(Undervoltag

terminals)
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 (3509 hex).
Alternatively, the voltage between the
positive and negative terminals in the
main power supply converter dropped
below the specified value while the servo
was ON. Measure the voltage between the
connector (L1, L2, and L3) lines.
• The power supply voltage is low. • Increase the power supply voltage.
Change the power supply. Eliminate the
cause of the failure of the
electromagnetic contactor on the main
circuit power supply, and then turn ON
the power again.

detected)
• A momentary power interruption
occurred. • Check the setting of the Momentary
Hold Time (3509 hex). Set each phase
of the power supply correctly.
• Insufficient power supply capacity: the
power supply voltage dropped because
there was inrush current when the main
power supply was turned ON. • Increase the power supply capacity.
• Phase-failure: a Servo Drive with
3-phase input specifications was
operated with single-phase power
supply. • Connect each phase (L1, L2, and L3) of
the power supply correctly. Use L1 and
L3 for single-phase 100 V and
single-phase 200 V.
• The Servo Drive is faulty (circuit fault). • Replace the Servo Drive.
Error No.
