Description
Activates/deactivates process PID control.
Note: Process PID control is only available in external
control; see section Local control vs. external control
29).
Process PID control inactive.
Process PID control active.
Process PID control is active when the drive is running.
Selects the primary source of process feedback.
None.

Defines the filter time constant for process feedback.
Feedback filter time.
Defines, together with parameter
scaling, a general scaling factor for the external PID
control chain. The scaling can be utilized when, for
example, the process setpoint is input in Hz, and the
output of the PID controller is used as an rpm value in
speed control. In this case, this parameter might be set to
50, and parameter 40.15
Hz.
In effect, the output of the PID controller [40.15] when
deviation (setpoint - feedback) = [40.14] and [40.32] = 1.
Note: The scaling is based on the ratio between
and 40.15. For example, the values 50 and 1500 would
produce the same scaling as 1 and 3.
Process setpoint base.
See parameter 40.14 Set 1 setpoint scaling
Process PID controller output base.
Selects the primary source of process PID setpoint.
None.
Internal setpoint. See parameter
