Omitting orientation When the orientation at the time of switching to the spindle positioning mode is not required (for example,
Program origin The position at which the orientation is completed is regarded as the program origin. The program origin - Command system The command system comes in two types: The first positions a semi-fixed angle; the second positions an
Semi-fixed angle positioning Specify a positioning angle with an M code. Six types of M codes M α to M( α +5) can be specified. The value of α is set in parameter No. 4962 in advance. The positioning angles corresponding to M α to M( α +5) are listed below, and β is set in parameter No. 4963 in advance.
