Description
Differences between functions of cnc_relative2 and functions of cnc_relative are described.
The interface of function is similar to cnc_relative function.
The cnc_relative function reads an relative actual position where the amount of all the tool offset was added to the command value. Therefore, the coodinates values called by cnc_relative and relative position displayed on the position display on CNC screen might be different by the setting of CNC parameter.
The cnc_relative2 function reads the same value as the relative position diaplayed on the position display on CNC screen.
(Note) | Only when CNC control software supports the cnc_relative2 function at the special series and version, cnc_relative2 reads the same value as the relative position diaplayed on the position display on CNC screen. If CNC control software does not support this function, cnc_relative2 reads the same value returned by cnc_relative. |

- Series 15/15i, 30i, 0i-D/F, PMi-A
Both cnc_relative and cnc_relative2 read the same value as the relative position displayed on the position display of CNC screen.

Declaration
Arguments
Specify the library handle. See "Library handle" for details.
Specify axis number to read.
ALL_AXES | : | for all axes(ALL_AXES : -1) |
1,..,m | : | for each axis(m : number of controlled axis) |
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
Pointer to the ODBAXIS structure including the relative position data of the controlled axes. The ODBAXIS structure is as follows.
typedef struct odbaxis {
short dummy ; /* Not used. */
short type ; /* Axis number. */
long data[MAX_AXIS] ; /* Relative 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.
Return code | Meaning/Error handling |
---|---|
(2) |
Size of ODBAXIS structure(length) is illegal. |
(4) |
The specification of axis number (axis) is improper. |
As for the other return codes or the details, see "Return status of Data window function"
CNC option
For HSSB connection,
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.
