Warning Warnng Name Status Cause Remedy

A.900 Position Error

Pulse Overflow

• Occurred during operation. • A SERVOPACK board fault occurred.

• Wiring is incorrect or the contact of

servomotor U, V, and W is faulty.

• The SERVOPACK gain adjustment is

improper.

• The position reference pulse frequency is too

high.

• Setting of the parameter Pn520 (Position

Error Pulse Alarm Level) is improper.

• The servomotor specifications do not meet

the load conditions (torque, moment of inertia)

• Replace the SERVOPACK.

• Correct the servomotor wiring.

• Correct the encoder wiring.

• Increase the speed loop gain (Pn100) and

position loop gain (Pn102).

• Decrease slowly the position reference pulse

frequency.

• Apply the smoothing function.

• Adjust the electronic gear ratio.

• Set the parameter Pn520 to a value other than

"0".

• Reconsider and correct the load and servomotor

capacity.

A.901 Position Error

Pulse Overflow at

Servo ON

• Occurs when the servo

was ON.

• Errors accumulated excessively in servo OFF

status

• With the setting not to clear the errors while

the servo is OFF, the servomotor was running.

• Do not run the servomotor in servo OFF status.

• Make the setting so that the errors are cleared in

servo OFF status.

• Adjust the detection level.

A.910 Overload :

Warning for the

alarms A710 and

A720

• Occurs when the servo

was ON.

• The servomotor did not

run with a reference input.

• Occurred during operation.

• Wiring is incorrect and the contact in

servomotor wiring is faulty.

• Wiring is incorrect and the contact in encoder

wiring is faulty.

• A SERVOPACK fault occurred.

• Servomotor wiring is incorrect and the contact

is faulty.

• Encoder wiring is incorrect and the contact is

faulty.

• The starting torque exceeds the maximum

torque.

• A SERVOPACK fault occurred.

• The effective torque exceeds the rated torque.

• Temperature in the SERVOPACK panel is

high.

• A SERVOPACK fault occurred.

• Correct the servomotor wiring.

• Correct the encoder wiring.

• Replace the SERVOPACK.

• Correct the servomotor wiring.

• Correct the encoder wiring.

• Reconsider the load and operation conditions.

Or, check the servomotor capacity.

Warning Display and Troubleshooting

Warning Warning Name Status Cause Remedy

A.911 Vibration • Occurred during normal

operation.

• Servo Amplifier gain is improper.

• The moment of inertia ratio (Pn103) is greater

than the actual value, or fluctuates excessively.

• To adjust the gain, decrease the speed loop gain

(Pn100) and position loop gain (Pn101), and

increase the filter time constants such as torque

reference filter (Pn401).

• Change the moment of inertia ratio (Pn103)

to an appropriate value.

• Regenerative energy is excessive.

• Replace the SERVOPACK.

• Check the regenerative resistor capacity, or

reconsider the load and operation conditions.

• Correct the setting of parameter Pn600.

• Replace the SERVOPACK.

• Check the regenerative resistor capacity, or

reconsider the load and operation conditions.
