A.3 Activating The Contour Handwheel Via The Nc Program - Siemens SINUMERIK 808D User Manual

N o tes on part programs in "MDA" mode
Observe the following notes when creating, executing or editing part programs in "MDA" mode:
● Programs ended with M2/M30/M17
When a part program which is ended with M2/M30/M17 runs to the end in "MDA" mode, the cursor automatically returns
to the beginning of the program and the entire program becomes editable.
● Programs not ended with M2/M30/M17
When a part program which is not ended with M2/M30/M17 runs to the end in "MDA" mode, a new empty line
automatically appears at the end of the program and the cursor stops at the beginning of the new line. In this case, only
this new block line is editable and then executable. All program blocks before the new line, however, are not editable
unless you press the following key:
Note that if you do not enter any programming instruction in the new line, pressing the above key deletes the new line
and the cursor automatically goes back to the beginning of the program.
● Programs stopped under other circumstances
In one of the following cases, the program execution stops and the program is not editable unless you press the above
key:
– When a program exception occurs
– When the program runs to M0/M1
– When you press the following key:
A.3 Activating the contour handwheel via the NC program
The contour handwheel function can help you with the first cutting test after you create a new NC program. When you have
activated this function, you can control the feedrate of path and synchronized axes via a handwheel in "AUTO" or "MDA"
mode. This section only introduces how to activate the contour handwheel via the NC program. For how to activate this
function via the PLC interfaces, see the SINUMERIK 808D/SINUMERIK 808D ADVANCED Function Manual.
Pre conditions
● You must not select fixed feedrate, dry-run feedrate, thread cutting, or tapping.
N o te
If you have not programmed the feedrate in the previous blocks, the control system prompts an alarm which indicates the
absence of feedrate.
● The axes have been referenced. For more information about how to reference the axes, see Chapter "Switching on and
referencing (Page 20)".
● The option of "Contour handwheel" is activated with a license key. For more information about how to activate an option,
see the SINUMERIK 808D/SINUMERIK 808D ADVANCED Commissioning Manual.
● You have assigned the handwheel to the first geometric axis and activated it. For more information, see Section
"Assigning the handwheel through the MCP (Page 24)".
