Siemens 6RA70 specifications F006 Undervoltage, F007 Overvoltage

Fault			Description
No.		Cause as a function of fault value			Further information (r047.002 to r047.016)
		(r047.001, r949.001 or r949.009 with acknowledged error)
	Fault value:
	1	Voltage failure occurred in the field supply (terminals 3U1 and 3W1) (if P086 = 0)
	2	Delay time according to P089 elapsed in state o5.1 (waiting for voltage at the field power section)
	3	Delay time according to P089 elapsed in state o5.0
		(waiting until Ifield act (K0265) is > 50% of the instantaneous field current setpoint K0268)
		[threshold settable in P396 as of SW 1.9]
	4	After P086 > 0 has elapsed (time for automatic restart) in operating state ≤ o4:
		Voltage failure in the field supply or Ifield act (K0265) < 50% Ifield set (K0268) for longer than 500 ms
		[settable via P396 and P397 as of SW 1.9]
	5	When P086 = 0 (no automatic restart) in operating state ≤ o4:
		Ifield act (K0265) < 50% Ifield set (K0268) for longer than 500 ms
		[settable via P396 and P397 as of SW 1.9]
	6	If field reduction before field reversal, I_field ≤ I_field_min (P394) is not reached within 30 s
	7	If field build-up after field reversal, I_field > I_field_x (P398) is not reached within 30 s
F006	Undervoltage
	(active in operating states of ≤ o4)
	The voltage at terminals 1U1, 1V1 or 1W1 and 3U1, 3W1 is lower than the response threshold for longer than the “restart time”
	set in P086.
	Response threshold for armature supply voltage:
		P078.001∗ (1+ P351 )
		100%
	Response threshold for field supply voltage:
		P078.002 ∗ (1+ P351 )
		100%
	Possible fault causes
	♦	Line undervoltage
	♦ Monitoring values set too sensitively or incorrectly (P351, P078)
	Fault value:			r047 Index 002 to 016:
	1	Undervoltage has occurred			i002 Number of phase that has activated fault message
					0 ... Phase UV
					1 ... Phase VW
					2 ... Phase WU
					3 ... Phase field
					i003 Incorrect voltage value (normalized to 16384)
	4	Undervoltage persists for longer than time set in		-
		parameter P086 (if this is set to >0)
F007	Overvoltage
	(active in operating states of ≤ o4)
	The voltage at terminals 1U1, 1V1 or 1W1 and 3U1, 3W1 is higher than the response threshold (for longer than the “restart time”
	set in P086).
	Response threshold for armature supply voltage:
		P078.001∗ (1+ P352 )
		100%
	Response threshold for field supply voltage:
		P078.002 ∗ (1+ P352 )
		100%
	Possible fault causes
	♦	Line overvoltage
	♦ Monitoring values set too sensitively or incorrectly (P352, P078)
