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
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 %]
