<P>PROBLEM TO BE SOLVED: To provide a servo driver attaining cost reduction even in single-axis control or in multiaxis control and restoring regenerative voltage to an alternating-current power supply in multiaxis control. <P>SOLUTION: Provided is a power supply module having: a servo driver module 1 that does not include a regenerative circuit and has only a rectifying section 19 for alternating-current power supply; a regeneration module 2 having a regenerative circuit 18 connected to a direct-current voltage terminal of the servo driver module 1; and a power supply module having the rectifying section 19 for alternating-current power supply and the regenerative circuit 18. When the servo driver is subjected to single-axis control, the servo driver module 1 and the regenerating module 2 are connected. When it is subjected to multiaxis control, the direct-current voltage terminals of the multiple servo driver modules 1 are connected together, and the power supply module 3 is connected to one end of them. Thus, the servo drive module 1 can be used both in single-axis control and in multiaxis control. <P>COPYRIGHT: (C)2007,JPO&INPIT |
