			and save the setting.
	20 = Set voltage vector.		When P1910=1, Alarm A0541
			(motor data identification active)
			is output and internally P0340 is
			set to 3.
			Initiate the measuring operation
			with a continuous (steady-state)
			ON command.
			The motor aligns itself and
			current flows through it.
			Diagnostics are possible using
			r0069 (CO: phase current).
			On completion of the motor
			data identification routine,
			P1910 resets (P1910=0, motor
			data identification routine
			inhibited) and Alarm A0541 is
			cleared (deleted).
		5. To set the SED2 into a defined
			state, issue an OFF1 command.
