Main causes:

1. There is a connection problem between the power module and the servo board.

2. An open circuit in the motor power wiring (U, V, W phases) or a poor connector connection.

3. A short-circuit current flows.

4. The IPM (intelligent power module) control power supply voltage (+15V, upper side) has decreased.

5. The temperature of the IGBT chip inside the IPM (intelligent power module) has risen.

6. A problem with the IPM (intelligent power module).

7. A problem with the power supply unit control board or power supply unit power board.

Countermeasures:

1. Check the installation of the servo board.

2. Check the motor power wiring connections.

3. Check the motor U-phase, V-phase, and W-phase wiring for short circuits or ground faults.

4. Check the harness and connector connections of the servo amplifier unit.

5. Check the cooling devices (cooling fans, etc.) and fan operating time settings.

6. Replace the servo amplifier unit.

7. Replace the power supply unit.

[NOTE]
This error may indicate a serious fault. Therefore, do not reset the error immediately; investigate the cause carefully according to the countermeasures. If the error does not clear immediately, wait approximately one minute and reset the error again.
