P360	Response delay for external faults and alarms
(G180)	The fault message or alarm is not activated on the converter until the
	appropriate input or corresponding control word bit (as selected in P675,
(G181)
	P686, P688 or P689) has been in the LOW state for at least the time period
	set in this parameter (see also Section 8, Sheets G180 and G181).
	i001:	Delay for external fault 1
	i002:	Delay for external fault 2
	i003:	Delay for external alarm 1
	i004:	Delay for external alarm 2
P361	Delay time for the undervoltage monitoring		[SW 1.7 and later]
FDS	Activation of the fault message F006 (line undervoltage) is delayed by the
	time that can be set in this parameter. During this delay time firing pulses
	are output!
	Another time which is parameterized for automatic restarting (P086) only
	begins after the time set here has elapsed.
P362	Delay time for the overvoltage monitoring		[SW 1.7 and later]
FDS	Activation of the fault message F007 (line overvoltage) is delayed by the
	time that can be set in this parameter. During this delay time firing pulses
	are output!
	Another time which is parameterized for automatic restarting (P086) only
	begins after the time set here has elapsed.
P363	Threshold for the minimum line frequency		[SW 1.8 and later]
FDS	If the line frequency falls below the value set here and does not rise above it
	again within the "restart" time set in P086, the fault message F008 is
	activated. As long as the line frequency is below the value set here, the
	drive is kept in operating state o4 or o5.
	[values < 45.0 Hz can be set in SW 1.9 and later]

CAUTION

Operation in the extended frequency range between 23 Hz and 110 Hz is available on request.

P364	Threshold for the maximum line frequency	[SW 1.8 and later]
FDS	If the line frequency rises above the value set here and does not fall below it
	again within the "restart" time set in P086, the fault message F009 is
	activated. As long as the line frequency is above the value set here, the
	drive is kept in operating state o4 or o5.

CAUTION

Operation in the extended frequency range between 23 Hz and 110 Hz is available on request.

n < nmin signal

P370	Speed threshold nmin
FDS	Speed threshold for n < nmin limit-value monitor.
(G187)	Note:
	This threshold also affects the sequence of control operations for
	"Shutdown", "Fast stop", cancellation of the "Inching" or "Crawling"
	command, the "Braking with field reversal" function and the brake control
	operation (see Section 9).

P371	Hysteresis for n < nmin signal
FDS	This value is added to the response threshold if n < nmin is active.
