Traverse with electronic handwheels
The TNC supports traversing with the following new electronic
handwheels:
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
available.
If you want to use the handwheel superimposing
function on a virtual axis, then we recommend the
handwheel HR 5xx.
Further Information: "Virtual tool axis VT", page 400
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.
If several handwheels are connected to a control the handwheel
key is not available on the operating panel. Activate or deactivate
the handwheel via the handwheel key on the handwheel. An active
handwheel must be deactivated before another handwheel can be
selected.
Refer to your machine manual.
This feature must be enabled and adapted by the
machine tool builder.
