1.3 Handling methods for alarms/warnings
Check/action method
Check the ambient temperature of the servo motor, and if the temperature
exceeds the specified value, lower the ambient temperature.
Check the effective load ratio.
If the effective load ratio exceeds 100 %, reduce the load or review the
operation pattern.
Replace the servo motor.
Check/action method
Check the ambient temperature of the servo motor. If the ambient temperature
exceeds the specified value, lower the ambient temperature.
Check the effective load ratio.
If the effective load ratio exceeds 100 %, reduce the load or review the
operation pattern.
Check/action method
Check if the servo motor thermistor wire is connected.
Check for disconnection in the servo motor thermistor wire. If the servo motor
thermistor wire is disconnected, repair the wire.
Check/action method
Replace the servo amplifier.
Check/action method
Check the effective load ratio.
If the effective load ratio is high, reduce the load or review the operation
pattern. Otherwise, replace the servo motor with a larger-capacity servo motor.
