CNC_WRVOLC | NCDATA

Specify the library handle. See "Library handle" for details.

Pointer to the ODBTOFS structure including the writing information of 3-dimensional error compensation data. The ODBVOLC structure is as follows.

typedef struct odbvolc {
    long   start_no ;  /* Writing start compensation number */
    long   start_ax ;  /* Writing start axis index */
    long   end_no ;    /* Writing end compensation number */
    long   end_ax ;    /* Writing end axis index */
    long   num ;       /* Writing number */
    char   type ;      /* 0:Write by number  1:Write by end number specification */
    long   data[72] ;  /* Reserved */
} ODBVOLC ;

start_no

Specify the compensation number which the writing start.
The range is 1-15625.

start_ax

Specify the axis index number which the writing start.
The range is 1-3.

end_no

Specify the compensation number which the writing end. This argument is effective at type=1.
The range is 1-15625.

end_ax

Specify the axis index number which the writing end. This argument is effective at type=1.
The range is 1-3.

num

Specify the writing number. This argument is effective at type=0.
The range is 1-78.

type

Specify the writing method type.

0	:	Write by number(Specify the "num")
1	:	Write by end number specification(Specify the "end_no","end_ax")

When type=1 is specified for the writing method type, specify the other argument to become the following.

1 <= ((end_no - start_no) * 3 + (end_ax - start_ax) + 1) <= 78

Pointer to the area including the 3-dimensional error compensation data. The number of maximum data which can write is 78.

(Maximum size is data[78].) The range of compensation data is -128 to 127.

Data is stored in order of the 1st axis, 2nd axis and the 3rd axis from the little number.

For example, when the data from the 2nd axis in No.3 to the 1st axis in No.8 is updated by the end number specification, the set data becomes as follows.

ODBVOLC volc ;

long data[78] ;

volc.start_no = 3

volc.start_ax = 2

volc.end_no = 10

volc.end_ax = 1

volc.type = 1(end number specification)
