Enabling Process PID Control (F359)
To operate the Q9 in Process PID mode, Parameter F359 (PID Control Switching) must be set to “1:
Process PID”.
PID Feedback Signal Selection (F360)
A feedback signal from a transducer needs to be sent to the drive in order for PID control to function
properly. The type of signal being used to measure the system variable determines what the value of
Parameter F360 should be set to. In most cases, the feedback signal from the transducer is a 4-20
mA signal and F360 should be set to “1: V/I”.
