PI-51 Process PID Feed Fwd Gain
Range:
Function:
1
*
[0 -
100]
The feed forward is used to obtain the desired
level, based on a well-known signal available. The
PID controller then only takes care of the smaler
part of the control, necessary because of unknown
characters. The standard feed fwd factor in
PI-38 Process PID Feed Forward Factor is always
related to the reference whereas PI-51 Process PID
Feed Fwd Gain has more choices. In winder
applications, the feed fwd factor will typically be
the line speed of the system.
PI-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.
PI-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.
PI-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.
PI-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.
PI-60 Process PID Error
Range:
Function:
0 %
*
[-200 - 200 %]
PI-61 Process PID Output
Range:
Function:
0 %
*
[-200 - 200 %]
PI-62 Process PID Clamped Output
Range:
Function:
0 %
*
[-200 - 200 %]
PI-63 Process PID Gain Scaled Output
Range:
Function:
0 %
*
[-200 - 200 %]
