Analog PID Reference Signals
Parameters A110 [Anlg In 0-10V Lo] and A111 [Anlg In 0-10V Hi] are
used to scale or invert an analog PID Reference.
Important: Firmware version FRN 2.xx also allows PID Feedback
scaling from an analog input.
Examples
Scale Function
For a 0-5 volt signal, the following parameter settings are used so that a 0
volt signal = 0% PID Reference and a 5 volt signal = 100% PID
Reference.
•
A110 [Anlg In 0-10V Lo] = 0.0%
•
A111 [Anlg In 0-10V Hi] = 50.0%
•
A132 [PID Ref Sel] = 0 “0-10V Input”
