The diagram below shows the behavior of speed and torque during the autotune
routine. In this example,
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
) 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 (
24 Speed reference conditioning
) and
•
zero speed (parameters
)
have been set to eliminate these disturbances.
• The drive has been started and is running in speed control mode.
After these conditions have been fulfilled, autotuning can be activated by parameter
(or the signal source selected by it).
