PROBLEM TO BE SOLVED: To provide an auxiliary stabilizing circuit for main circuit power source with which a DC power source can be stably supplied against the load fluctuation of servo drive device by adding a simple low-cost circuit even when using the DC output voltage of converter as the main circuit power source of plural servo drive devices. SOLUTION: Concerning this circuit, an auxiliary stabilizing circuit 105 for main circuit power source is constituted while having a capacitor 151 arranged near the servo drive device so as to prevent the instantaneous voltage drop of main circuit power source (the output of converter 102) as a storage means parallelly connected to the output of converter 102 and a voltage monitor circuit 152 arranged near the servo drive device so as to prevent the potential increase of main circuit power source (the output of converter 102) caused by power consumption when the output of converter 102 exceeds a prescribed potential. |
