TABLE 7-4. FAULT DESCRIPTIONS
FAULT MESSAGE PROBLEM SOLUTION
BRIDGE (II) T Heatsink overtemperature. a. Undersized motor.
b. Parameter X001: MOTOR IARM
scaled wrong.
c. Parameter X002: MOTOR IFLD scaled
wrong.
d. Check bearings.
e. Check gearbox oil.
f. Replace bridge interface board.
g. Replace micro board.
CNTL POWER Loss of power to the unit. a. If only fault, check plant power.
b. Check other faults.
NOTE: CNTL POWER will appear in
FIFO if power is cycled.
EEPRM WRITE Noncritical fault. Check
calibration parameters for
bad data.
Replace microprocessor board.
FIELD LOSS Field current feedback low or
missing.
a. Check parameter X***:MOTOR I FLD
for proper motor/drive ratio.
b. Check field wiring.
c. Check for field jumpers at TB1 (3-5)
and (4-6).
d. Check fuses F1 and F2.
e. Check FLD I ECON percentage. (50%
recommended)
f. Check field ohms. (100-300 ohms)
g. Replace bridge interface board.
h. Replace power module.
FLD CTL LOS Field cannot reach setpoint. a. Check for proper MOTOR IFLD value.
b. Check for low line voltage causing field
firing into MIN ALPHA LIMIT.
c. Check for proper FLD MAX LMT
value.
d. Replace bridge interface board.
e. Replace microprocessor board.
FLT CLEARED Faults have been manually
cleared.
N/A
GATE POWER No gate power available or
gate power present when it
should be inhibited.
a. Replace bridge interface board.
b. Replace microprocessor board.
