CNC_RDDYNAMIC | POSITION

Description

Read various data which changes at CNC operation at a time. The data which can be read is as follows.

Data Function used for reading individually
Alarm status cnc_alarm
Program number in executing cnc_rdprgnum
Program number of the main program cnc_rdprgnum
Sequence number cnc_rdseqnum
Actual feed rate cnc_actf
Actual spindle speed cnc_acts
Absolute position data of controlled axis (2) cnc_absolute2
Machine position data of controlled axis cnc_machine
Relative position data of controlled axis (2) cnc_relative2
Amount of distance to go of controlled axis cnc_distance

The formats of each data are same as "Function used for reading individually". Refer to each function for details.

The data concerning the axis is read by specified with axis. Each data is stored in oaxis structure in ODBDY.

All axes can be read at a time by specifying ALL_AXES for "axis". In that case, various data concerning the axis is stored in each array of faxis inside of ODBDY.

The decimal point position of the various data concerning the axis can be acquired in the cnc_getfigure function.

  • Series 15i
    • This function cannot read all alarm status.
      Please use cnc_rddynamic2 function in order to read all alarm status.
      it is necessary to switch API to the one for the program number 8 digits. See "Program number 8 digits" for details.

  • Series 16/18/16i/18i, Power Mate i
    • it is possible to use this function for the program number 8 digits, however it is necessary to switch API to the one for the program number 8 digits. See "Program number 8 digits" for details.

  • Series 16i/18i-W
    • the data corresponding to "Actual spindle speed", "Amount of distance to go of controlled axis" cannot be got.
