Traverse with electronic handwheels
DANGER
Caution: Danger for the operator!
Unsecured connections, defective cables, and improper use are
always sources of electrical dangers. The hazard starts when the
machine is powered up!
Devices should be connected or removed only by authorized
service technicians
Only switch on the machine via a connected handwheel or a
secured connection
The control supports traversing with the following new electronic
handwheels:
HR 510: Simple handwheel without display, data transfer via
cable
HR 520: Handwheel with display, data transfer via cable
HR 550FS: Handwheel with display, data transfer via radio
In addition to this, the control continues to support the cable
handwheels HR 410 (without display) and HR 420 (with display).
Refer to your machine manual.
Your machine tool builder can make additional functions
of the HR 5xx handwheels available.
If you want to use the
Handwheel superimp.:
function
in a virtual tool axis
VT
, then we recommend the
handwheel HR 5xx.
Further information: "Virtual tool axis VT", page 494
The portable HR 520 and HR 550FS handwheels feature a display
on which the control shows information. In addition, you can
use the handwheel soft keys for important setup functions, e.g.
presetting or entering and running M functions.
As soon as you have activated the handwheel with the handwheel
activation key, the operating panel is locked. The control shows this
status in a pop-up window on the 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.
