the high-speed winding and the connections are

securely fastened.

3. Ensure the brake, thermistors (if fitted), motor fan (if fitted) and encoder (if fitted) are all

connected correctly and are securely fastened.

4. Check the encoder voltage and check the link on the encoder card is set for the correct

voltage.

5. Ensure the control system is on inspection control and is capable of being run up and down

safely. Ensure your personal safety, once you are happy everything is safe switch the lifton.

6. In the motor parameters enter the data recorded above. Set the motor current limit to

2xFLC of the motor.

7. Set the following motor parameters:

a. P2.2.1 nominal linear speed = (synchronous/motor RPM) x lift speed.

b. P.2.2.3.1 - levelling speed is set at 0.05 m/s

c. P.2.2.3.2 - full speed, set at 0.5 m/s (if the lift speed is below 0.5 m/s set to contract

speed).

d. P2.2.3.3 - intermediate speed, set at 0.5 m/s (if the lift speed is below 0.5 m/s set to

contract speed).

e. P2.2.3.4 - inspection speed, set to the desired speed but no greater than 0.25 m/s.

! Tech Tip: for a 4 pole motor the synchronous speed is 1500

rpm, for a 6 pole motor the synchronous speed is 1000 rpm

and for an 8 pole motor the synchronous speed is 750 rpm.



22

Open Loop parameters (f - g inclusive)

f. P2.3.1.1 - current limit, in the brake control group. Set this parameter to 0.1 x motor

full load current.

g. P2.3.1.9 - DC brake current, in the brake control group. Set this parameter to 0.9 x

motor full load current.

Closed loop parameters (h only)

h. P2.3.2.1 - current limit, in the brake control group. Set this parameter to 0.1 x motor

full load current.

i. P2.11.1 - magnetising current, in the closed loop parameters. Set this parameter to

0, which will allow the drive to estimate the magnetising current based on the motor

data.

You are now ready to perform the auto tune.

8.2 Auto-tune (motor identification)

The auto tune is done to help the drive determine the motor model there are 2 types of auto tune in

the Vacon drive, one which can be performed with the ropes on the lift(ID no run) and one which

requires the lift to have the ropes removed(ID with run).

8. The standard auto tune normally performed is the static auto tune (ID no run). To perform

this auto tune follow the instructions below:

a. Switch the lift off and isolate the brake by switching of the circuit breaker for the

supply of the brake shown on the drawings, switch the lift on.

b. In the drive set the parameter P2.5.12 – identification, in the motor control group to

ID no run.

c. Once the parameter has been set in, an instruction to run up or down should be

given within 10 seconds. The panel will energise and switch on the contactors. The

motor will energise and “Hum” but not run. If the lift runs, immediately stop the lift

and restart the process.

d. After approximately 20 seconds the drive should switch the identification parameter

back to no action. (The id run has been successful).

e. Check the parameters P2.5. 6 - U/F mid freq, P2.5.7 U/F - mid volt and P2.5.8 - zero

freq volts are not set at 0, if these parameters are set at 0 then the Id run has notbeen successful, and needs to be rerun.

! Tech Tip: To switch the lift to closed loop control go to the motor control

parameters and set the parameter P2.5.1 - control mode to Closed Loop, andensure the parameter P2.8.4.2 - Shaft Speed Fault is set to no action.

! Tech Tip: to switch the lift to open loop control go to the motor control

parameters and set the parameter P2.5.1 - control mode to O/L speed control,

and ensure the parameter P2.8.4.2 - Shaft Speed Fault is set to no action.




2323

f. Switch the lift off and switch on the brake circuit breaker.

8.3 Direction check

9. Check it is okay to run the lift up and then switch the lift on, and run the lift up, the UPR

relay should energise and the lift should run up. If the lift does not run up swap 2 of the

phases on the motor and repeat the test.

10. Run the lift down and the DNR relay should energise and the lift should run down.

You are now ready to run the lift on inspection control.

