HR 420 electronic handwheel
Unlike the HR 410, the HR 420 portable handwheel is equipped with
a display. In addition, you can use the handwheel soft keys for
important setup functions, e.g. datum setting or entering and running
M functions.
As soon as you have activated the handwheel with the handwheel
activation key, the operating panel is locked. This is indicated by a pop-
up window on the TNC screen.
The HR 420 handwheel features the following operating elements:
It is also possible to move the machine axes with the handwheel
during program run if M118 is active.
