7-51 Process PID Feed Fwd Gain
Range:
Function:
the reference whereas
has more choices. In winder
applications, the feed fwd factor will
typically be the line speed of the system.
7-52 Process PID Feed Fwd Ramp up
Range:
Function:
0.01 s
*
[0.01 - 10.00 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 - 10.00 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 -
1.000 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 -
1.000 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.
