Event name
Main Circuit Power Supply Undervoltage
(Undervoltage between positive and negative
terminals)
Event code
04AA 0000 hex
Description
If the Undervoltage Error Selection (3508 hex) is set to 1, a momentary power interruption occurred
between L1 and L3 for longer than the value specified for the Momentary Hold Time. The voltage between
the positive and negative terminals in the main power supply converter dropped below the specified value
while the Servo was ON.

Insufficient power supply capacity
Increase the power supply

The electromagnetic contactor in
the main circuit power supply was
tripped.
Eliminate the cause of the failure
of the electromagnetic contactor
on the main circuit power supply,
and then turn ON the power again.
Check the wiring of the main
circuit power supply.
A momentary power interruption
occurred.
Review the power supply
conditions and prevent momentary
power interruption. Alternatively,
increase the Momentary Hold
Time (3509 hex) setting.
Make sure that the power supply
conditions prevent momentary
power interruption.
A Servo Drive with 3-phase input
specifications was operated with
single-phase power supply.
Make sure that the phases of the
power supply are set correctly
before you connect them.
Make sure that the phases of the

The Servo Drive failed.
Replace the Servo Drive.
