CAUSE
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.
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
Check input power connections.
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.