8.4 Open loop commissioning

These instructions are for commissioning the lift with an open loop drive for lift speeds of 1 m/s and

less. The correct tuning is required to get good motor torque properties at low speeds, which willgive accurate floor levels and a smooth start and stop of the lift. The open loop sensor-less flux

vector Vacon drive utilises sophisticated algorithms in the software to give very good performance

on a low speed lift. Following these procedures will allow the tuning of the algorithms to give you

the optimum performance of the drive.

11. Check the start up procedure in 1 - 7 has been done

12. If the auto tune has not been performed all or you are unsure if the auto tune has been

performed then it is recommended that you follow the instructions in no 8.

13. Check the speed of the lift and ensure the slowing limits have been set to the correct

distances shown on the drawings. If using a tape head ensure the floor levels and slowingdistances have been as accurately as practically possible to their operational distances.

14. Ensure the lift can run safely and trouble-free in the shaft i.e. not tipping locks, etc.

8.5 Setup High Speed

15. Place a lift on normal, and slowly increase the speed of the lift until high-speed is obtained. If

the lift begins to overshoot the floor level and then the deceleration 1 parameter should be

increased to prevent this. Also monitor the output frequency and ensure when running up

no-load the output frequency is not 50 Hz or above, the output frequency should be

normally approximately 45 to 48 Hz.

8.6 Setup Levelling Speed

16. Check the parameter P2.2.3.1 levelling speed is set at 0.05 m/s (10 ft/m). Increase the

deceleration rate so that the lift runs for approximately 10 to 15 seconds on levelling speed,

now monitor the levelling speeds both in the up and down direction and ensure they are

within 5% of each other. . If the lift runs faster in the up and then to equalise speeds reduce

the parameter P2.1.3 motor nominal speed (200 RPM Max) in the motor parameters. If the

lift runs faster in the down then to equalise the speeds increase the parameter P2.1.3 motor

nominal speed (200 RPM Max).

17. Check the parameter P2.4.3 frequency limit in the drive control group is approximately 1Hz

above the levelling speed.

18. Monitor the speed in the up and down direction. The speed of the lift should be within 5% in

the up and down direction.

19. Now reduce the deceleration rate of the lift to ensure you maintain levelling speed for

approximately 1.5 seconds.




2525

8.7 Setup Lift Stopping

20. Adjust the parameter P2.3.1.12 DC braking frequency, in the mechanical brake control

parameters to ensure the lift stops accurately, reduce the frequency to obtain a more

accurate stop. Adjust the parameter P2.3.1.6 mechanical brake close delay so that the brake

energises approximately 0.25s after the lift has stopped. This will help obtain accurate floor

levelling.



26

21.

Now ensure the lift stops smoothly and the brake is adjusted such that it performs it

required function, but the lift of the brake is reduced to minimise the noise on stopping.

8.8 Setup Lift Starting

22. Check now the start of the lift and it should be smooth and accelerate comfortably away

from the floor level. If the start of the lift drives against the brake the brake release time can

be reduced by adjusting the parameter P2.3.1.4 brake open delay in the brake control group,

so that the lift starts smoothly. If the lift rolls back then again this time can be increased.

23. Now adjust the acceleration rate if required by adjusting parameter P2.2.5.1 Acceleration 1,

in the speed curve 1 group. To increase the time to high speed, reduce this value. To

decrease the time taken to high speed, increase this value.

8.9 Brake Stall Check

24. An important function of the drive safety is to ensure that it is not possible to drive through

the brake, with the lift switched off isolate the supply via the circuit breaker for the brake

shown on the drawings. Switch the lift on and the lift should try to run, after approximately

2 seconds the drive should trip on F57 Torque supervision. The lift motor should not drive

through the brake. Reconnect the brake.

8.10 Final Checks

25. Now setup the floor levels on the lift and adjust to suit, and perform all the necessary safety

checks before the lift is placed into service.




2727

8.11 Closed loop commissioning

The following instructions are for commissioning the Vacon drive in closed loop with encoder

feedback. With the encoder feedback the Vacon drive is a flux vector drive with very fast and

accurate speed dynamic speed response which will give you an accuracy of 0.01%. When in closed

loop mode there are different parameter adjustments than when in open loop mode. Following

these procedures should give the optimum results on closed loop operation.

