We have developed a new control system of a magnet power supply to work with a Programmable Logic Controller (PLC). The control PLC handles the status of the interlock signals between a power supply and a magnet, and monitors the output voltage and the current. The PLC also controls a programmable reference voltage to regulate the output current. In addition, we have been developing an automatic orbit-correction program with the control system of the magnet power supply. The previous data of the beam profile monitors located on the upstream side of the beam dump and the temperature distribution on the beam dump show a possibility of the automatic correction of the beam orbit to the beam dump. The optimized current for the horizontal steering magnet was calculated from the horizontal displacement of the proton beam measured with the beam profile monitors. This paper reports the current status of the power supply control system which can automatically correct the horizontal beam position at the beam dump.
