FDS						Type: O2	Offline
	0	0	Closed-loop current control and current limitation
(G160)	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.
