10. Important note for working in practice

Press any key of the PC keyboard to stop the carriage movement and to switch off

the milling machine. The system will then wait for further commands.

This "Keyboard Stop" is helpful during the test phase and for disruptions of machining

(e.g. wrong infeed, wrong feed).

Press the "Lock" (Sperren) switch of the CNC control to stop the carriage movement

and to switch off the spindle. The system will not accept any further commands until

the switch/pushbutton is returned to the "ON" (Ein) setting.

Your CNC machine no longer has a separate mains switch as it is

controlled directly via control electronics. However, during normal

work, make sure that the direction of rotation switch of the

machine (shown in the figure on the right) is not in the "0" setting,

but is set to the desired direction of rotation. Otherwise the

machine will not start.

That is why it must not be set to "0" during a machining procedure

either, since the spindle movement would be interrupted.

Room EMERGENCY Off: An EMERGENCY Off switch that disconnects the power

supply in the entire room must be installed in the room where the machines are

operated. This red/yellow coloured mushroom-shaped pushbutton must be easily

accessible and arranged far enough away from the possible hazardous area.
