<P>PROBLEM TO BE SOLVED: To prevent the time required for a carriage to reach the target stop position from getting longer. <P>SOLUTION: In case that the travel speed Vn of a carriage computed by a velocity converter is larger than the assumed velocity Va in the deceleration zone of the carriage (s420:YES), this motor controller can perform the braking by the braking method (s450, s460) geared to the controlled output Uo generated by a motor control unit. By performing such braking, the travel speed of the carriage gets to drop to the assumed velocity Va by braking. At this time, the braking to the carriage is performed, according to the deviation between the target velocity Vt and the travel velocity Vn and the deviation between the present position Xn and the target stop position Xt, so even if the braking force required to perform the braking to the carriage varies with individual difference of a carriage controller or conditions such as the operation state of the carriage, etc., it can brake the carriage by the braking force geared to the conditions. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
