Inverter: abnormal control power supply

What does Blinking mean?

An abnormality is detected in the inverter's control power supply. This can stem from a failure in the JF* connector or cable, or issues with the motor itself or the SVM. This fault prevents stable operation of the inverter.

• Connector or cable (JF*) failure.
• Motor failure.
• SVM failure.

1. 1

   Inspect the JF* connector for secure connection and damage.

2. 2

   Check the JF* cable for continuity and shorts.

3. 3

   Measure the control power supply voltage to the inverter.

4. 4

   Verify motor winding resistance values against specifications.
