99.08 MOTOR NOM

SPEED

This parameter matches the ACS 600 to the nominal speed as

indicated on the motor rating plate.

Note: It is very important to set this parameter exactly to the value

given on the motor rating plate to guarantee proper operation of the

drive. The motor synchronous speed or another approximate value

must not be given instead!

Note: The speed limits in Group 20 Limits are linked to the setting of

99.08 MOTOR NOM SPEED. If value of Parameter 99.08 MOTOR

NOM SPEED is changed, the speed limit settings change automatically

as well.

99.09 MOTOR NOM

POWER

This parameter matches the ACS 600 to the rated power of the motor,

adjustable between 0 kW and 9000 kW.

99.10 MOTOR ID RUN This parameter is used to initiate the Motor Identification Run. During

the run, the ACS 600 will identify the characteristics of the motor for

optimum motor control. The ID Run takes about one minute.

The ID run cannot be performed if the scalar control mode is selected

(Parameter 99.04 MOTOR CTRL MODE is set to SCALAR).

NO

The Motor ID Run is not performed. This can be selected in most

applications. The motor model is calculated at first start by magnetising

the motor for 20 to 60 s at zero speed.

Note: The ID Run (Standard or Reduced) should be selected if:

operation point is near zero speed

operation at torque range above the motor nominal torque within

wide speed range and without any pulse encoder (i.e. without any

measured speed feedback) is required.

STANDARD

Performing the Standard Motor ID Run guarantees that the best

possible control accuracy is achieved. The motor must be de-coupled

from the driven equipment before performing the Standard Motor ID

Run.

REDUCED

The Reduced Motor ID Run should be selected instead of the Standard

ID Run:

if mechanical losses are higher than 20 % (i.e. the motor cannot be

de-coupled from the driven equipment)

if flux reduction is not allowed while the motor is running (i.e. in case

of a braking motor in which the brake switches on if the flux is

reduced below a certain level).

Note: Check the rotation direction of the motor before starting the

Motor ID Run. During the run the motor will rotate in the forward

direction.

WARNING! The motor will run at up to approximately 50 % ... 80 % of

the nominal speed during the Motor ID Run. BE SURE THAT IT IS

SAFE TO RUN THE MOTOR BEFORE PERFORMING THE MOTOR

ID RUN!

ID Run Procedure To perform the Motor ID Run:

Note: If parameter values (Group 10 to 98) are changed before the ID

Run, check that the new settings meet the following conditions:

20.01 MINIMUM SPEED < 0.

20.02 MAXIMUM SPEED > 80 % of motor rated speed.

20.03 MAXIMUM CURRENT > 100*Ihd.

20.04 MAXIMUM TORQUE > 50 %.

1. Ensure that the Panel is in the local control mode (L displayed on

the status row). Press the key to switch modes.

2. Change the selection to STANDARD or REDUCED:

3. Press ENTER to verify selection. The following message will be

displayed:

4. To start the ID Run, press the key. The run enable signal must

be active (see Parameter 16.01 RUN ENABLE).

In general it is recommended not to press any control panel keys

during the ID run. However:

The Motor ID Run can be stopped at any time by pressing the

Control Panel key or removing the Run enable signal.

After the ID Run is started with the key, it is possible to monitor

the actual values by first pressing the ACT key and then the key.
