Fault tracing 361
0012 MOTOR STALL
(7121)
0305 bit 11
(programmable
fault function
3010…3012)
Motor is operating in stall
region due to, eg,
excessive load or
insufficient motor power.
Check motor load and drive ratings.
Check fault function parameters
3010...3012.
0014 EXT FAULT 1
(9000)
0305 bit 13
(programmable
fault function
3003)
External fault 1 Check external devices for faults.
Check parameter 3003 EXTERNAL
FAULT 1 setting.
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 385.
Note: Disabling earth fault (ground
fault) may damage drive.
Drive internal fault. Internal short-circuit may cause earth
fault indication. This has happened if
fault 0001 appears after disabling the
earth fault. Replace the 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
3010...3012.
Check motor power against drive
power.
0018 THERM FAIL
(5210)
0306 bit 1
Temperature of the drive
exceeds the operating
level of the thermistor.
Check that the ambient temperature is
not too low.
Drive internal fault.
Thermistor used for drive
internal temperature
measurement is open or
short-circuited
Replace the drive.
0021 CURR MEAS
(2211)
0306 bit 4
Drive internal fault.
Current measurement is
out of range.
Replace the drive.
