5.2.1 Power-off Safety Precautions
Safety precautions
● The AC700 series controller will continue to operate normally for a certain period of time when an
instantaneous power failure occurs. Therefore, it may receive error signals from external devices affected by
the instantaneous power failure.
● Take fail-safe measures externally and monitor the power supply voltage on the external device side as
necessary. In addition, take safety measures in the user program.
5.2.2 Operations at Power-off
When a power failure occurs because the following power-off judgment time expires, the user program
is terminated.
After the power-off judgment time, even if the voltage is reset, the PLC still stops running, as shown in
the following figure.
