0 0 Closed-loop current control and current limitation
0 1 Closed-loop torque control with torque limitation (the
torque setpoint is converted to a current setpoint: Current
setpoint = torque setpoint / motor flux)
Current limitation is active additionally
1 0 Closed-loop current control with torque limitation (the
specified torque limit is converted to a current limit:
Current limit = torque limit / motor flux)
Current limitation is active additionally
1 1 Do not set!
Note:
A valid field characteristic (P117=1) must be available when P169 or
P170=1. If one is not, the optimization run for field weakening (P051=27)
must be executed.
P263 determines the input quantity for the motor flux calculation.
