Switching The Hr 550Fs On/Off - HEIDENHAIN iTNC 530 HSCI Technical Manual

Switching the
HR 550FS on/off
July 2013
To switch the HR 550FS off, press the CTRL key and the medium soft key
simultaneously. To switch the handwheel on, it is sufficient to press one of the
two permissive buttons. Then the HR 550FS runs a power-up test and can be
used after having completed the test. During the power-up test, the
background illumination of the HR 550FS is active, but the display remains
blank. The permissive buttons are tested at the end of the power-up test.
None of the permissive buttons may be pressed at this time. In the event of
error, an error message appears on the display, informing you that a
permissive button is pressed. As a result, the power-up test cannot be
completed. The display is filled with characters as soon as the power-up test
has been completed successfully, and the "OFF-LINE" message appears on
the display. If an error is found during the power-up test, an error message
appears on the display and the service department must be informed.
The handwheel is configured in a menu that you open by pressing the SET UP
WIRELESS HANDWHEEL soft key. After you have pressed the MOD key, this
soft key is displayed in the second soft-key row in the Programming and
Editing mode of operation if machine parameter MP7640 has been set to the
value of 12. The following functions are available for configuration:
Assigning the handwheel to a specific handwheel holder

Setting the transmission channel

Analyzing the frequency spectrum for determining the optimum

transmission channel
Selecting the transmitter power

Statistical information on the transmission quality

For configuring the HR 550FS handwheel, refer to the chapter "Configuring the
HR 550FS Wireless Handwheel" in the User's Manual for the control.
The functions that can be defined for the soft keys on the HR 550FS are the
same as for the HR 520(FS).
After the wireless handwheel has been configured and switched on, it can be
activated via the handwheel activation key. Machine operation then switches
from the machine operating panel to the handwheel. The machine tool builder
must ensure through the PLC program that the machine can be operated by
only one operating unit at any one time. Machine operating panel and
handwheel must never be active at the same time. The display of the wireless
handwheel and the display on the screen inform the operator when the
wireless handwheel is active.
