348 Fault tracing
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).
Fault can be
erroneously declared if
drive is faulty or input
power is delta
grounded system and
motor cable
capacitance is large.
Check input power connections.
0036 INCOMPATIBLE
SW
(630F)
0307 bit 3
Loaded software is not
compatible.
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.
