 Panasonic servo drive fault code

Panasonic servo drive fault code

Since most Panasonic servo drive users do not know much about servo maintenance technology, many friends will think that the servo drive is faulty because of some simple servo parameter setting errors. This is an incorrect judgment. So, in response to this situation, we will take Panasonic A4 series servo drive maintenance as an example and summarize some Panasonic servo drive faults for your reference.

1: Alarm No. 11, control power supply under-voltage, control power inverter on P. The voltage between N is lower than the specified value. The internal circuit of the driver is defective, etc.

2: Alarm No. 12, control power supply overvoltage, control P on the power inverter. The voltage between N exceeds the specified value, the internal circuit of the driver is defective, etc.

3: Alarm No. 13, the main power supply is under-voltage, an instantaneous power outage occurs, the inrush current at the moment when the power is turned on causes a voltage drop, a phase loss or a defect in the internal circuit of the driver, etc.

4: Alarm No. 14, overcurrent or grounding error, the internal circuit of the driver or IGBT or other components are defective, or the motor cable (U, V, W) is short-circuited or grounded, or the motor is burned out.

5: Call the police on the 21st. The driver control board circuit is defective.

6: Alarm No. 60: The driver control board circuit is defective.

7: Unable to rotate forward and reverse: The driver control circuit is defective.

8: The driver does not display: The internal circuit or IGBT or other components of the driver are defective.

9: Alarm No. 99: The internal circuit of the driver is defective.

10: EEEEEE is displayed, the internal circuit of the driver is defective.
