Title: Motor controller and recorder
Inventor: KIMIE KAZUYA
IPC: H02P29/00
Filed: 2002-06-11
Abstract: <P>PROBLEM TO BE SOLVED: To obtain a motor controlling means which can exactly stop a driven object at a target halting position without being influenced by a load fluctuation and without changing the halting position.  <P>SOLUTION: The target velocity V of the motor is determined by referring to a target velocity table in which the target velocity V of the motor is set in response to the shifting position of the driven object. Usually, the motor controller reads out the target velocity V from address n=5 as a reference initiating position to address n=n+5 as a reference terminating position. If the load of the driven object fluctuates the readout range (reference range) is shifted to the upper limit, thereby changing the target velocity V so that the driven object is stopped exactly at the target halting position.  <P>COPYRIGHT: (C)2004,JPO
