346 Fault tracing
0015 EXT FAULT 2
(9001)
0305 bit 14
(programmable fault
function 3004)
External fault 2 Check external devices for faults.
Check parameter 3004 EXTERNAL
FAULT 2 setting.
0016 EARTH FAULT
(2330)
0305 bit 15
(programmable fault
function 3017)
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 367.
Note: Disabling earth fault (ground
fault) may damage drive.
0017 UNDERLOAD
(FF6A)
0306 bit 0
(programmable fault
function
3013…3015)
Motor load is too low
due to eg release
mechanism in driven
equipment.
Check for problem in driven
equipment.
Check fault function parameters.
Check motor power against drive
power.
0018 THERM FAIL
(5210)
0306 bit 1
Drive internal fault.
Thermistor used for
drive internal
temperature
measurement is open
or short-circuited.
Contact your local ABB
representative.
0021 CURR MEAS
(2211)
0306 bit 4
Drive internal fault.
Current measurement
is out of range.
Contact your local ABB
representative.
0022 SUPPLY PHASE
(3130)
0306 bit 5
(programmable fault
function 3016)
Intermediate circuit DC
voltage is oscillating
due to missing input
power line phase or
blown fuse.
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 parameters.
0023 ENCODER ERR
(7301)
0306 bit 6
(programmable fault
function 5003)
Communication fault
between pulse
encoder and pulse
encoder interface
module or between
module and drive.
Check pulse encoder and its wiring,
pulse encoder interface module and
its wiring and parameter group 50
ENCODER
settings.
