≥ 4

• The parameter that is written in the encoder

is incorrect.

• A SERVOPACK board fault occurred.

• Select the proper combination of SERVOPACK

and servomotor capacities.

A.040 Parameter

Setting Error

• Occurred when the

control power supply was

turned ON.

• The SERVOPACK and servomotor capacities

do not match each other.

• The SERVOPACK EEPROM and the related

circuit are faulty.

• Select the proper combination of SERVOPACK

and servomotor capacities.

A.041 Dividing Pulse

Output Setting

Error

the setting range and does not satisfy the

setting conditions.

• Set Pn212 to the correct value.

A.100 Overcurrent • Occurred when the control

power supply was turned

ON.

• The overload alarm has been reset by turning

OFF the power too many times.

• The connection is faulty between the

SERVOPACK board and the thermostat switch.

• The SERVOPACK board fault occurred.

• Change the method to reset the alarm

• Replace the SERVOPACK.

• Occurred when the main

circuit power supply was

turned ON or when an

overcurrent occurred while

the servomotor was

running.

• The connection between grounding and U, V,

or W is incorrect.

• The grounding line has contact with other

terminals.

• A short circuit occurred between the grounding

and U, V. or W of the servomotor cable.

• A short circuit occurred between phase U. V, or

W of the servomotor.

• The wiring of the regenerative resistor is

incorrect.

• A short circuit occurred between the grounding

and U, V, or W of the SERVOPACK.

• A SERVOPACK fault occurred (current

feedback circuit, power transistor or board fault).

• A short circuit occurred between the grounding

and U, V, W of the servomotor.

• A short circuit occurred between the grounding

and U, V, W of the servomotor.

• A fault occurred in the dynamic brake circuit.

• The dynamic brake was activated too

frequently, so a DB overload alarm occurred.

• The overload alarm has been reset by turning

OFF the power too many times.

• The overload or regenerative power exceeds

the regenerative resistor's capacity.

• The direction or the distance of the

SERVOPACK to other devices is incorrect.

Heat radiation of the panel or heat around the

panel occurred.

• A SERVOPACK fan fault occurred.

• A SERVOPACK fault occurred.

• Check and then correct the wiring.

• Repair or replace the servomotor cable.

• Check and then correct the wiring.

• Replace the SERVOPACK.

• Replace the servomotor.

• Replace the SERVOPACK, and reduce the load,

or reduce the number of rotations used.

• Replace the SERVOPACK, and reduce the DB

operation frequency.

• Change the method to reset the alarm.

• Reconsider the load and operation conditions.

• The ambient temperature for the SERVOPACK

must be 55°C or less.

• Replace the SERVOPACK.

A.300 Regeneration

Error Detected

• Occurred when the control

power supply was turned

ON.

• A SERVOPACK board fault occurred. • Replace the SERVOPACK.

circuit power supply turned

ON.

• Pn600 is set to a value other than "0" for a

servomotor of 400 W or less, and an external

regenerative resistor is not connected.
