コード SRVO-136: DCLVAL alarm (G:%d A:%d)

Cause: The servo amplifier DC current (DC link voltage) is abnormally low. Remedy: The case of R-30iA Controller: • This alarm occurred when robot is moving. 1. Check the input voltage to the controller is within the rated voltage and no phase is lack. And check the setting of the transformer is correct. 2. It is possible that an instant disconnection of power source causes this alarm. Check whether an instant disconnection occurred. 3. Replace the E-stop unit. 4. Replace the servo amplifier. • If this alarm occurred before the magnetic contactor is turned on : 1. Check whether the circuit breaker in the emergency stop unit is OFF. If it is OFF, check the servo amplifier and the wiring between the servo amplifier and the emergency stop unit. If anything is abnormal, replace it. Else turn on the breaker. 2. Check the input voltage to the controller is within the rated voltage and no phase is lack. And check the setting of the transformer is correct. 3. Replace the E-stop unit. 4. Replace the servo amplifier. • In an auxiliary axis system and if this alarm occurred right after the EMERGENCY STOP button was pressed, check whether the auxiliary axis unit is installed correctly. • In the case of the Mate Controller, refer to the Mate Controller Maintenance Manual.
