Speed specification
With the setting wheel X (Fig. 2) you can adjust the speed continuously. The concrete speed values of
individual stages can be found in the table on page 5 or on the speed sticker on the housing.
Until the motor characteristic is reached, the built-in electronics readjust to the set speed.
5.3.1
Speed setting in PV design
In “portal mode”, the position of the setting wheel X (Fig. 2) for the speed setting is ignored. The speed can
only be changed by the voltage at the pin “U
S
“. If you wish to set the speed by means of the setting wheel X
(Fig. 2), “portal mode” must first be deactivated by switching off the power supply at the pin “U
PV
“ or by
removing the PV control cable.
The correlation between speed and control voltage is illustrated in formulae (1) and (2).
5.4
Overload protection
Danger
If you carry out any work on the working spindle after the overload protection has
triggered, the mains plug must first be removed.
To protect the power tool, the operating parameters current, speed and temperature are dynamically monitored
and the power tool is switched off if necessary. Shortly before the overload protection is tripped, the
illumination of the setting wheel X (Fig. 2) changes to a permanent red (RD).
To put the power tool back into operation, you must open and close power switch 5 (Fig. 1). The power tool
goes into operation and the illumination of the setting wheel X (Fig. 2) changes to blue (BU).
5.4.1
Optical display of the remaining runtime
Triggering of the overload protection during operation leads to breakage of the milling tool, damage to the
workpiece or even damage to the portal system. You can prevent this by paying attention to the visual output
signals at the setting wheel X (Fig. 2).
As long as the power tool is not overloaded in terms of performance, the setting wheel lights up permanently in
blue (BU).
If the power tool is overloaded, the calculated remaining runtime is displayed flashing in red (RD). On page 6
(Fig. 7) you can see the temporal arrangement of the pulses in overload mode. The correlation between the
flashing behaviour and the associated remaining runtime is shown in the bottom table 4 on page 29.
