Error Content
Main circuit device overheat
• Main circuit device overheat
Servo motor overheat
• A servo motor temperature rise actuated the
thermal sensor.
Cooling fan alarm
• The cooling fan of the servo amplifier
stopped.
• The rotation speed of the fan fell below the alarm
level.
Overload 1
The load exceeded the overload
characteristics of the servo amplifier.
Overload 2
• A machine collision or other simiar factor has
caused the max. output
continuously for several seconds.
Servo motor
- Locked :1s or more
- During rotation :2.5s or more
• Replace the servo amplifier.
• Review the drive method.
• Review the environment so that the ambient
temperature is within the range 0 to 55°C.
• Use within the specification range.
• Review the environment so that the ambient
temperature is within the range 0 to 40°C.
• Reduce the load.
• Review the operation pattern.
• Use a servo motor that provides larger output.
• Replace the servo motor.
• Replace the cooling fan of the servo amplifier.
