Command
timed_arc_abs
Function Moves the laser focus for the specified marking duration from the current position along
an arc with the specified angle and center point (absolute coordinate values) within a
2D Image Field.
Call timed_arc_abs( X, Y, Angle, T )
Parameters X Like arc_abs.
Y Like arc_abs.
Angle Like arc_abs.
T Duration of the complete arc marking process. In µs.
As a 64-bit IEEE floating point value.
Allowed value range: [0…167,772,160]. The parameter is rounded to an
integer-multiple of 10. Out-of-range values are clipped.
If T < 5, then timed_arc_abs behaves like arc_abs.
Comments • Unlike arc_abs, timed_arc_abs does not execute the marking process with the
specified (by set_mark_speed or set_mark_speed_ctrl) mark speed. Instead, the
speed (that is, the number of Microsteps) is adjusted so that the arc lasts as long as
specified (see Chapter 8.9 ”Timed Commands”, page 274). The total marking time is
(for T  5) the sum of the specified (rounded) time and the set delays.
