1. When in Trouble
Protective function (Detail of error code)
Causes
0 Voltage between P and N of the converter
portion of the control power supply has
fallen below the specified value.
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)
0
Voltage between P and N of the
converter portion of the control power
supply has exceeded the specified value
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)
0
Instantaneous power failure has occurred
between L1 and L3 for longer period than
the preset time with Pr6D (Main power
off detecting time) while Pr65 (LV trip
selection at the main power-off) is set
to 1. Or the voltage between P and N of
the converter portion of the main power
1
supply has fallen below the specified
value during Servo-ON.
1) Power supply voltage is low.
Instantaneous power failure has
occurred
2) Instantaneous power failure has
occurred.
3) Lack of power capacity...Power supply
voltage has fallen down due to inrush
current at the main power-on.
4) Phase lack...3-phase input driver has
been operated with single phase input.
5) Failure of servo driver (failure of the
circuit)
Measures
Measure the voltage between lines of
connector and terminal block (L1C - L2C) .
1) Increase the power capacity. Change the
power supply.
2) Increase the power capacity.
3) Replace the driver with a new one.
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 P
and B of the driver. Replace the external
resistor if the value is ∞.
3) Change to the one with specified
resistance and wattage.
4) Replace the driver with a new one.
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.
2) Set up the longer time to Pr5.09 (Main
power off detecting time). Set up each
phase of the power correctly.
3) Increase the power capacity. For the
capacity, refer to P.2-6, "Driver and List
of Applicable Peripheral Equipments" of
Preparation.
4) Connect each phase of the power supply
(L1, L2 and L3) correctly. For single phase,
100V and 200V driver, use L1 and L3.
5) Replace the driver with a new one.
