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

4) Phase lack...3-phase input driver has
been operated with single phase input.
5) Failure of servo driver (failure of the circuit)
Measure the voltage between lines of
connector (L1, L2 and L3).
1) Increase the power capacity. Change the
power supply. Remove the causes of the
shutdown of the magnetic contactor or the
main power supply, then re-enter the power.
