Faults, Warnings and Alarms
DANGER:
A stopped motor may start unexpectedly
if faults occur in electronics of drive, or if
an active fault clears, such as a fault in supply AC
line, or fault in motor connection, or overload.
The VLT 6000 frequency converter outputs faults,
warnings and alarms on the FLN serial bus in a
numerical code. The code numbers are described in
Table 7. The Reset key is used for manually
resetting the drive after an alarm (fault trip). In this
case, the top line of the display will show TRIP
(RESET). If the top line of the display shows TRIP
(AUTO START), the drive will automatically restart. If
the top line of the display shows TRIPLOCK (DISC.
MAINS), input power to the drive must be cycled off
and on again before the trip can be reset.
Refer to the VLT 6000 Operating Instructions for
detailed descriptions.
