Preconditions for the execution
• The motor is operated in speed open-loop control and servo control.
• During the resolver error identification, the speed should be constant, if possible, and greater
than 500 rpm.
Response of the motor during the execution
• The response of the motor corresponds to the speed setpoint.
• The motor may be running rough during identification. This is due to the identification method.
How to identify the resolver error characteristic:
1. Set object
(or
• The progress of the procedure is shown in object
for axis B).
• After successful completion of the resolver error identification, the following
parameters of the resolver error compensation are automatically written. The resolver
now operates with these settings.
2. For permanent storage: After the procedure has been completed, upload the changed
parameters (
or
for axis B) from the i700 servo inverter into the Controller.
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.

0x2C44 | 0x3444 - Resolver error compensation: Parameter
Note!
The detected gain can take values between 0 ...100 %.
• With a setting of 0 %, the gain of the corresponding resolver track is only 95 % of the
Lenze setting.
• With a sensible resolver error compensation only one of the two gains is adapted. The
other remains at 100 %.
