10. TROUBLESHOOTING
Display Name Definition Cause Action
1. Servo amplifier faulty. Change the servo amplifier.
2. The power supply was turned on
and off continuously by overloaded
status.
The drive method is reviewed.
AL.45 Main circuit
device overheat
Main circuit device
overheat
3. Air cooling fan of servo amplifier
stops.
1. Exchange the cooling fan or the servo
amplifier.
2. Reduce ambient temperature.
1. Ambient temperature of servo
motor is over 40
(104
).
Review environment so that ambient
temperature is 0 to 40
(104
).
2. Servo motor is overloaded. 1. Reduce load.
2. Review operation pattern.
3. Use servo motor that provides larger
output.
AL.46 Servo motor
overheat
Servo motor
temperature rise
actuated the
thermal sensor.
3. Thermal sensor in encoder is
faulty.
Change servo motor.
1. Servo amplifier is used in excess
of its continuous output current.
1. Reduce load.
2. Review operation pattern.
3. Use servo motor that provides larger
output.
2. Servo system is instable and
hunting.
1. Repeat acceleration/
deceleration to execute auto tuning.
2. Change auto tuning response setting.
3. Set auto tuning to OFF and make gain
adjustment manually.
3. Machine struck something. 1. Review operation pattern.
2. Install limit switches.
4. Wrong connection of servo motor.
Servo amplifier's output terminals
U, V, W do not match servo
motor's input terminals U, V, W.
Connect correctly.
AL.50 Overload 1 Load exceeded
overload protection
characteristic of
servo amplifier.
5. Encoder faulty.
Checking method
When the servo motor shaft is
rotated with the servo off, the
cumulative feedback pulses do
not vary in proportion to the
rotary angle of the shaft but the
indication skips or returns midway.
Change the servo motor.
1. Machine struck something. 1. Review operation pattern.
2. Install limit switches.
2. Wrong connection of servo motor.
Servo amplifier's output terminals
U, V, W do not match servo
motor's input terminals U, V, W.
Connect correctly.
3. Servo system is instable and
hunting.
1. Repeat acceleration/deceleration to
execute auto tuning.
2. Change auto tuning response setting.
3. Set auto tuning to OFF and make gain
adjustment manually.
AL.51 Overload 2 Machine collision or
the like caused max.
output current to
flow successively for
several seconds.
Servo motor locked:
1s or more
During rotation:
2.5s or more
4. Encoder faulty.
Checking method
When the servo motor shaft is
rotated with the servo off, the
cumulative feedback pulses do
not vary in proportion to the
rotary angle of the shaft but the
indication skips or returns midway.
