Note:
•
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
) have been set
•
The speed feedback has been monitored for noise, vibrations and other
disturbances caused by the mechanics of the system, and
•
speed feedback filtering (parameter group
)
•
speed error filtering (parameter group
24 Speed reference conditioning
and
•
zero speed (parameters
and
) have been set to eliminate these
disturbances.
•
The drive has been started and is running in speed control mode.
