Arbitrary coordinate assignment setting
Arbitrary coordinate assignment will be selected by turning ON "#12803 aux_Cont2/bit4".
The number of stations for arbitrary coordinate assignment is 20 at maximum.
Station 1 will be assigned on the coordinate zero point (coordinate position = 0). Stations 2 to 20 are set with the parameters
"#12850 aux_stpos2" to #12868 aux_stpos20".
Setting an offset amount in "#12805 aux_ST.offset (Station Offset)" shifts the stations 1 to 20 by the offset amount.
Note
(1) The set values (coordinate positions) of stations 2 to 20 does not need to be in ascending order.

Set this parameter in hexadecimal format. The bits that are not explained here must be
set to "0".

0: Uniform assignment
1: Arbitrary coordinate assignment
Set the number of stations. For linear axis, the number of divisions
is obtained by subtracting "1" from the number of stations.
Set the movement stroke length for linear axis.
This parameter is meaningless at the arbitrary coordinate assign-
ment or arbitrary coordinate command.
Set the distance (offset) between the reference position and station
1.
