Message Remedy
Check whether no disconnection, earth fault, or
short-circuit of the emergency stop input signal
exits. Then reboot the controller.
Check whether no disconnection, earth fault, or
short-circuit of the safeguard input signal exits.
Then reboot the controller.
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.
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.
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.
Check the Remote I/O setting value
Replace the battery for the CPU board
immediately. Keep the controller ON as long
as possible until the battery is replaced.
If normal voltage is not generated by 5V power
supply alone, replace the power supply.
If normal voltage is not generated by 24V
power supply alone, replace the power supply.
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.
Check whether the filter of the controller is not
clogged up. Replace the fan.
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.
If normal voltage is not generated by 3.3V of
Drive Unit 1 power supply alone, replace the
power supply.
If normal voltage is not generated by 5V of
Drive Unit 1 power supply alone, replace the
power supply.
If normal voltage is not generated by 24V of
Drive Unit 1 power supply alone, replace the
power supply.
