Fault tracing
280
0017 UNDERLOAD
(FF6A)
0306 bit 0
(programmable fault
function
3013 ... 3015 )
Motor load is too low due to e.g.
release mechanism in driven
equipment. Check for problem in driven equipment.
Check fault function parameters.
Check motor power against unit 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.
0024 OVERSPEED
(7310)
0306 bit 7
Motor is turning faster than
highest allowed speed due to
incorrectly set minimum/
maximum speed, insufficient
braking torque or changes in
load when using torque
reference.
Operating range limits are set
by parameters
2001 MINIMUM
SPEED and 2002 MAXIMUM
SPEED (with vector control) or
2007 MINIMUM FREQ and
2008 MAXIMUM FREQ (with
scalar control).
Check minimum/maximum speed settings.
Check adequacy of motor braking torque.
Check applicability of torque control.
Check need for brake chopper and resistor(s).
0026 DRIVE ID
(5400)
0306 bit 9
Internal drive ID fault Contact your local ABB representative.
0027 CONFIG FILE
(630F)
0306 bit 10
Internal configuration file error Contact your local ABB representative.
