P092	Delay times for field reversal
(G200)	These times are used to control a reversing contactor for reversing the field
	polarity on a 1-quadrant converter with field reversal.
	i001:	Delay time for the field reduction before opening of the current
		field contactor
		When field polarity reversal is initiated, the delay time set in
		P092.i001 elapsed after reaching Ifield (K0265) < Ifield min
		(P394) before the current field contactor is opened.
	i002:	Delay time before actuation of the new field contactor
		[only SW 1.7 and later]
		After opening the current field contactor the delay time set in
		P092.i002 elapsed before the field contactor for the "new" field
		direction is actuated (drop-out delay time of the contactor use is
		usually longer then the pick-up delay time).
	i003:	Delay time for enabling the field firing pulses
		[only SW 1.7 and later]
		After actuation of the field contactor for the "new" field direction,
		the delay time acc. to P092.i003 elapses before the field firing
		pulses are enabled. This time must be longer than the pick-up
		delay time of the contactor used.
	i004:	Delay time after the field build-up before armature enable
		[only SW 1.7 and later]
		After - directly following the field firing pulse enable - the actual
		field current value Ifield in the "new" field direction has reached
		the value Ifield (K0265) > Ifield set (K0268)*P398/100%, the
		delay time acc. to P092.i004 elapses. Then the internal
		(armature) "Operating enable of field reversal" is issued, i.e. the
		Stopping of the drive in operating state ≥ o1.4 is canceled. This
		delay time permits waiting of the end of overshooting of the
		actual field current value and therefore overshooting of the EMF
		of the DC machine straight after the field current has been built
		up again, before the "armature operating enable" is issued. This
		is intended to prevent armature overcurrents due to excessive
		EMF during overshooting.

P093	Pick-up delay for line contactor
	Pick-up of the line contactor is delayed in relation to "Switch on auxiliaries"
	by the time delay set in this parameter.
P094	Switch-off delay for auxiliaries
	Switch-off of the auxiliaries is delayed in relation to dropout of the line
	contactor by the time delay set in this parameter.
P095	Pick-up time for a contactor in the DC circuit
	If the DC output (terminals 1C1 and 1D1) is switched through to the motor
	via a contactor, and if this contactor is controlled by the "Relay for line
	contactor" (terminals 109 and 110), then the gating pulses may not be
	enabled until the contactor has safely picked up. For this purpose, it may be
	necessary to parameterize an additional delay time for the pick-up
	operation. The timer set in P095 commences during a pick-up operation
	when the converter reaches operating state o5. If the timer has still not run
	down by the time the converter exits state o4, then the converter dwells in
	state o3.2 until the timer has finished.
	During the time period set in P095, the "Main contactor checkback" signal
	must also switch to "1" if this function is activated (see P691). Otherwise the
	converter dwells in state o3.3 until the timer has finished and fault message
	F004 is then output with fault value 6.
P096	After-running time for the device fan	[SW 1.6 and later]

After the drive has been shut down (operating state ≥ 7.0 reached)

the device fan continues to run until the power section has cooled down.

With this parameter you can set the minimum duration for the after-running time.

Note:

If the field current is not switched off after the drive is shut down (see P082), the field current can prevent cooling of the power section. In this case, the equipment blower is never switched off.
