28.16 PI TUNE MODE
Activates the speed controller autotune function.
The autotune will automatically set parameters
TIME, as well as
ERR FTIME
The status of the autotune routine is shown by parameter
Notes:
• Before using the autotune function, the following parameters should be set:
• All parameters adjusted during the start-up as described in chapter
•
• Speed scaling and reference ramp settings in parameter group
•
• If the User autotune mode is desired:
• The drive must be in local control mode and stopped before an autotune is requested.
• After requesting an autotune with this parameter, start the drive within 20 seconds.
• Wait until the autotune routine is completed (this parameter has reverted to the value
routine can be aborted by stopping the drive.
• Check the values of the parameters set by the autotune function.

28.17 TUNE BANDWIDTH
Speed controller bandwidth for autotune procedure, User mode (see parameter
MODE).
A larger bandwidth results in more restricted speed controller settings.
0.00 ... 2000.00 Hz
28.18 TUNE DAMPING
Speed controller damping for autotune procedure, User mode (see parameter
MODE).
Higher damping results in safer and smoother operation.
