CONTROL SYSTEM AND POWER SUPPLY UNIT

This power supply unit of a control system outputs a notification signal to a calculation unit when a time in which an input voltage becomes smaller than a threshold voltage exceeds a prescribed first measurement time. When detecting that a predetermined second measurement time has elapsed after the...

Beschreibung
Zusammenfassung:	This power supply unit of a control system outputs a notification signal to a calculation unit when a time in which an input voltage becomes smaller than a threshold voltage exceeds a prescribed first measurement time. When detecting that a predetermined second measurement time has elapsed after the notification signal has been received, the calculation unit outputs an instruction signal instructing the execution of a process before a stop in preparation for a prescribed stop of power supply, and executes the process before the stop in place of the current process. Settings of the threshold voltage and the second measurement time are configured to be changeable by means of an external operation.
