Fault tracing 363
0030 FORCE TRIP
(FF90)
0306 bit 13
Trip command received
from fieldbus
Fault trip was caused by fieldbus. See
fieldbus user’s manual.
0034 MOTOR PHASE
(FF56)
0306 bit 14
Motor circuit fault due to
missing motor phase or
motor thermistor relay
(used in motor
temperature
measurement) fault.
Check motor and motor cable.
Check motor thermistor relay (if used).
0035 OUTP WIRING
(FF95)
0306 bit 15
(programmable
fault function
3023)
Incorrect input power
and motor cable
connection (ie, input
power cable is
connected to drive motor
connection).
Possible power wiring error detected.
Check that input power connections
are not connected to drive output.
Fault can be declared if input power is
delta grounded system and motor
cable capacitance is large. This fault
can be disabled by parameter 3023
WIRING FAULT.
0036 INCOMPATIBLE
SW
(630F)
0307 bit 3
Loaded software is not
compatible.
Loaded software is not compatible
with the drive. Contact your local ABB
representative.
0037 CB OVERTEMP
(4110)
0305 bit 12
Drive control board
overheated. Fault trip
limit is 95 °C.
Check for excessive ambient
temperature.
Check for fan failure.
Check for obstructions in air flow.
Check the dimensioning and cooling
of cabinet.
0044 SAFE TORQUE
OFF
(FFA0)
0307 bit 4
STO (Safe torque off)
requested and it
functions correctly.
Parameter 3025 STO
OPERATION is set to
react with fault.
If this was not expected reaction to
safety circuit interruption, check
cabling of safety circuit connected to
STO terminals X1C.
If different reaction is required, change
value of parameter 3025 STO
OPERATION.
Reset fault before starting.
0045 STO1 LOST
(FFA1)
0307 bit 5
STO (Safe torque off)
input channel 1 has not
de-energized, but
channel 2 has. Opening
contacts on channel 1
might have been
damaged or there is a
short-circuit.
Check STO circuit cabling and
opening of contacts in STO circuit.
0046 STO2 LOST
(FFA2)
0307 bit 6
STO (Safe torque off)
input channel 2 has not
de-energized, but
channel 1 has. Opening
contacts on channel 2
might have been
damaged or there is a
short-circuit.
Check STO circuit cabling and
opening of contacts in STO circuit.
