5.3 Speed selection

The setting wheel 3 permits a stepless change of the rotational speed. The concrete values of the rotational
speed of the individual steps can be found in the table below or on the rotational speed sticker on the housing.
The integrated electronics corrects to the selected rotational speed until the motor characteristic curve is
reached.

5.4 Overload protection

Overload during operation causes the milling tool to break, the workpiece to be damaged or even the milling
motor or gantry system to be damaged.
To protect the milling motor, the operating
parameters current, rotational speed and
temperature are monitored dynamically, and the
milling motor is switched off if necessary.
A short moment before the overload protection is
activated, the light at the setting wheel 3 changes to
permanent red.
To be able to restart the milling motor, switch the
circuit breaker (2) off and back on. The milling
motor becomes operational and the light at the
setting wheel (3) changes to blue.
Prior to carrying out any work on the work spindle after the overload protection has been
activated, ensure that the mains plug is pulled out.
