How to perform a resolver error identification run:
1. Select a motor control mode with speed feedback in
• Avoid a speed controller setting that is too tight (motor humming).
• Set the speed ramps as well as the speed setpoint (> 500 rpm).
2. Inhibit the controller, e.g. via the
device command or via a LOW signal at
terminal X5/RFR.
• The controller must be in the "
" status for the resolver error identification
run to be performed.
3. Activate resolver error identification via the
device command = "1: On / start".
4. Enable the controller again.
• The controller changes to the "
" device status.
• The resolver error identification run starts.
• The progress of the identification run can be seen in
• During the resolver error identification run, the direction of rotation of the motor is not
important.
• We recommend to traverse at constant setpoint speed (|nset| > 500 rpm) until resolver
error identification has finished.
• If the application offers only limited space for traversing, reversing is also possible during
active resolver error identification. In this case, ensure that the controller is not inhibited
and that the speed profile is traversed for at least 1 second at constant setpoint speed
(|nset| > 500 rpm).
• The identification is completed if the "0: Off / ready" message is displayed in
5. After the resolver error identification has been completed successfully, the controller can
be inhibited again. (When the controller is inhibited, the "
" device state is quit again.)
6. In order to accept the identified resolver error parameters:
Save parameter set.
Tip!
Resolver error identification can be aborted any time by setting a controller inhibit.
