Condion Reason Acon Cause Correcon
No operaon Abnormal supply voltage Power supply Improper power supply Check power supply regularly
Condion Reason Acon Cause Correcon
No operaon
Wire break
Repair or change cable
if broken
Strong force exerted
Firmly x on cable support or
other equipment
(2 or more)
Use an-vibraon cable in
movable part.
Twisted, knoed Straighten twists and knots
Interference with other
equipment
Use xed cable and avoid
outside interference
Overheang
Check cables, exchange if
overheang
Temperature rise due to
o-capacity
Adopt the proper cable
Binding cable used Do not use binding cable
Starng slow or no operaon O-capacity
Check cable diameter, replace
cable if diameter is too small
Voltage drop Adopt proper cable
Operaon only in free load
(single phase)
1 wire break or
overheang
Refer to above break or overheang item
Movement did not correspond
with switch buon (opposite)
Power line
connecon error
Replace wires Wiring assembly error
Connect wire as per wiring
diagram
Condion Reason Acon Cause Correcon
No operaon
Coil burning (above
2 phase)
Measure phase resistance value;
change motor if value is innite.
Excessive current caused by
high or low voltage
Operate under rated voltage
Excessive current caused by
overload
Operate under rated voltage
Beyond short-term rang
and intermient cycle rang
Short-term rang, intermient
cycle rang, operate under
rated voltage
Avoid over-operaon
Excessive current caused by
brake
Refer to brake
Lead wire break
(above 2 phase)
Measure phase resistance value;
change motor if value is innite.
Lead wire broken in
assembly
Change motor coil
Vibraon, drop
Avoid excessive bumping in
usage
Operaon only in free load
(single phase state)
Coil burning
(1 phase only)
Measure phase resistance value;
change motor if value is innite
Poor electric isolaon
Ensure foreign maer does not
enter motor
Leading wire break
(1 phase only)
Measure phase resistance value;
change motor if value is innite
Leading wire break in
assembly
Change motor coil
Vibraon, drop Avoid excessive bumping
