timed_para_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 and, simultaneously as well as linearly, changes the
signal parameter selected via set_vector_control to the specified value.
Call
timed_para_jump_abs( X, Y, P, 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.
P
End value of the signal parameter as an unsigned 32-bit value; allowed range:
dependent on the selection made via set_vector_control (
Ctrl
parameter),
identical with set_vector_control (
Value
parameter)
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_para_jump_abs behaves like para_jump_abs.
Comments • Unlike para_jump_abs, the timed_para_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.
• timed_para_jump_abs requires two list entries. During runtime, the command’s part
on the first list entry is executed as a short list command and afterward the second part
is executed as a normal list command. Thereby, both command parts are executed
within the same 10 µs clock, unless further (previous) short list commands induce a
list_nop between the two parts.
•If
T
< 5, then timed_para_jump_abs behaves like para_jump_abs. Then it requires
only one list entry.
• 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).

In RTC
®
4 compatibility mode, the RTC

5 multiplies the specified coordinate values by 16
(the permissible range of values is correspondingly reduced).
