Fault Description
No.
Cause as a function of fault value
(r047.001, r949.001 or r949.009 with acknowledged error)
Further information (r047.002 to r047.016)
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:

Possible fault causes
• Line undervoltage
• Monitoring values set too sensitively or incorrectly (P351, P078)
Fault value: r047 Index 002 to 016:
1 Undervoltage has occured
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).

Possible fault causes
• Line overvoltage
• Monitoring values set too sensitively or incorrectly (P352, P078)
NOTE
This monitoring function is deactivated in the delivery state. It can be activated via parameter P820.

1 Overvoltage has occurred
002 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)

parameter P086 (if this is >0)
-
F008 Line frequency less than the minimum line frequency acc. to parameter P363
(active in operating states of

o5)
This fault message is activated if the line frequency is less than the minimum line frequency (for longer than the “restart time” set
in parameter P086).
Note: Up to software version 1.7 the threshold for activation of the fault message (minimum line frequency) is 45Hz.
