3.2 Display and operator control options in the main screen
When the spindle is switched off, it brakes and comes to a halt. If a spindle brake is fitted, it
is applied. If there is no spindle brake or it is switched off, the spindle can be rotated freely
once it has stopped.
The programmed spindle speed can be controlled by means of an appropriate spindle
override switch setting (e.g., 50 %).

Tool change

Functionality
A basic differentiation must be made between a manual and an automatic tool-changer
system.
For an automatic system, the tool change is controlled by the PLC user program. The
currently loaded tool is displayed in the "Manual Machine Plus" main screen.
For a manual system, the required tool number is manually entered from an input screen
form.
