摘要： A control apparatus for controlling an industrial machine includes a deterioration diagnostic unit that has a diagnostic function, which is repeatedly executed at predetermined timing, for diagnosing deterioration of each component of the industrial machine and outputs an alarm signal in response to deterioration equal to or more than a predetermined level in each component, an alarm control unit that outputs a stop command to the industrial machine based on the alarm signal and informs that the industrial machine is in an alarm stop state, and a cancellation operation receiving unit that receives the cancellation operation for cancelling the alarm stop state regardless of deterioration of each component. The deterioration diagnostic unit cancels the alarm stop state brought on by the diagnostic function based on the cancellation operation, and allows the industrial machine to operate until the diagnostic function is executed next.

摘要： A power supply according to the present disclosure includes: a step-down circuit which has at least one pair of positive/negative step-down switching elements; at least one pair of positive/negative inductors to which voltage is applied via the step-down switching element, and one pair of positive/negative output capacitors which are connected in series and charged by electrical current passing through the inductor, and steps down input voltage and then outputs; an inverse-conversion circuit which has a plurality of inverse-conversion switching elements, and inverse-converts output voltage of the step-down circuit into alternating current; and a control circuit which controls switching of the plurality of step-down switching elements so that the output voltage of the step-down circuit becomes a desired voltage.
