PID controller

P2200 =... BI: Enable PID controller
PID mode Allows user to enable/disable the PID controller. Setting to 1 enables the PID
controller. Setting 1 automatically disables normal ramp times set in P1120 and P1121 and
the normal frequency setpoints.
PID mode
r2251 =...
Configuration of PID controller.
0 PID as setpoint
1 PID as trim
P2253 =... CI: PID setpoint
Defines setpoint source for PID setpoint input.
CI: PID trim source
P2254 =...
Selects trim source for PID setpoint. This signal is multiplied by the trim gain and added to
the PID setpoint.
Ramp-up time for PID setpoint
P2257 =...
Sets the ramp-up time for the PID setpoint.
Ramp-down time for PID setpoint
P2258 =...
Sets ramp-down time for PID setpoint.
CI: PID feedback
P2264 =...
Selects the source of the PID feedback signal.
Max. value for PID feedback
P2267 =...
Sets the upper limit for the value of the feedback signal in [%]..
Min. value for PID feedback
P2268 =...
Sets lower limit for value of feedback signal in [%]..
CO: PID error
r2273 =...
Displays PID error (difference) signal between setpoint and feedback signals in [%].
PID derivative time
P2274 =...
Sets PID derivative time.
P2274 = 0:
The derivative term does not have any effect (it applies a gain of 1).
PID proportional gain
P2280 =...
Allows user to set proportional gain for PID controller.
PID integral time
P2285 =...
Sets integral time constant for PID controller.
PID output upper limit
P2291 =...
Sets upper limit for PID controller output in [%].
PID output lower limit
P2292 =...
Sets lower limit for the PID controller output in [%].
