(PN) Instantaneous power failure has occurred
between L1 and L3 for longer period than
the preset time with Pr5.09 (Main power off
detecting time) while Pr5.08 (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 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)
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.2-18, "List of Applicable
Peripheral Equipments to Driver" of
Preparation.
4) Connect each phase of the power supply
(L1, L2 and L3) correctly. For single phase,
100 V and 200 V driver, use L1 and L3.
5) Replace the driver with a new one.

protection
Current through the converter portion has
exceeded the specified value.
1) Failure of servo driver (failure of the
circuit, IGBT or other components)
2) Short of the motor wire (U, V and W)
3) Earth fault of the motor wire
4) Burnout of the motor
5) Poor contact of the motor wire.
6) Welding of contact of dynamic braking
relay due to frequent servo ON/OFF
operations.
7) Timing of pulse input is same as or
earlier than Servo-ON.
8) Blowout of thermal fuse due to
overheating dynamic brake circuit. (Only F )
1) Turn to Servo-ON, while disconnecting the
motor. If error occurs immediately, replace
with a new driver.
2) Check that the motor wire (U, V and W) is
not shorted, and check the branched out
wire out of the connector. Make a correct
wiring connection.
3) Measure the insulation resistance between
motor wires, U, V and W and earth wire. In
case of poor insulation, replace the motor.
4) Check the balance of resister between
each motor line, and if unbalance is found,
replace the motor.
5) Check the loose connectors. If they are, or
pulled out, fix them securely.
6) Replace the servo driver. Do not use
Servo-ON/Servo-OFF as a means of
staring/stopping the operation.
7) Enter the pulses 100 ms or longer after
Servo-ON.
8) Replace the driver.

Caution
Note
・
Confirmation work is that checking the charge lamp is turned off after the power supply turn off.
・
When protective function marked with * in the protective function table is activated, it cannot
be disabled by the alarm clear input (USB conmmunication(PANATERM) or RTEX alarm
clear commond). To return to the normal operation, turn off power, and then turn on power
again,or use soft reset commond by RTEX conmmunication.
