3) Real-time external control function
The position command data can be retrieved and operated at
the robot motion control cycle unit. Joint, XYZ or motor pulse
can be designated for the position data. It is also possible to
monitor the input/output signals or output the signals
simultaneously.
Control is started with the MXT command (MELFA-BASIC
V/VI language).
* The user must create an
application program on the
personal computer side to
