Maintenance 9. Troubleshooting
No. Message Remedy Note 1 Note 2
9001
Emergency stop circuit failure was detected.
Disconnection or other failure was found in
one of the redundant inputs.
Check whether no disconnection, earth fault, or
short-
circuit of the emergency stop input signal
exits. Then reboot the controller.
9002
Safeguard circuit failure was detected.
Disconnection or other failure was found in
one of the redundant inputs.
Check whether no disconnection, earth fault, or
short-circuit of the safeguard input signal exits.
Then reboot the controller.
9003
Initialization failure.
Failed to initialize the firmware.
This is likely because of the controller
hardware failure. Check the wiring is correct.
If the error is not cleared after the controller is
rebooted, contact us.
9004
Initialization failure.
Failed to initialize the DU.
Ckeck the DU power and the connection.
The number of set Drive Unit(s) disagrees with
the number of recognized Drive Unit(s).
Check the wirings of power supply and
between Control Unit and Drive Unit are
correct. If the error is not cleared after the
controller is rebooted, contact us.
9005
Initialization failure.
Failed to initialize the DU.
Ckeck the connection.
This is likely because of the Drive Unit
hardware failure. Check the wiring is correct.
If the error is not cleared after the controller is
rebooted, contact us.
9006
Initialization failure.
Failed to initialize the Remote I/O.
Check the Remote I/O setting.
Check the Remote I/O setting value
9011
Battery
voltage of the CPU board backup is
lower than the specified voltage. Replace the
CPU board battery.
Replace the battery for the CPU board
immediately. Keep the controller ON as long
as possible until the battery is replaced.
9012
5V input voltage for
CPU board is lower
than the specified voltage.
If normal voltage is not generated by 5V power
supply alone, replace the power supply.
9013
24 V input voltage for the motor brake,
encoder and fan is lower than the specified
voltage.
If normal voltage is not generated by 24V
power supply alone, replace the power supply.
9014
Internal temperature of the Controller is
higher than the specified temperature.
Stop the controller as soon as possible and
check whether the ambient temperature of the
controller is not high.
Check whether the filter is not clogged up.

Check whether the filter of the controller is not
clogged up. Replace the fan.

9017
Internal temperature of the Controller is
higher than the specified temperature.
Stop the controller as soon as possible and
check whether the ambient temperature of the
controller is not high.
Check whether the filter is not clogged up.
9021
DU1 3.3V input voltage for the board is
lower than the minimum allowed voltage.
If normal voltage is not generated by 3.3V of
Drive Unit 1 power supply alone, replace the
power supply.
9022
DU1 5V input voltage for the board is lower
than the minimum allowed voltage.
If normal voltage is not generated by 5V of
Drive Unit 1 power supply alone, replace the
power supply.
9023
DU1 24 V input voltage for the motor brake,
encoder and fan is lower than the specified
voltage.
If normal voltage is not generated by 24V of
Drive Unit 1 power supply alone, replace the
power supply.
