Power Cable
Motor
Condition Reason Action Cause Correction
No operation Abnormal supply voltage Power supply Improper power supply Check power supply regularly
Condition Reason Action Cause Correction
No operation
Wire break
Repair or change cable
if broken
Strong force exerted
Firmly fix on cable support or
other equipment
(2 or more)
Use anti-vibration cable in
movable part.
Twisted, knotted Straighten twists and knots
Interference with other
equipment
Use fixed cable and avoid
outside interference
Overheating
Check cables, exchange if
overheating
Temperature rise due to
off-capacity
Adopt the proper cable
Binding cable used Do not use binding cable
Starting slow or no operation Off-capacity
Check cable diameter, replace
cable if diameter is too small
Voltage drop Adopt proper cable
Operation only in free load
(single phase)
1 wire break or
overheating
Refer to above break or overheating item
Movement did not correspond
with switch button (opposite)
Power line
connection error
Replace wires Wiring assembly error
Connect wire as per wiring
diagram
Condition Reason Action Cause Correction
No operation
Coil burning (above
2 phase)
Measure phase resistance value;
change motor if value is infinite.
Excessive current caused by
high or low voltage
Operate under rated voltage
Excessive current caused by
overload
Operate under rated voltage
Beyond short-term rating
and intermittent cycle rating
Short-term rating, intermittent
cycle rating, operate under
rated voltage
Avoid over-operation
Excessive current caused by
brake
Refer to brake
Lead wire break
(above 2 phase)
Measure phase resistance value;
change motor if value is infinite.
Lead wire broken in
assembly
Change motor coil
Vibration, drop
Avoid excessive bumping in
usage
Operation only in free load
(single phase state)
Coil burning
(1 phase only)
Measure phase resistance value;
change motor if value is infinite
Poor electric isolation
Ensure foreign matter does not
enter motor
Leading wire break
(1 phase only)
Measure phase resistance value;
change motor if value is infinite
Leading wire break in
assembly
Change motor coil
Vibration, drop Avoid excessive bumping
