Sony SI F209 SI E2000 SMD SMT Pick Up Nozzle CF00900 side b

Alarm Display: A. 410

Alarm Name: Undervoltage

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 supply voltage is 120 V or less.
Corrective Actions: The AC power supply voltage must be within the specified range.

Cause: The fuse of the SERVOPACK is blown out.
Corrective Actions: Replace the SERVOPACK.

Cause: The inrush current limit resistor is disconnected, and result in an abnormal power supply voltage or in an overload of the inrush current limit resistor.
Corrective Actions: Replace the SERVOPACK. (Check the power supply voltage, and reduce the number of times that the main circuit is turned ON or OFF.)

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

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

Cause: The AC power supply voltage was lowered, and large voltage drop occurred.
Corrective Actions: The AC power supply voltage must be within the specified range.

Cause: A temporary power failure occurred.
Corrective Actions: Clear and reset the alarm, and restart the operation.

Cause: The servomotor cable shorts to ground.
Corrective Actions: Repair or replace the servomotor cable.

Cause: The servomotor shorts to ground.
