FAQ00243 of Programmable Controllers FAQ

If the power is interrupted for less than 10 ms when using a CQM1-PA203/-PA206/-PA216, the Programmable Controller will continue to run normally.
If the power is interrupted for more than 25 ms, the power interruption will be detected, the CPU Unit will stop, and the outputs will turn OFF.
A power interruption that lasts more than 10 ms but less than 25 ms may or may not be detected. Operation in this case cannot be predicted.

If the power is interrupted for longer than 5 ms when using a CQM1-PD026, the power interruption will be detected, the CPU Unit will stop, and the outputs will turn OFF.
