<P>PROBLEM TO BE SOLVED: To provide a motor controlled position detection method which can detect acceleration accurately even if there is an error in serial communication of data and also can correct positional data accurately. <P>SOLUTION: This method has a step of reading in positional data periodically, a step of storing at least four or more pieces of read-in data in the past, a step of making the first acceleration data, using stored positional data P(i), P(i-1), and P(i-2), a step of comparing them with tolerable acceleration data, and a step of making a second acceleration data from the stored positional data P(i), P(i-2), and P(i-3) in case that the first acceleration data get over the tolerable acceleration data. Furthermore, this is equipped with a step of comparing the second acceleration data with the tolerable acceleration value, and a step of making positional data anew, using P(i-1) and P(i-2), in case that the second acceleration data get over the tolerable acceleration value. Hereby, a motor controller can detect the acceleration correctly and can correct the position accurately. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
