7-57 Process PID Fb. Filter Time
Default value: 0.001 s

Set a time constant for the feedback first-order low-pass filter. The low-pass filter improves steady-state performance and dampens
oscillations on the reference/ feedback signals. However, severe filtering can be detrimental to dynamic performance.

Default value: Size related
Conversion index: –
This parameter cannot be adjusted while the motor is running.
Select the source of the control word: 1 of 2 serial interfaces or 4 installed options. During initial power-up, the drive automatically
sets this parameter to [3] Option A if it detects a valid fieldbus option installed in slot A. When the option is removed, the drive
detects a configuration change, sets parameter 8-02 Control Word Source to default setting [1] FC RS485, and trips. If an option is
installed after initial power-up, the setting of parameter 8-02 Control Word Source does not change, but the drive trips and shows:
Alarm 67, Option Changed. When retrofitting a bus option into a drive that did not have a bus option installed earlier, change the
control to bus-based. This change is required for safety reasons to avoid an unintended change.
