Range: Function:

This parameter cannot be adjusted
while the motor is running.
Enter the pulse filter time constant. The
pulse filter dampens oscillations of the
feedback signal, which is an advantage if
there is a lot of noise in the system. A high
time constant value results in better
dampening, but also increases the time
delay through the filter.

Programming Guide
3.7.6 5-6* Pulse Outputs
Parameters for configuring the scaling and output
functions of pulse outputs. The pulse outputs are
designated to terminal 27 or 29. Select terminal 27 output
in parameter 5-01 Terminal 27 Mode and terminal 29 output
in parameter 5-02 Terminal 29 Mode.
Function:
Enter the low reference
value [RPM] for the motor
shaft speed. This is also
the low feedback value,
see also
parameter 5-52 Term. 29
Low Ref./Feedb. Value.
Function:
Enter the high reference
value [RPM] for the motor
shaft speed. See also
parameter 5-53 Term. 29
High Ref./Feedb. Value.

5-59 Pulse Filter Time Constant #33
Range: Function:
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.
