EXT FAULT 1
(programmable
fault function,
parameter 3003
EXTERNAL
FAULT 1)
Check external devices for faults.
Check fault function parameter setting.
EXT FAULT 2
(programmable
fault function,
parameter 3004
EXTERNAL
FAULT 2)
Check external devices for faults.
Check fault function parameter setting.
EARTH FAULT
(programmable
fault function,
parameter 3017
EARTH FAULT)
Drive has detected earth (ground)
fault in motor or motor cable.
Check motor.
Check motor cable. Motor cable length must not
exceed maximum specifications. See section Motor
connection data on page 144.
Note: Disabling earth fault (ground fault) may
damage drive.
UNDERLOAD
(programmable
fault function,
parameters
3013...3015)
Motor load is too low due to, for
example, release mechanism in
driven equipment.
Check for problem in driven equipment.
Check fault function parameter settings.
Check motor power against drive power.
Drive internal fault. Thermistor
used for drive internal temperature
measurement is open or
short-circuited.
Contact your local ABB representative.
Drive internal fault. Current
measurement is out of range.
Contact your local ABB representative.
INPUT PHASE
LOSS
(programmable
fault function,
parameter 3016
SUPPLY PHASE)
Intermediate circuit DC voltage is
oscillating due to missing input
power line phase or blown fuse.
Fault trip occurs when DC voltage
ripple exceeds 14% of nominal DC
voltage.
Check input power line fuses.
Check for input power supply imbalance.
Check fault function parameter setting.
Contact your local ABB representative.
Internal configuration file error
Contact your local ABB representative.
OUTP WIRING
(programmable
fault function,
parameter 3023
WIRING FAULT)
Incorrect input power and motor
cable connection (that is 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.
Loaded software is not
compatible.
Contact your local ABB representative.
Corrupted Serial Flash chip file
system
Contact your local ABB representative.
Active macro file missing from
Serial Flash chip
Contact your local ABB representative.
