HR 420 Electronic Handwheel

Unlike the HR 410, the HR 420 portable handwheel is equipped with
a display. In addition, you can run important setup functions through
the handwheel soft keys, e.g. setting datums or entering and running
M functions.

As soon as you press the handwheel activation key, it activates the
handwheel and deactivates the control panel. This is indicated by a
pop-up window on the TNC screen.

The HR 420 handwheel features the following operating elements:

If M118 is active, it is even possible to move the machine axes with the
handwheel during the program run.
