CAUSE
Trip command received
from fieldbus
Motor circuit fault due to
missing motor phase or
motor thermistor relay
(used in motor
temperature
measurement) fault.
Incorrect input power
and motor cable
connection (ie, input
power cable is
connected to drive motor
connection).
Loaded software is not
compatible.
Drive control board
overheated. Fault trip
limit is 95 °C.
STO (Safe torque off)
requested and it
functions correctly.
Parameter 3025 STO
OPERATION is set to
react with fault.
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.
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.

WHAT TO DO
Fault trip was caused by fieldbus. See
fieldbus user's manual.
Check motor and motor cable.
Check motor thermistor relay (if used).
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
WIRING FAULT.
Loaded software is not compatible
with the drive. Contact your local ABB
representative.
Check for excessive ambient
temperature.
Check for fan failure.
Check for obstructions in air flow.
Check the dimensioning and cooling
of cabinet.
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.
Check STO circuit cabling and
opening of contacts in STO circuit.
Check STO circuit cabling and
opening of contacts in STO circuit.
