PLC Operation for Power
Interruptions
z
Power Supply Voltage Drop
If the power supply voltage falls below the specified value (
8
5% of rated voltage) while the CPU Unit
is in RUN or MONITOR mode, operation will be stopped and all outputs will be turned OFF.
z
Detection of Momentary Power Interruptions
The system will continue to run if the momentary power interruption lasts less than 10 ms (2ms for
DC power supply). If power is interruped for longer than 10 ms (2ms for DC power supply), a
momentary power interruption will be detected or undetected. If the momentary power interruption is
detected, the CPU Unit will be stopped and outputs will be turned OFF.
z
Automatic Recovery
Operation is automatically restarted when the power supply voltage is restored.
