Notes:
• If the drive cannot produce the requested braking power during the routine,
the results will be based on the acceleration stages only, and not as accurate
as with full braking power.
• The motor will exceed the calculated maximum speed slightly at the end of
each acceleration stage.
Before activating the autotune routine
The prerequisites for performing the autotune routine are:
• The motor identification run (ID run) has been successfully completed
• Speed and torque limits (parameter group
• The drive has been started and is running in speed control mode.
After these conditions have been fulfilled, autotuning can be activated by
