Table 2.14 Servo Amplifier Error List (2000 to 2799)
Error Cause
Description
• The power supply voltage is less than
160 VAC. (320VAC or less for 400VAC
series servo)
• A momentary power, interruption of
15ms or longer has occurred.
• The power supply voltage dropped, for
example when motion control started,
due to insufficient power capacity.
• Servo amplifier SRAM is faulty.
• Servo amplifier EPROM check sum
error.
• Servo amplifier clock fault.
• Servo amplifier hardware fault
• Servo system CPU hardware fault
• Servo amplifier EEPROM fault
• Fault in communication with the
encoder
• Faulty device in the servo amplifier
PCB.
• Servo amplifier flash ROM check sum
error
• Fault in communication with the
encoder
• The servo-on (SON) signal turned ON
when the ready signal (RD) of the
converter is OFF.
1. Bus voltage is OFF.
2. Alarm occurring in converter.
• U, V, or W of the servo amplifier output
grounded
• The voltage of the supercapacitor inside
the absolute encoder has dropped.
• The battery voltage is low.
• Failure of battery cable or battery.
(Home position return must be re-
executed after clearing the error.)

Corrective Action
• Measure the input voltage (R, S, T) with a
voltmeter.
• Monitor with an oscilloscope to check whether a
momentary power interruption has occurred.
• Review the power capacity.
• Replace the servo amplifier.
• Replace the servo amplifier.
• Replace the servo amplifier.
• Replace the servo system CPU.
• Replace the servo amplifier.
• Check if the connector of the encoder cable is
loose.
• Replace the servomotor.
• Replace the encoder cable.
• Replace the servo amplifier.
• Replace the servo amplifier.
• Check if the connector of the encoder cable is
loose.
• Replace the servomotor.
• Replace the encoder cable.
• Remove the cause of the converter alarm.
Deactivate the alarm.
• Check if the servo motor and cable have been
grounded.
• Correct the grounding.
• Replace the servomotor.
• Turn the power ON for 2 to 3 minutes to charge
the supercapacitor, switch the power OFF then
ON again, and execute a zeroing.
• Turn the servo amplifier power OFF, then
measure the battery voltage.
• Replace the servo amplifier battery.
