Normal set_fly_x_pos
List Command
Function activates Processing-on-the-fly correction for compensation of a linear workpiece or scan
system movement in the X direction (based on position values transferred to the RTC
the McBSP interface); thereby sets the corresponding scaling factor.
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_x_pos( ScaleX )
Parameter
ScaleX
Comments • For Processing-on-the-fly correction and determination of the scaling factor, see
"Processing-on-the-fly (Optional)", page
• If unallowed parameter values are supplied (e.g. for ScaleX = 0), then set_fly_x_pos
will not activate a Processing-on-the-fly correction or will deactivate a Processing-on-
the-fly correction previously activated via set_fly_x_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_x_pos" Processing-on-the-fly correction).
• The various Processing-on-the-fly corrections can't be arbitrarily combined (see the
page
• For deactivating Processing-on-the-fly correction, see
• For one-dimensional correction (when only set_fly_x_pos is used), the McBSP interface
provides a (signed) 32-bit value. In contrast, only a (signed) 16-bit value per axis is
supplied for two-dimensional correction (set_fly_x_pos and set_fly_x_pos). Here,
set_fly_x_pos uses the McBSP interface's lower 16 bits for the X value and
set_fly_x_pos
• The McBSP interface can't be simultaneously used for both Processing-on-the-fly appli-
cations and online positioning (see
• The McBSP interface always ignores the first FrameSync signal after a
