<P>PROBLEM TO BE SOLVED: To solve the problem that, when a plurality of shaft control parts intend to use information of a single full-closed position sensor, a gain reduction in a position control loop occurs caused by delay in relaying of a signal between the shaft control parts, or the semi-closed position feedback gain for every motor is lowered under the influence of the upper limit of a full-closed loop gain since the full-closed loop gain at a position to be set is different due to the difference in a mechanical transfer mechanism between a drive motor and the sensor. <P>SOLUTION: In the motor controller, a speed command based on the full-closed position feedback is transferred from the first shaft control part to the other shaft control part, and the other shaft control part adjusts to use the speed command based on the semi-closed position feedback obtained from each shaft motor position and a speed command obtained from the first shaft control part. <P>COPYRIGHT: (C)2009,JPO&INPIT |
