CNC_RDSPMETER | POSITION

Description

Reads the spindle load meter data and the spindle motor speed data from 1st spindle to the specified spindle number.

In case that "data_num" is bigger than the current spindle number, this function sets the actual read spindle number (the current spindle number) to "data_num" variable after execution. And in case that "data_num" is smaller than the current spindle number, this function reads data for the specified spindle number which is specified by "data_num".

Declaration

#include "fwlib32.h" or "fwlib64.h"

FWLIBAPI short WINAPI cnc_rdspmeter(unsigned short FlibHndl, short type, short *data_num, ODBSPLOAD *loadmeter);

Arguments

FlibHndl   [ in ]

Specify the library handle. See "Library handle" for details.

type   [ in ]

Specify the data type.

0 : spindle load meter data
1 : spindle motor speed data
-1 : all type
data_num   [ in / out ]

Specify the pointer to the number of data to be read. This function returns the number of data which was read actually.

loadmeter   [ out ]

Specify the pointer to the array of ODBSVLOAD structure to store the spindle load meter data and the spindle motor speed data. The number of array must be equal to "*data_num". The ODBSVLOAD structure is as follows.

typedef struct odbspload {
    LOADELM     spload;     /* spindle load meter data */
    LOADELM     spspeed;    /* spindle motor data */
} ODBSPLOAD ;
svload
The LOADELM structure for spindle load meter data
spspeed
The LOADELM structure for spindle motor speed data And the LOADELM structure is as follows.

The LOADELM structure is as follows.

typedef struct loadelm {
    long    data;       /* load meter data, motor speed */
    short   dec;        /* place of decimal point */
    short   unit;       /* unit */
    char    name;       /* spindle name */
    char    suff1;      /* subscript of spindle name 1 */
    char    suff2;      /* subscript of spindle name 2 */
    char    reserve;    /* */
} LOADELM;
data
Load meter data, motor speed data
dec
Place of decimal point
unit
Unit
0 : %
1 : rpm
name
Spindle name (ASCII)
ASCII code 'S' is stored.
suff1

Subscript of spindle name 1 (ASCII)

  • Series 16/18/21, 16i/18i/21i, 0i, 30i, Power Mate i
    • The spindle number ('1', '2', ...) is stored.

  • Series 15i
    • The value which is defined by parameter (No. 5845, 5846) is stored.

    suff2

    Subscript of spindle name 2 (ASCII)
    When the spindle switching function is available, the following ASCII code is stored.

    In case of main spindle : '1'
    In case of sub spindle : '2'

    When the spindle switching function is not available, NULL('\0') is stored.
    In case of Series 15, data is stored. But it is invalid for the spindle name.

    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
    EW_LENGTH
    (2)
    Data block length error
    The spindle number (data_num) is 0 or less.
    EW_ATTRIB
    (4)
    Data attribute error
    Type of data (type) is wrong.

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

    CNC option

    And this function is related to the following CNC option.

      This function is related to the spindle switching control.

    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 15i
    • 5845, 5846 (influenced by setting)

    CNC mode

    This function can be used in any CNC mode.

    Example(C Language)

     
    The following program reads all spindle load meter, and displays them.
    
    #include "fwlib32.h"
    
    void example( void )
    {
        ODBSPLOAD sp[4];   /* 4 = maximum spinlde number */
        short num = 4;
        short ret = cnc_rdspmeter(h, 0, &num, sp);
    
        if(!ret) {
            int i;
            for(i = 0 ; i < num ; i++) {
                printf("%c%c = %d\n", 
                sp[i].spload.name, sp[i].spload.suff1,

            byte[] bytes = new byte[Marshal.SizeOf(sp) * 4];
            IntPtr ptrWork = Marshal.AllocCoTaskMem(Marshal.SizeOf(sp));
    
            short ret = Focas1.cnc_rdspmeter(h, 0, ref num, bytes);
            if (ret == Focas1.EW_OK)
            {
                int i;
                for (i = 0; i < num; i++)
