	134Hex	Basic sampling time T0.			[ms]	1.5	3 /	A
		Setting instructions:
		• When the sampling time is reduced, the available
		computing time should be checked via parameter r725 in
		the "Run" state. At least 5 % of the available computing
		time should always be left in reserve to avoid any delayed
		(slow) execution of operator inputs.
		• If fault F042 "Computing time" occurs, the sampling time
		setting must be increased again.

P325		MC switch-on del			0.0 to 30.0	−	3 /	BR
145Hex		Delay time for closing (energizing) the main contactor.			[s]	0.0	3 /	B
		By delaying energization of the main contactor, it is possible to
		charge the DC link up to the line voltage peak value via the
		precharging resistors. This measure will be necessary if the
		external DC-link capacitance connected to the AFE is
		significantly higher than that of the AFE.
		Type=O2;	PKW: 1HEX=0.1 s	PZD Gr.: −
	P326	Max.pre-chrg. t.			0.1 to 30.0	2	3 /	BR
	146Hex	Maximum precharging time			[s]	i001=3.0	3 /	B
		If the DC link is not successfully precharged within this period,				i002=3.0
		fault message Precharging (F002) or, if the line voltage is too
		low, fault message Line Voltage (F004) is activated.
		RDS(2) parameter
		Type=O2;	PKW: 1HEX=0.1 s	PZD Gr.: 0
	P329	MCInvEnableDel			0.08 to 5.00	−	4 /	BR
	149Hex	Delay between activation of the main contactor and enabling			[s]	0.40	4 /	BR
		of the inverter.
		By increasing this time, it is possible to ensure that the DC link
		is charged up completely to the peak value of the mains
		voltage. This is necessary if the external DC link capacity
		connected to the AFE is considerably greater than that of the
		AFE. The set time should always be at least 100 ms greater
		than the time that the main contactor needs to close the
		contacts.
