5.3 Program Testing
Brief
: The automatic operation detection should be firstly performed before machining, which is
tested whether the generated program is correct. When the machine does not operate, the
detection is performed by the change viewing the position display or the actual operation
machine tool.
5.3.1 Machine Tool Lock
Brief
Do not move the change of the machine tool monitoring position display.
When all axes of the machine tool lock signal MMLK is set to 1, stop to output pulse to the servo
motor during manual or Auto operation, but the code distribution is still performed, and the absolute
and relative coordinates are also renovated. So, the operator can check whether the code
compilation is correct viewing the change of the monitor position.
