ms*
[5 -
1000 ms]
NOTICE
This parameter cannot be adjusted
while the motor is running.
Enter the pulse lter time constant. The
pulse
lter 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 lter.
5-55 Term. 33 Low Frequency
Range: Function:
100 Hz* [0 - 110000
Hz]
Enter the low frequency corresponding
to the low motor shaft speed (that is
low reference value) in
parameter 5-57 Term. 33 Low Ref./Feedb.
Value.
5-56 Term. 33 High Frequency
Range: Function:
100 Hz* [0 - 110000
Hz]
Enter the high frequency corresponding
to the high motor shaft speed (that is
high reference value) in
parameter 5-58 Term. 33 High Ref./Feedb.
Value.

5-59 Pulse Filter Time Constant #33
Range: Function:
100
ms*
[5 - 1000
ms]
NOTICE
This parameter cannot be adjusted
while the motor is running.
5-59 Pulse Filter Time Constant #33
Range: Function:
Enter the pulse lter time constant. The
low-pass lter reduces the inuence and
dampens oscillations on the feedback
signal from the control.
This is an advantage if there is a lot of
noise in the system.
3.7.6 5-6* Pulse Outputs
Parameters for conguring 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.
