Traverse with electronic handwheels

The TNC supports traversing with the following new electronic

HR 520: Handwheel with display, data transfer per cable

HR 550FS: Handwheel with display, data transfer via radio

In addition to this, the TNC continues to support the cable

handwheels HR 410 (without display) and HR 420 (with display).

Caution: Danger to the operator and handwheel!

All of the handwheel connectors may only be

removed by authorized service personnel, even if it is

possible without any tools!

Ensure that the handwheel is plugged in before you

switch on the machine!

If you wish to operate your machine without the

handwheel, disconnect the cable from the machine

and secure the open socket with a cap!

Refer to your machine manual. Your machine tool

builder can make additional functions of the HR 5xx

If you want to use the handwheel superimposing

function on a virtual axis, then we recommend the

handwheel HR 5xx.

Further Information:

The portable HR 5xx handwheels feature a display on which the

TNC shows information. 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.
