PURPOSE:To facilitate the alteration of an operation control system of a controller for controlling a motor in response to an input signal by enabling to set the control system by a selection switch. CONSTITUTION:An input circuit 26 inputs a main circuit current detection signal IC, a zero phase current detection signal I0, state detections signals contact signals S by a starting operation switch, a stopping operation switch and a control system selection switch to a control circuit 28. The control circuit 28 logically judges with a command code stored in a memory 27 and an input data from an input circuit 26, and outputs a drive signal. An output circuit 29 controls the start and protection of a motor by the logic output from the circuit 28. In this manner, the configuration can be utilized, and the control system can be readily altered. |
