F30001: IGBT or internal chip overcurrent

What does F30001 mean?

This fault indicates an overcurrent condition within the IGBT or internal chip. It can appear when the main power supply is connected or during motor operation.

• Short-circuited connections between different phases (U, V, W, PE)
• Disconnected U, V, or W phase
• Incorrect or bad grounding connection
• Damaged motor insulation or damaged drive

Click steps to track your progress.

1. 1

   Check the U, V, W, and PE connections on the drive for any short circuits between phases, disconnected phases, incorrect grounding, or damaged wires.

2. 2

   Power on the system again and observe if the fault still exists after verification.

3. 3

   If the fault persists, check the insulation of the motor for damage. Consider changing the motor if damaged.

4. 4

   Power on the system again and observe if the fault still exists after motor check.

5. 5

   If the fault still exists after these inspections, replacement and maintenance are necessary as the drive is likely damaged.
