CNC_ABSOLUTE | POSITION

Description

Reads the absolute position data of axis specified with "axis". The absolute position is stored in "data[0]" of "ODBAXIS".

All axes can be read at a time by specifying ALL_AXES for "axis". In that case, an absolute position of each axis is stored in the data array of ODBAXIS.

The decimal point position of the absolute position can be acquired in the cnc_getfigure function.

• Series 15/15i

The relation to the read absolute position, amount of Tool Length Compensation and Cutter Radius Compensation, and amount of servo delay and acceleration/deceleration delay follows setting the CNC parameter of the following description.

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

Amount of Tool Length Compensation and Cutter Radius Compensation, and amount of servo delay and acceleration/deceleration delay is always included in the read absolute position.

• Series 16i/18i-W

Amounts of Wire diameter Compensation, amounts of servo delay and acceleration/deceleration delay is always included in the read absolute position.

• Series 30i/31i/32i, 0i-D/F, Power Motion i-A

Amount of Tool Length Compensation and Cutter Radius Compensation is always included in the read absolute position. But, amount of servo delay and acceleration/deceleration delay is not included.

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.

CNC parameter

This function is related to the following CNC parameter.
See the manual of CNC parameter for details.

• Series 15
2204#1=1, 7613#0=1 (must be set)

M series:2202#2, #3, #4, #5 (influenced by setting)

T series:2202#4, #5, 2203#3 (influenced by setting)

• Series 15i
2202#2,#3,#4,#5 (influenced by setting)

• Series 30i, 0i-D/F, PMi-A
3104#6,#7 (influenced by setting)

CNC mode

This function can be used in any CNC mode.

Available CNC

Note) 0i-C does not support the HSSB function.

Example(C Language)

The following program displays 
    1:  120005
    2:  -50119
    3:      80
while the absolute position data for each axes are
    The 1st axis    120.005
    The 2nd axis    -50.119
    The 3rd axis      0.080
in 3-axis system.
(in case of "mm input" and "IS-B".)
