List Command
timed_jump_abs
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 (absolute coordinate values)
within a two-dimensional image field.
Call
timed_jump_abs( X, Y, T )
Parameters
X, Y
absolute 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.
T
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_abs behaves like jump_abs.
Comments • Unlike jump_abs, the timed_jump_abs command doesn’t execute the jump with the
specified (via set_jump_speed or set_jump_speed_ctrl) jump speed. Instead, the
speed (i.e. the number of microsteps) will be adjusted so that the vector lasts as long
as specified (see chapter 8.10 "Timed Vector and Arc Commands", page 198). The total
jump time is (for
T
5) the sum of the specified (rounded) time and the set delays.
• The “laser active” laser control signals are off during the jump (if necessary, they will be
switched off before the jump).
• After a jump command, a (variable) jump delay is inserted. Exception: a zero-length
jump vector’s subsequent (variable) jump delay will not be executed. However, the
command itself still requires a 10 µs clock cycle for execution.
• During the conversion of specified coordinate values into scan system output values,
any previously defined coordinate transformations, assigned correction tables etc. are
taken into account after successful microvectorization (see page 126).

RTC
®
5 unchanged functionality (except for the extended range of values, and
T
< 5 does not
execute timed_jump_abs, but instead jump_abs).
In RTC
®
4 compatibility mode, the RTC
®
5 multiplies the specified coordinate values by 16
(the permissible range of values is correspondingly reduced).
