04A80000 hex Control
Power Sup-
ply Under-
voltage
The voltage
between the posi-
tive and negative
terminals in the
control power sup-
ply converter
dropped below the
specified value.
• Power supply undervoltage. Or,
the power supply voltage
dropped because there was
inrush current when the main
power supply was turned ON.
• A momentary power interrup-
tion occurred.
• The Servo Drive failed.

04A90000 hex Overvoltage The power supply
voltage exceeded
the allowable input
voltage range.
• The voltage between the posi-
tive and negative terminals in
the control power supply con-
verter exceeded the specified
value.
• The voltage was suddenly
increased by the phase
advance capacitor or the unin-
terruptible power supply (UPS).
• The Regeneration Resistor wir-
ing is broken.
• The External Regeneration
Resistor is not suitable.
• The Servo Drive failed.
S Same as
above.
04AA0000 hex Main Circuit
Power Sup-
ply Under-
voltage
(Undervolt-
age between
positive and
negative ter-
minals)
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 posi-
tive and negative
terminals in the
main power supply
converter dropped
below the specified
value while the
Servo was ON.
• Insufficient power supply
capacity
• The electromagnetic contactor
in the main circuit power supply
was tripped.
• A momentary power interrup-
tion occurred.
• A Servo Drive with 3-phase
input specifications was oper-
ated with a single-phase power
supply.
• The Servo Drive failed.
S Same as
above.

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 posi-
tive and negative
terminals in the
main power supply
converter dropped
below the specified
value while the
Ser
vo wa
s ON.
• Insufficient power supply
capacity
• The electromagnetic contactor
in the main circuit power supply
was tripped.
• A momentary power interrup-
tion occurred.
• A Servo Drive with 3-phase
