Function:
Select the range of the reference signal and the
feedback signal. Signal values can be positive only,
or positive and negative. The minimum limit may
have a negative value, unless [1] Speed closed loop
control or [3] Process is selected in 1-00 Configu-
ration Mode.
Select the range of the reference signal and the
feedback signal. Signal values can be positive only,
or positive and negative. The minimum limit may
have a negative value, unless [1] Speed closed loop
control or [3] Process is selected in 1-00 Configu-
ration Mode.
For both positive and negative values (both
directions, relative to 4-10 Motor Speed Direction).
Function:
Select the unit to be used in Process PID Control
references and feedbacks. 1-00 Configuration
Mode must be either [3] Process or [8] Extended
PID Control.