11. Check the start up procedure in 1 - 7 has been done.

12. If the auto tune has not been performed at all or you are unsure if the auto tune has been

performed then it is recommended that you follow the instructions in no 8.

13. Check the speed of the lift and ensure the slowing limits have been set to the correct

distances shown on the drawings. If using a tape head ensure the floor levels and slowing

distances have been as accurately as practically possible to their operational distances.14. Ensure the lift can run safely and trouble-free in the shaft i.e. not tipping locks, etc.

8.12 Closed Loop Encoder Operation

15. Set the drive in closed loop mode by setting parameter P2.5.1 2-motor control to closed

loop. Check the parameter P7.3.1.1 - Encoder PPR, in the Expander Board Menu is set

correctly. Run the lift and if the drive trips check if the sub code of the fault is 4, if it is 4 the

encoder direction is wrong and can be changed by adjusting P7.3.1.1 encoder direction.

16. Place the lift at the lowest level and set the drive to monitor the motor current, run the lift

in the up direction and the current should be between 30 to 45% of the motor nominal

current. If this is not the case then the magnetising current may be set wrong and will need

to be calculated using the following formula and set into the parameter P2.11.1-magnetising

current, in the closed loop group:

Im = In x (((5 x √ (1-cosⱷ2))-1)/ (5 - √ (1-cosⱷ

2)))

Where: Im is the magnetising current

In is the nominal motor current

Cosⱷ is the power factor of the motor

17. ensure the following parameters in the closed loop menu are set to the following values:

P2.11.2 speed control limit 1 - 5.00Hz

P2.11.3 speed control limit 2 - 5.00HzP2.11.4 speed control KP1 - 30

! Tech Tip: the cos Phi (ⱷ) of the motor should be stamped on the motor data plate. This

is an indication of the efficiency of the motor and the value is normally related to theslip of the motor. If the slip of the motor is relatively low (motor RPM 1430 - 1470) then

the figure for cos Phi is normally between 0.83 - 0.85. If the slip of the motor is

relatively high (motor RPM 1300- 1400) then the cos Phi is normally between 0.7 and

0.75



28

P2.11.5 speed control KP2 - 30

P2.11.6 speed control Ti 1 - 25

P2.11.7 speed control Ti 2 - 25

18. ensure the following parameters in the brake control menu are set to the following values:

P2.3.2.4 Brake Open Delay - 0.05s

P2.3.2.15 Start Mag Time - 0.15s

P2.3.2.16 start Mag current - magnetising current value

8.13 Setup High Speed

19. Place the lift on normal, and slowly increase the speed of the lift until high-speed is

obtained. If the lift begins to overshoot the floor level and then the deceleration 1

parameter should be increased to prevent this. Also monitor the output frequency and

ensure when running up no-load the output frequency is not 50 Hz or above, the output

frequency should be normally approximately 45 to 48 Hz.

8.14 Setup Levelling Speed

20. Check the parameter P2.2.3.1 levelling speed is set at 0.05 m/s (10 ft/m). Increase the

deceleration rate so that the lift runs for approximately 10 to 15 seconds on levelling speed,

now monitor the levelling speeds both in the up and down direction and ensure they are

within 1-2% of each other

21. Check the parameter P2.4.3 frequency limit in the drive control group is approximately 1Hzabove the levelling speed.

22. Monitor the speed in the up and down direction. The speed of the lift should be within 1-2%

in the up and down direction.

23. Now reduce the deceleration rate of the lift to ensure you maintain levelling speed for

approximately 1.5 seconds.




2929

8.15 Setup Lift Stopping

24. Adjust the parameter P2.3.2.6 mechanical brake close delay so that the brake releases

approximately 0.25s after the lift has stopped. This will help obtain accurate floor levelling.

The lift should stay at 0 speed after the mechanical brake has released, if this is not the case

then increase parameter P2.3.2.10 - 0Hz time stop to stay energised 0.25s after the brake is

released (up to max 1.5s).

25. Now ensure the lift stops smoothly and the brake is adjusted such that it performs it

required function, but the lift of the brake is reduced to minimise the noise on stopping.



