DANGER
Caution: Danger for the operator!
Activating the handwheel does not automatically activate the
potentiometers of the handwheel; rather the potentiometers
on the operating panel of the control remain active. After an
NC start on the handwheel, the control immediately begins
with machining or with axis positioning, even though the
potentiometers on the handwheel are set to 0 %. There is a risk
of death to anybody inside the working space!
Before using the handwheel, set the potentiometers of the
operating panel to 0 %
When using the handwheel, always also activate the
potentiometers of the handwheel
The potentiometers of the machine operating panel continue to be
active after you have activated the handwheel. If you want to use
the potentiometers on the handwheel, proceed as follows:
Press the CTRL and handwheel keys on the HR 5xx at the
same time
The control shows the soft-key menu for selecting the
potentiometers in the handwheel's display.
Press the HW soft key to activate the handwheel
potentiometers
If you have activated the potentiometers on the handwheel, you
must reactivate the potentiometers of the machine operating panel
before deselecting the handwheel. Proceed as follows:
Press the CTRL and handwheel keys on the HR 5xx at the
same time
The control shows the soft-key menu for selecting the
potentiometers in the handwheel's display.
Press the KBD soft key to activate the potentiometers of the
machine operating panel
The control issues a warning if the handwheel potentiometers are
still active after the handwheel has been deactivated.
