Pointer to the IODBHPPR structure for the tuning data(parameter input) for high-speed and high-precision machining. The IODBHPPR structure is as follows.

slct

Flag of valid data is set.

bit 0	:	fine level
bit 1	:	acceleration/deceleration level
bit 2	:	maximum feed
bit 3	:	time constant for before IPL
bit 4	:	time constant for after IPL
bit 5	:	difference of corner feed
bit 6	:	clamp by acceleration
bit 7	:	radius of feed clamp by radius of circle
bit 8	:	maximum feed of feed clamp by radius of circle
bit 9	:	minimum feed of feed clamp by radius of circle
bit10	:	coefficient of feed forward
bit11,..,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.

diff

Each bit indicates whether the corresponding data is common for all axes, or not.

bit 0,..,3	:	(not used)
bit 4	:	time constant for after IPL
bit 5	:	difference of corner feed
bit 6	:	clamp by acceleration
bit 7,..,9	:	(not used)
bit10	:	coefficient of feed forward
bit11,..,15	:	(not used)

* When the bit value is 0, it means the corresponding data is applied commonly to all axes.
