	(G166)				Type: O2	Offline
		0	No field is used (e.g. in the case of permanent-field motors). The
			field gating pulses are disabled. Unlike all other cases, the motor
			flux (K0290) is not calculated according to the field characteristic
			(P120 to P139) as a function of the actual field current (K0265),
			but set to the value for 100% rated flux.
			Internal field power module
		1	The field is switched with the line contactor - this setting must be
			selected if the mains supplies for the field and armature power
			sections are connected or disconnected simultaneously (field
			gating pulses are enabled/disabled at the same time as the line
			contactor is closed/opened, the field current decays with the
			field time constant).
		2	Automatic injection of standstill field set in P257 after expiry of a
			time period set in P258, after converter has reached operating
			state o7 or higher.
		3	Field ACTIVE continuously.
		4	The field is switched with the "Auxiliaries ON“ (B0251) signal

External field power module (40.00A field)

11Board C98043-A7044 (40A field power module) is inserted at connector X102 on board C98043-A7002 or C98043-A7003. The field is controlled as described in para. 1.

12As described in para. 11, but

the field is controlled as described in para. 2.

13As described in para. 11, but

the field is controlled as described in para. 3.

14As described in para. 11, but

the field is controlled as described in para. 4.

External field device

21An external field device is used. The setpoint for the external field device is supplied via connector K0268 (e.g. via an analog output or the peer-to-peer interface).

The rated DC current of the external field device is set in parameter U838. This value is also displayed in parameter r073.001. P076.002 is inoperative.

If the external field device supplies an actual field current signal, then this can be fed in at P612. If not, then P263 should be set to 1 or 2.

If the external field device supplies an "I field < I field min“ signal, then this can be fed in at P265.

The field is controlled as described in para. 1.

22As described in para. 21, but

the field is controlled as described in para. 2.

23As described in para. 21, but

the field is controlled as described in para. 3.

24As described in para. 21, but

the field is controlled as described in para. 4.

NOTICE

Even though changes to the parameter value from > 0 to = 0 are accepted in operating states of ≥ o1.0, they do not take effect until the converter reaches an operating state of ≥ o7.0.

[Values 11 to 24 can be set only in SW 1.9 and later]
