This parameter cannot be adjusted
while the motor is running.
Enter the pulse filter time constant. The
low-pass filter reduces the influence and
dampens oscillations on the feedback
signal from the control.
This is an advantage if there is a lot of
noise in the system.
3.6.6 5-6* Pulse Outputs
NOTICE
These parameters cannot be adjusted while the motor is
running.
These parameters configure pulse outputs with their
functions and scaling. Terminals 27 and 29 are allocated to
pulse output via parameter 5-01 Terminal 27 Mode and
parameter 5-02 Terminal 29 Mode, respectively.

Illustration 3.40 Configuration of Pulse Outputs
Parameters for configuring the scaling
and output functions of pulse outputs.
The pulse outputs are designated to
terminals 27 or 29. Select terminal 27
output in parameter 5-01 Terminal 27
