P088		Brake closing time		0.00 to 10.00		Ind: None		P052 = 3

		when the "Switch-on" command is not applied, or when the "Fast stop"
(G187)
		command is input, the internal controller disabling signal, and thus the
		thyristor gating pulse disabling signal, is not actually activated after n<nmin
	has been reached until the time delay set in this parameter has elapsed.
	During this period, the drive continues to produce a torque (operating state
	I, II or – –), so as to give the holding brake enough time to close.
P089	Maximum wait time for voltage to appear at power section				0.0 to 60.0	Ind: None		P052 = 3
		When the line contactor has dropped out and the "Switch-on" or "Inching" or			[s]	FS=2.0		P051 = 40
					0.1s	Type: O2		Online
		"Crawling" command is applied, the converter waits in operating states o4
		and o5 for voltage to appear at the power section, for the actual field current
		value (K0265) to reach > 50% of the field current setpoint (K0268). The
		corresponding fault message is activated if no power section voltage and no
		field current is detected. This parameter specifies the maximum total delay
		period in which the drive may dwell in operating states o4 and o5 (response
		threshold for function which checks for voltage at power section, see
		parameter P353).
P090		Stabilization time for line voltage			0.01 to 1.00	Ind: None		P052 = 3
		When the line contactor has dropped out and the "Switch-on" or "Inching" or			[s]	FS=0.02		P051 = 40
					0.01s	Type: O2		Online
		"Crawling" command is applied, or after a phase failure has been detected
		in the armature or field mains supply with active "Automatic restart" function
		(P086>0), the converter dwells in operating state o4 and o5 until voltage
		appears at the power section. Line voltage is not assumed to be applied to
		the power terminals until the amplitude, frequency and phase symmetry
		have remained within the permissible tolerance for a period exceeding the
		setting in this parameter. The parameter applies to both the armature and
		field power connections.
		Caution:
		The setting in P090 must be lower than the settings in P086 (except when
		P086=0.0) and P089!
P091	Setpoint threshold				0.00 to 199.99		Ind: 2		P052 = 3
		i001:	Threshold for function "Switch on only if setpoint is low“	[%]			FS=		P051 = 40
				0.01%			i001: 199.99		Online
			The converter can be switched on only if a setpoint
							i002: 0.00
			K0193 ≤ P091.001 is applied to the ramp-function generator
							Type: O2
			input. If the applied setpoint is higher, the converter dwells in
			state o6 after "switch-on" until the absolute setpoint value is
			≤ P091.001.
		i002:	Threshold for function
			"Automatic pulse disable if setpoint is low“ [SW 2.0 and later]
			If n-set (K0193) and n-act (K0166) are less than P091.002,
			the firing pulses are disabled and the drive goes into state o2.0.
