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.
P2253 =... CI: PID setpoint
Defines setpoint source for PID setpoint input.
P2254 =... CI: PID trim source
Selects trim source for PID setpoint. This signal is multiplied by the trim gain and added to
the PID setpoint.
P2257 =... Ramp-up time for PID setpoint
Sets the ramp-up time for the PID setpoint.
P2258 =... Ramp-down time for PID setpoint
Sets ramp-down time for PID setpoint.
P2264 =... CI: PID feedback
Selects the source of the PID feedback signal.
P2267 =... Max. value for PID feedback
Sets the upper limit for the value of the feedback signal in [%]..
P2268 =... Min. value for PID feedback
Sets lower limit for value of feedback signal in [%]..
P2280 =... PID proportional gain
Allows user to set proportional gain for PID controller.
P2285 =... PID integral time
Sets integral time constant for PID controller.
P2291 =... PID output upper limit
Sets upper limit for PID controller output in [%].
