<P>PROBLEM TO BE SOLVED: To provide a servo motor control system capable of little generation of over-voltage trip due to regenerative protection voltage and high regenerative energy efficiency. <P>SOLUTION: To DC power supply 1, motor drives 10, 20 are connected in parallel. The motor drives 10, 20 includes charging means 13, 23 for charging electric power through diodes 12, 22 and DC link terminals 11a, 21a for directly outputting voltages of the charging means 13, 23 to control servo motors 15, 25. The plurality of DC link terminals 11a, 21a are connected in parallel. <P>COPYRIGHT: (C)2008,JPO&INPIT |
