• During the resolver error identification, the speed should be constant, if possible, and greater
than 500 rpm.
• During the resolver error identification, approximately 1900 motor revolutions are covered.
Depending on the speed, an identification run thus takes
• 10 minutes at 600 rpm
• 3 minutes at 2000 rpm
• 1.5 minutes at 4000 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 create the adjustment values for resolver error compensation:
1. Set object 0x2822
(or 0x3022 for axis B) to "9".
• The progress of the procedure is shown in object 0x2823
(or 0x3023 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 (0x2C44
or 0x3444 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. Saving changed parameters safe against mains failure

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 %.
