- 682 - - Latitude and longitude directions When bit 1 (FLL) of parameter No. 12320 is set to 1, the feed direction is defined as follows: T ) and normal axis direction vector ( P ) (parameter No. 12321) be the table horizontal direction 1 (longitude direction) vector ( 1 R ). When table horizontal direction 1 is selected, a movement in the positive direction means a movement in this vector direction, and a movement in the negative direction means a movement in the T P R × = 1
Let a vector perpendicular to the table vertical direction vector ( T ) and table horizontal direction 1 (longitude direction) vector ( 1 R ) be the table horizontal direction 2 (latitude direction) vector ( 2 R ). When table horizontal direction 2 is selected, a movement in the positive direction means a movement in 1 2 R T R × =
