ABSTRACT:
An inverter has a measuring part that measures an operating time such as the time interval from when a command to start a specified operation by an associated system until a signal indicating the completion of the operation is received. A comparing part compares this measured operating time with a threshold value stored in a memory and an abnormal condition is reported to a host system, depending on the result of the comparison.
