Normal timed_jump_rel
List Command
Function moves the output point (of the laser focus) for the specified jump duration along a 2D
vector from the current position to the specified position (relative coordinate values)
within a two-dimensional image field.
Call
timed_jump_rel( dX, dY, T )
Parameters
dX, dY
T
Comments • The coordinates for the jump vector's end point are to be supplied as relative coordi-
nates with respect to the current position. Otherwise, the command is identical to
timed_jump_abs
® ®
RTC 4 RTC 5 unchanged functionality (except for the extended range of values, and T < 5 does not
execute timed_jump_rel, but instead jump_rel).
®
In RTC 4 compatibility mode, the RTC
(the permissible range of values is correspondingly reduced).

relative coordinates of the jump vector end point in bits as signed 32-bit
values; allowed range: [–8388608 ... 8388607] (out-of-range values will be
edge-clipped). The complete value range [–8388608 ... 8388607] is only
usable as a virtual image field e.g. for (enabled) Processing-on-the-fly
applications. The current coordinates will be clipped to [–524288 ... 524287]
(real image field size) during runtime directly prior to use of the correction
table.
duration of the complete jump vector in microseconds (as a 64-bit IEEE
floating point value); allowed range: [0 ... 167772160]; the parameter will be
rounded to an integer-multiple of 10; out-of-range values will be clipped.
If T < 5, then timed_jump_rel behaves like jump_rel.
(see the comments there, exception: T < 5, see above).
