5.6.2.4 Setting the PID controller
Functionality
The integrated PID controller (technology controller) supports all kinds of simple process
control tasks, e.g. controlling pressures, levels, or flowrates. The PID controller specifies the
speed setpoint of the motor in such a way that the process variable to be controlled
corresponds to its setpoint.

Setting parameters
Parameter Function Setting
Main function parameters
P2200[0...2] BI: Enable PID controller This parameter allows user to enable / disable the PID
controller. Setting to 1 enables the PID closed-loop controller.
Setting 1 automatically disables normal ramp times set in
P1120 and P1121 and the normal frequency setpoints.
Factory default: 0
P2235[0...2] BI: Enable PID-MOP (UP-cmd) This parameter defines source of UP command.
Possible sources: 19.13 (BOP), 722.x (Digital Input), 2036.13
(USS on RS485)
