Normal
List Command set_fly_rot_pos
Function activates Processing-on-the-fly correction for compensation of workpiece or scan system
rotary movement (based on angular position values transferred to the RTC
®
5 via the
McBSP interface); thereby sets the corresponding
Resolution
parameter.
Restriction If the Processing-on-the-fly option is not enabled, then the command terminates the
Processing-on-the-fly process (even though it couldn’t have been activated).
Call
set_fly_rot_pos( Resolution )
Parameter
Resolution
number of steps per revolution (as a 64-bit IEEE floating point value);
allowed range: |
Resolution
| > 100.0
Comments • For Processing-on-the-fly correction and determining the
Resolution
parameter, see
"Processing-on-the-fly (Optional)", page 177 .
• Before executing the command set_fly_rot_pos , you should define the rotation center
for Processing-on-the-fly correction via set_rot_center or set_rot_center_list . Other-
wise, the default value (0|0) will be applied.
• If unallowed parameter values are supplied (e.g. for
Resolution
= 0), then
set_fly_rot_pos will not activate a Processing-on-the-fly correction or will deactivate a
Processing-on-the-fly correction previously activated via set_fly_rot_pos (but will not
deactivate any other Processing-on-the-fly correction). The latter case leads to a jump
(at jump speed) to the endpoint of the most recently executed vector or arc command
(without “
set_fly_rot_pos “ Processing-on-the-fly correction).
• The various Processing-on-the-fly corrections can’t be arbitrarily combined (see the
page 178 ).
• For deactivating Processing-on-the-fly correction, see page 186 .
• The McBSP interface can’t be simultaneously used for both Processing-on-the-fly appli-
cations and online positioning (see page 166 ).
• The McBSP interface always ignores the first FrameSync signal after a
load_program_file or mcbsp_init , so available data will not be transmitted (see
page 53 ).
