PID Feedback Display Scaling
The PID feedback signal can be scaled to represent actual engineering units. Use parameter 10-33 to set the
feedback signal maximum scaling.
Example:
Feedback signal is a pressure transducer (0-10V/0-20mA) with a range of 0
– 200 PSI
0V/0mA = 0 PSI, 10V/20mA = 200 PSI.
Set parameter 10-33 to 200 maximum of transducer range (100%).
