Fault
113
Detects a broken or unplugged fiber (F or F1) between the signal interface board
and the master gate drive board for the U-Phase. If the signal is off for more
than 5 mS, the fault will occur.
Unknown
Fault
1
This fault should not occur. Contact Baldor for service.
Upper U Gate
Fault
39
Transistor #1 failed to fire or misfired. Verify IGBT is not shorted. Verify no
debris has fallen into drive. Check wiring between drive and motor. Verify motor
windings are not shorted.
Upper V Gate
Fault
41
Transistor #2 failed to fire or misfired. Verify IGBT is not shorted. Verify no
debris has fallen into drive. Check wiring between drive and motor. Verify motor
windings are not shorted.
Upper W Gate
Fault
43
Transistor #3 failed to fire or misfired. Verify IGBT is not shorted. Verify no
debris has fallen into drive. Check wiring between drive and motor. Verify motor
windings are not shorted.
User 24V
Fault
14
User 24V supply out of tolerance. Measure 24V supply using a digital multi-
meter at terminals J1-23 and J1-24. If voltage is not correct, remove all external
control connections and repeat measurement to determine if problem is with
external connections or with the power supply.
User Ref
Fault
13
User analog input reference out of tolerance. Check connections for proper
shielding and grounding; check for excessive noise on analog signals. If
problem persists, contact Baldor for service.
V Fiber COM
Fault
115
Detects a broken or uplugged fiber (F or F1) between the signal interface board
and the master gate drive board for the V-Phase. If the signal is off for more
than 5 mS, the fault will occur.
W Fiber COM
Fault
117
Detects a broken or uplugged fiber (F or F1) between the signal interface board
and the master gate drive board for the W-Phase. If the signal is off for more
than 5 mS, the fault will occur.
