4.4.5.
S
YNC
L
OSS
This fault indicates that the regen has lost synchronization with the AC line.
This fault will automatically clear if sync is reestablished, and will latch if it
cannot. If this fault recurs regularly or fails to clear, it is likely due to line
noise, a blown phase fuse, or an undersized AC source.
4.4.6.
IGBT D
RIVER
This fault indicates that the regen's internal transistor drive circuitry has
detected an error. This typically indicates an instantaneous overcurrent on
one of the AC legs. This fault will latch until cleared by toggling the Enable
Input. If this fault does not clear, it typically indicates that damage to the
M3645 has occurred.
4.4.7.
P
HASE
1-3 O
VERCURRENT
These faults indicate that the current the M3645 is driving into one leg of the
AC line has exceeded a safe operating level. This is likely due to line noise.
These faults will latch until cleared by toggling the Enable input.
4.4.8.
P
HASE
L
OSS
These faults indicate that the Regen has lost voltage on one or more of the
AC line phases. These faults clear automatically when voltage is
reestablished. If these faults do not clear, it typically indicates that a line fuse
has failed.
4.4.9.
DC U
NDERVOLTAGE
This fault indicates that the DC voltage on the bus is less than 100V. This
fault will clear automatically when the voltage rises to an operable level. If
this fault does not clear, it typically indicates that damage to the M3645 has
occurred.

OMPLETE
These faults indicate that the unit has been powered on in the last ten
seconds. This is normal. This fault will clear automatically. If this fault does
not clear, it typically indicates that damage to the M3645 has occurred.
4.4.11.
F
REQUENCY
D
ETECT
F
AILURE
This fault indicates that the unit failed to properly detect whether the AC
source is 50 or 60 Hz. This fault latches until power-down.
