Alarm Display: A. 400. Alarm Name: Overvoltage on Sony SI-F209

Sony SI F209 SI E2000 SMD SMT Pick Up Nozzle CF20150

Alarm Display: A. 400

Alarm Name: Overvoltage

1. Situation at Alarm Occurrence: Occurred when the control power supply was turned ON.

Cause: A SERVOPACK board fault occurred.
Corrective Actions: Replace the SERVOPACK.

2. Situation at Alarm Occurrence: Occurred when the main circuit power supply was turned ON.

Cause: The AC power voltage is 290 V or more.
Corrective Actions: The AC power voltage must be within the specified range.

Cause: A SERVOPACK fault occurred.
Corrective Actions: Replace the SERVOPACK.

3. Situation at Alarm Occurrence: Occurred during normal operation.

Cause: Check the AC power voltage. (check if there is no excessive voltage change.)
Corrective Actions: The AC power voltage must be within the specified range.

Cause: The motor speed is high and load moment of inertia is excessive, resulting in insufficient regenerative capacity.
Corrective Actions: Check the load moment of inertia and minus load specifications. Reconsider the load and operation conditions.

Cause: A SERVOPACK fault occurred.
Corrective Actions: Replace the SERVOPACK.

4. Situation at Alarm Occurrence: Occurred at servomotor deceleration.

Cause: The motor speed is high, and the load moment of inertia is excessive.
Corrective Actions: Reconsider the load and operation conditions.
