SETPOINT CHANGES
PFAC_SP specifies the effective P
action when there is a setpoint
change. This is set between 0 and
1.
•
1: P action has full effect if the
setpoint changes.
•
0: P action has no effect if the
setpoint changes.
PROPORTIONAL GAIN
The "proportional gain" input
specifies the controller gain. The
direction of control can be reversed
by giving GAIN a negative sign.
