12 Troubleshooting

12-3 Errors

If the Servo Drive detects an abnormality, it outputs an error (/ERR), turns OFF the power drive circuit,
and displays the error number (main and sub) on the front panel.
Precautions for Correct Use
• Refer to 12-5-1 Troubleshooting Using Error Displays on page 12-14 for information on trou-
bleshooting.
• You can reset the error by turning OFF the power supply and then ON again, or executing the
error reset command via EtherCAT communications or on the Sysmac Studio. Be sure to
remove the cause of the error first.
• Some errors are reset only by turning the power supply OFF then ON again. For details, refer
to 12-3-1 Error List on page 12-10.
• If nothing is displayed on the 7-segment display even when the control power supply is ON, it
indicates that the internal MPU is malfunctioning. If you find this symptom, cut off the power
supply immediately.
