options. In winder applications, the feed-forward
factor is typically the line speed of the system.
7-52 Process PID Feed Fwd Ramp up
Range:
Function:
0.01 s
*
[0.01 - 10 s] Controls the dynamics of the feed-forward
signal when ramping up.
7-53 Process PID Feed Fwd Ramp down
Range:
Function:
0.01 s
*
[0.01 - 10 s] Controls the dynamics of the feed-forward
signal when ramping down.
7-56 Process PID Ref. Filter Time
Range:
Function:
0.001 s
*
[0.001 - 1
s]
Set a time constant for the reference 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.
7-57 Process PID Fb. Filter Time
Range:
Function:
0.001 s
*
[0.001 - 1
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.
