Code Description
4008 0% VALUE
Defines (together with the next parameter) the scaling applied to
the PID controller's actual values (PID1 parameters 0128, 0130
and 0132).
• Units and scale are defined by parameters 4006 and 4007.
4009 100% VALUE
Defines (together with the previous parameter) the scaling applied
to the PID controller's actual values.
• 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 (see 8121
0 = – Control panel provides reference.

11 = 3 ,4 ( ) – Digital inputs, acting as a motor potentiometer control, provide reference.
DI U D RNC
• 3 increases the speed (the U stands for "up")
DI
• 4 decreases the reference (the D stands for "down").
DI
• Parameter 2205
• R = Stop command resets the reference to zero.
• NC = Reference value is not copied.
12 = 3 ,4 ( ) – Same as
DI U D NC
• Stop command does not reset reference to zero. At restart the motor ramps up, at the selected acceleration rate,
to the stored reference.
