Code Description
4009 100% VALUE
Defines (together with the previous parameter) the scaling applied to
the actual values of the PID controller.
• Units and scale are defined by parameters 4006 and 4007.
4010 SET POINT SEL
Defines the reference signal source for the PID controller.
• Parameter has no significance when the PID regulator is by-passed
