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 (in
vector control) or 2007
MINIMUM FREQ and
2008 MAXIMUM
FREQ (in scalar
control).
Check minimum/maximum frequency
settings.
Check adequacy of motor braking
torque.
Check applicability of torque control.
Check need for brake chopper and
resistor(s).
0027 CONFIG FILE
(630F)
0306 bit 10
Internal configuration
file error
Contact your local ABB
representative.
0028 SERIAL 1 ERR
(7510)
0306 bit 11
(programmable fault
function 3018, 3019)
Fieldbus
communication break
Check status of fieldbus
communication. See chapter Fieldbus
control with embedded fieldbus on
page 301, chapter Fieldbus control
with fieldbus adapter on page 325 or
appropriate fieldbus adapter manual.
Check fault function parameter
settings.
Check connections.
Check if master can communicate.
0029 EFB CON FILE
(6306)
0306 bit 12
Configuration file
reading error
Contact your local ABB
representative.
0030 FORCE TRIP
(FF90)
0306 bit 13
Trip command
received from fieldbus
See appropriate communication
module manual.
0034 MOTOR PHASE
(FF56)
0306 bit 14
Motor circuit fault due
to missing motor
phase or motor
thermistor relay (used
in motor temperature
measurement) fault.
Check motor and motor cable.
Check motor thermistor relay (if used).
