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)
P2236[0...2] BI: Enable PID-MOP (DOWN-cmd)
This parameter defines source of DOWN command.
Possible sources: 19.14 (BOP), 722.x (Digital Input), 2036.14 (USS
on RS485)
Additional commissioning parameters
P2251
PID mode
= 0: PID as setpoint (factory default)
= 1: PID as trim source
P2253[0...2] CI: PID setpoint
This parameter defines setpoint source for PID setpoint input.
Possible sources: 755[0] (Analog input 1), 2018.1 (USS PZD 2),
2224 (Actual fixed PID setpoint), 2250 (Output setpoint of PID-MOP)
P2254[0...2] CI: PID trim source
This parameter selects trim source for PID setpoint.
Possible sources: 755[0] (Analog input 1), 2018.1 (USS PZD 2),
2224 (Actual fixed PID setpoint), 2250 (Output setpoint of PID-MOP)
P2255
PID setpoint gain factor
Range: 0.00 to 100.00 (factory default: 100.00)
P2256
PID trim gain factor
Range: 0.00 to 100.00 (factory default: 100.00)
P2257
Ramp-up time for PID setpoint [s]
Range: 0.00 to 650.00 (factory default: 1.00)
