CNC_ABSOLUTE2 | POSITION

Description

Differences between functions of cnc_absolute2 and functions of cnc_absolute are described.

The interface of function is similar to cnc_absolute function.

The cnc_absolute function reads an absolute actual position where the amount of all the tool offset was added to the command value. Therefore, the coodinates values called by cnc_absolute and absolute position displayed on the position display on CNC screen might be different by the setting of CNC parameter.

The cnc_absolute2 function reads the same value as the absolute position diaplayed on the position display on CNC screen.

• Series 15/15i, 30i, 0i-D/F, PMi-A

Both cnc_absolute and cnc_absolute2 read the same value as the absolute position displayed on the position display of CNC screen.

Declaration

Arguments

Specify the length of the data block(size of ODBAXIS structure)

ODBAXIS

for each axis	for all axes

• Series 15/15i, 30i, 0i-D/F, PMi-A

 

n = Maximum controlled axes
(The data for current controlled axes are valid.)

• Series 16/18/21, 16i/18i/21i, 0i-A/B/C, Power Mate i

 

n = Current controlled axes

typedef struct odbaxis {
    short   dummy ;                 /* Not used. */
    short   type ;                  /* Axis number. */
    long    data[MAX_AXIS] ;        /* Absolute position data of controlled axis. */
} ODBAXIS ;                         /* MAX_AXIS is the maximum controlled axes. */

Return

EW_OK is returned on successful completion, otherwise any value except EW_OK is returned.

The major error codes are as follows.

As for the other return codes or the details, see "Return status of Data window function"

CNC option

For HSSB connection,

The extended driver/library function is necessary.

For Ethernet connection,

The Ethernet function and the extended driver/library function are necessary.

However, in case of Series 16i/18i/21i-B, 0i-B/C/D/F, Series 30i and PMi-A, the required CNC option is as follows.

When Embedded Ethernet is used,

above two optional functions are not required.

When Ethernet board is used,

only Ethernet function is required.
