5.8.2.1

Enter motor nameplate data

If the equivalent circuit data of the motor required for the motor model are not known, they can

automatically be determined by approximation by the i700 servo inverter by means of the motor

nameplate data before they are set.

How to have the equivalent circuit data determined by the i700 servo inverter:

1. Set the complete motor nameplate data in object

0x2C01

(or

0x3401

for axis).

2. Set the rated motor current in object

0x6075

(or

0x6875

for axis B).

3. Set object

0x2822

(or

0x3022

for axis B) to "3" in order to have the equivalent circuit data

determined by approximation.

• The progress of the procedure is shown in object

0x2823

(or

0x3023

for axis B).

4. For permanent storage: Upload the set equivalent circuit data to the controller from the

i700 servo inverter after the procedure has been completed:

• For asynchronous motor (ASM): Object

0x2C02

(or

0x3402

for axis B).

• For synchronous motor (SM): Object

0x2C03

(or

0x3403

for axis B).

The »EASY Starter« serves to save the parameter settings of the i700 servo inverter as

parameter file (*.gdc). In the »PLC Designer«, this file can then be imported in the

corresponding axis.

Set motor parameters manually

If all required motor data are known (e.g. by means of a data sheet provided by the motor

manufacturer), they can be set manually in the following parameters:
