GROUP – 6: PID CONTROL SELECTION
C601: PID Control Selection
The AC DRIVE provides one inbuilt PID controller, which can be used to change the AC DRIVE
output frequency or can be utilized as stand alone module. This parameter is used to validate the PID
operation. When PID is used to control the speed of the AC DRIVE, select PID Output as frequency
reference in A106. The PID output can also be selected for the analog output. This will be useful when
using PID control block as stand alone module.
C602: PID Polarity
This parameter can be used to invert the output of PID as per the system requirement.
C603: PID Reference Input
The PID reference input can be selected from any of the 10 options. The various options include FSV
0-10V, FSI 4-20mA, Vin 0-10V, Iin 4-20mA, Local, Serial,
PLC A-O/P 1, PLC A-O/P 2, PLC A-O/P 3
and PLC A-O/P 4. The value of selected PID reference input is displayed in M109 in %.
