Parameter Reference
PID
Setup::Application::PID
Monitor::Application::PID*
This function allows the AC30V to be used in applications requiring a trim to the reference, depending on feedback from an external
measurement device. Typically this will be used for process control, i.e. pressure or flow.
PNO Parameter Descriptions
Setpoint
This is connected to an Analog Input as part of the selected macro.
Feedback
This is connected to an Analog Input as part of the selected macro.
Enable
This is connected to a Digital Input as part of the selected macro. It globally resets the PID output and integral term when FALSE.
Enable must be TRUE for the PID to operate.
Integral Defeat
This may be connected to a Digital Input as part of the selected macro. It resets the p integral term when FALSE.

PID Setpoint Negate
Changes the sign of the Setpoint input
1927
PID Feedback Negate
Changes the sign of the Negate input
1928
PID Proportional Gain
This is the true proportional gain of the PID controller. When set to zero the PID Output is zero.
1929
