1) Power supply voltage is low.
Instantaneous power failure has
occurred
2) Lack of power capacity...Power supply
voltage has fallen down due to inrush
current at the main power-on.
3)
Failure of servo driver (failure of the circuit)
Measure the voltage between lines of
connector and terminal block.

1) Power supply voltage has exceeded
the permissible input voltage. Voltage
surge due to the phase-advancing
capacitor or UPS (Uninterruptible
Power Supply) have occurred.
2) Disconnection of the regeneration
discharge resistor
3) External regeneration discharge
resistor is not appropriate and could
not absorb the regeneration energy.
4) Failure of servo driver (failure of the
circuit)
Measure the voltage between lines of
connector (L1, L2 and L3).
1) Enter correct voltage. Remove a phase-
advancing capacitor.
2) Measure the resistance of the external
resistor connected between terminal B1
- B2 of the driver. Replace the external
