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.
Check 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.
Check 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.

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.
