Note
When the control is switched on, the axes can be traversed right up to the limits of the
machine as the reference points have not yet been approached and the axes referenced.
Emergency limit switches might be triggered as a result.
The software limit switches and the working area limitation are not yet operative!
The feed enable signal must be set.
