官方故障排除步驟
Cause: The servo amplifiers were not found at the power up sequence. Remedy: 1. When any LED on the servo amplifier does not light with the power supply of the controller turned on, the power is not supplied to the servo amplifier. Confirm whether there is neither disconnecting nor loosening in each connector on the servo amplifier and the emergency stop unit. 2. Turn off the power of the controller, disconnect the pulse coder cable JF1,JF2 from the servo amplifier and turn on the power of the controller again. If this alarm does not occur, the pulse coder cable may have ground fault.(The LED of the servo amplifier may display blinking '-' in this case.) 3. Replace the servo amplifier for auxiliary axis. 4. Replace the 6-Axis servo amplifier. 5. Replace the optical fiber cable. 6. Replace the servo card or the auxiliary axis servo card.
