PROBLEM TO BE SOLVED: To improve the precision for detecting abnormality of a power source, to eliminate erroneous detection caused by load fluctuation, to improve the operability and to reduce the cost. SOLUTION: This controller is provided with a driver box 10 incorporating a switching power source circuit 40 and a driver circuit 50, and a control box 20 incorporating a control circuit 60. The output voltage of the circuit 40 is made the input voltage of the circuits 50 and 60. The circuit 50 drives the plural axes (axis 1, axis 2,..., axis N) of a robot based on a control signal from the circuit 60. The circuit 40 is provide with a power source abnormality detecting circuit 41 detecting the abnormality of an input power source to the circuit 40. |
