Pointer to the IODBHPST structure for the setting data for High-speed and high-precision machining. The IODBHPST structure is as follows.

typedef struct iodbhpst {
    short   slct;       /* flag of valid data */
    short   hpcc;       /* high precision contour control */
    short   multi;      /* multi buffer */
    short   ovr1;       /* override by Z-axis down */
    short   ign_f;      /* ignore feed at program */
    short   foward;     /* feed forward */
    long    max_f;      /* maximum feed of high precision */
                        /*                contour control */
    short   ovr2;       /* override at area 2 */
    short   ovr3;       /* override at area 3 */
    short   ovr4;       /* override at area 4 */
    long    reserve[7]; /* (not used) */
} IODBHPST ;

slct

Flag of valid data is set.

bit 0	:	high precision contour control
bit 1	:	multi buffer
bit 2	:	override by Z-axis down
bit 3	:	ignore feed at program
bit 4	:	feed forward
bit 5	:	maximum feed of high precision contour control
bit 6	:	override at area 2
bit 7	:	override at area 3
bit 8	:	override at area 4
bit 9,..,15	:	(not used)

* When a bit is 0, it means the CNC does not have the related option, then the corresponding data has no meaning.

ovr1

Valid/invalid of override by Z-axis down is set.

0	:	invalid
1	:	valid

ign_f

Valid/invalid of ignore feed at program is set.

0	:	invalid

foward

Valid/invalid of feed forward is set.
