14.34.3.3 Initial Parameter Settings: Setting Stations (#12801 to #12805, #12850 to
#12868)
Set the positioning destinations (stations).
When assigning stations with evenly-spaced intervals: Uniform assignment
When assigning stations to arbitrary coordinates: Arbitrary coordinate assignment
Uniform assignment setting
Uniform assignment will be selected by turning OFF "#12803 aux_Cont2/bit4".
The assignment divides one rotation (360°) of rotary axis, and evenly divides the designated range of linear axis. The divided
points will be stations.
Station Nos. will be assigned automatically in ascending order. The one closer to the reference position (zero point) gets
smaller No.
 For rotation axis
Set the number of division points of one rotation (360°) (number of stations) to the parameter "#12801 aux_station1(Number
of indexing stations)". The number of stations must be an integral number from 2 to 360. Station 1 will be assigned on the
reference position. Station 2 onwards will be assigned in order in the motor CW (forward) direction.

 For linear axis
Decide the interval of stations based on the linear axis stroke length and the number of stations to evenly assign the stations.
Station 1 will be assigned on the shifted position by amount of "#12805 aux_ST.offset (Station offset)" from the coordinate
zero point (coordinate position = 0). Station 2 onwards will be positioned in order in the assignment direction ("#1018 ccw").
Thus, the last station will be assigned on the coordinate which is linear axis stroke length (set in "#12804 aux_tleng") away
from station 1.
