CAUSE
External fault 2
Drive has detected
earth (ground) fault in
motor or motor cable.
Motor load is too low
due to eg release
mechanism in driven
equipment.
Drive internal fault.
Thermistor used for
drive internal
temperature
measurement is open
or short-circuited.
Drive internal fault.
Current measurement
is out of range.
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.
Communication fault
between pulse
encoder and pulse
encoder interface
module or between
module and drive.
WHAT TO DO
Check external devices for faults.
Check parameter 3004 EXTERNAL
FAULT 2 setting.
Check motor.
Check motor cable. Motor cable length
must not exceed maximum
specifications. See section
connection data on page 367.
Note: Disabling earth fault (ground
fault) may damage drive.
Check for problem in driven
equipment.
Check fault function parameters.
Check motor power against drive
power.
Contact your local ABB
representative.
Contact your local ABB
representative.
Check input power line fuses.
Check for input power supply
imbalance.
Check fault function parameters.
Check pulse encoder and its wiring,
pulse encoder interface module and
its wiring and parameter group
ENCODER settings.