30

8.16 Setup Lift Starting

26. Check now the start of the lift and it should be smooth and accelerate comfortably away

from the floor level. If the start of the lift drives against the brake the brake release time can

be reduced by adjusting the parameter P2.3.1.4 brake open delay in the brake control group,

so that the lift starts smoothly. If the lift can't get satisfactory starting operation by adjusting

the brake opening delay then you may increase the parameter P2.3.2.11 smooth start time

with the parameter P2.3.2.12 Smooth St Freq set at 0 or very low.

! Tech Tip: the Vacon drive contains a sophisticated rollback controller which detects the

number of pulses typically 1 (set in P2 .5.18.12) moved once the brake has energised, and holds

the lift at 0 speed until the 0 Hz time at start has finished (P 2.3.2.9), the level of the hold value

is set in the roll back controller gain (P 2.5.18.11) and is typically set at 2500.




3131

27.

Now adjust the acceleration rate if required by adjusting parameter P2.2.5.1 Acceleration 1,

in the speed curve 1 group. To increase the time to high speed, reduce this value. To

decrease the time taken to high speed, increase this value.

8.17 Brake Stall Check

28. An important function of the drive safety is to ensure that it is not possible to drive through

the brake, with the lift switched off isolate the supply via the circuit breaker for the brake

shown on the drawings. Switch the lift on and the lift should try to run, after approximately

2 seconds the drive should trip on F57 Torque supervision or F43 encoder fault. The lift

motor should not drive through the brake. Reconnect the brake.

8.19 Final Checks

29. Now setup the floor levels on the lift and adjust to suit, and perform all the necessary safety

checks before the lift is placed into service.

! Tech Tip: if there is vibration in the journey or the lift seems sluggish to respond then the

parameters to adjust are located in the closed loop parameter group:



P2.11.6 speed control Ti 1 - 25P2.11.7 speed control Ti 2 - 25

These parameters should be adjusted together and to the same values i.e. KP 1 and KP 2 should

always be the same value, and Ti 1 and Ti 2 should always be the same value.

Adjusting the KP values will cause vibration if they are too high and make the lift sluggish if they are

too low. The Ti values have the opposite effect if they are too high they make the lift sluggish and if

they are too low they can cause vibration.

The value selected have been optimised to a standard lift, generally adjust the gain first until you getvibration, then adjust it back until the vibration has disappeared. If this is not possible or does not

produce the desired results then reduce the Ti values until you get vibration and then increase a little

until the vibration has disappeared.



32

9.0 Copying parameters

The parameters can be easily copied from one drive to another to allow ease of setting up or in a

rare case of a drive having to be changed allows the parameters that were stored in the existing

drive to be downloaded to the new drive.

Before any parameters can be successfully copied from one drive to another drive the drive has to

be stopped when the parameters are downloaded to it.

To upload the parameters place the lift on inspection and follow the instructions below:

To download the parameters is similar to uploading to keypad, instead of up to keypad, select down

from keypad with a lift on inspection control.

P2.11.2 Speed ctrl limit 1 5 Hz Not used

P2.11.3 Speed ctrl limit 2 5 Hz Not use

P2.11.4 Speed control KP 1 30 Adjusts the speed control gain below 5 Hz (should

be set at the same value as KP2)

P2.11.5 Speed control KP2 30 Adjust the speed control gain above 5 Hz this

adjusts the reaction of the motor to changes in

load. See the main parameter descriptions for

operation

(should be set at the same value as KP2)

P2.11.7 Speed control TI 2 25 Adjusts the integral time of the speed control

gain loop. This adjusts the reaction of the motor

to changes in load. See the main parameter

descriptions for operation.

P2.11.8 Current control KP 40 Adjust the inner current loop of the drive(not

normally required seek advice from the factory)P2.11.9 Current control TI 1.5 Time constant of the inner current loop



P2.11.10 Encoder filter time 3 ms Adjusts the filter time of the encoder feedback

(normally set at 3 ms)

P2.11.11 Slip adjust 100% This parameter is used to adjust the motor

voltage when loaded. Reducing the slip adjust

value increases the motor voltage when loaded.
