6-26 Terminal 54 Filter Time Constant
Range: Function:
0.001 s
*
[0.001 - 10
s]
NOTICE
This parameter cannot be adjusted
while the motor is running.
Enter the filter time constant. This is a
first-order digital low-pass filter time
constant for suppressing electrical noise in
terminal 54. Increasing the value improves
dampening but also increases the time
delay through the filter.

6-36 Term. X30/11 Filter Time Constant
Range: Function:
0.001 s
*
[0.001 - 10
s]
NOTICE
This parameter cannot be adjusted
while the motor is running.
Enter the filter time constant. This
constant is a first-order digital low-pass
filter time for suppressing electrical noise
in terminal X30/11. A high value improves
dampening but also increases the delay
through the filter.
