5.7.2 Commutation
offset
adjustment
To adjust the offset between the commutation feedback and the phase currents the parameter
commutation_offset_adjustment
can be used. The following steps have to be followed:
1. Make sure the rotor can turn freely.
2. Initialize correct motor parameters.
3. Set
commutation_feedback
(resolver or encoder).
4. Set the drive to torque mode. (set parameter
control_loop_mode_requested
(Field Number 1330) to
1301)
5. Set
commutation_offset_adjustment
to 1 to start the adjustment procedure.
6. Enable the drive. The communication adjustment starts.
7. Wait
until
commutation_offset_adjustment
reads 0 (after about 2 seconds).
The parameter
commutation_offset
now contains the right value to allow commutation with the feedback device
selected. Make sure to save the value to EEPROM.
