METHOD FOR CONFIRMING CONFORMANCE BETWEEN CONSTANTS IN MASTER AND SLAVE IN DRIVE DEVICE

PROBLEM TO BE SOLVED: To provide a method which very rapidly and easily confirms whether the constant of a master conforms to that of a slave when there are a plurality of constants to conform to each other between the master and the slave in a double winding drive. SOLUTION: Necessity of conformity confirmation is determined (ST1), and a plurality of the constants to be conformed to each other between the master 3 and slave 4 are stored in the master 3 and in the slave 4, respectively (ST2). The constants are computed in the master 3 and in the slave 4 by using cyclic redundancy check computation (ST3), and the constant computation result of the slave 4 is transmitted to the master 3 by communication (ST4). The master 3 determines the conformity or nonconformity between the constants (ST6) by comparing the constant computation result of the master 3 with that of the slave 4 instead of constant-set values themselves (ST5). When the nonconformity exists, the master 3 outputs a warning to operation/display parts 6a-6b (ST7). COPYRIGHT: (C)2005,JPO&NCIPI
