Remedy
Check whether the filter is not clogged
up. If the warning is not cleared after
the controller is rebooted, replace the
fan.
Check whether the filter is not clogged
up. If the warning is not cleared after
the controller is rebooted, replace the
fan.
Stop the controller as soon as possible
and check whether the

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.
Stop Drive Unit 1 as soon as possible
and check whether the
temperature of Drive Unit 1 is not high.
Check whether the filter is not clogged
up.
