ABSTRACT:
A control unit for controlling a load is provided with a durable-time diagnosing device for generating integrated count data by integrating an operating time of the load, and for generating warning data for notification when the integrated count data has reached the durable time, and concurrently generating an interrupt command for prompting processing for stopping the driving of the load which approached a limit of its life. A notification is given to the effect that the load has approached a limit of its life when the integrated time has reached a durable time set in advance concerning the load. A method of predicting a failure of a load using the control units and a load controlling system using the control units are also disclosed.
