10 RTC6 Commands

Normal List
Command
arc_abs
Function Moves the laser focus from the current position at mark speed along an arc with the
specified angle and center point (absolute coordinate values) within a 2D Image Field.
Call
arc_abs( X, Y, Angle )
Parameters
X
Absolute x coordinate of the arc center. In bits.
As a signed 32-bit value.
Allowed value range: [–268,435,456…+268,435,455].
Out-of-range values are clipped to the boundary values.
Y
Like
X
(analogously).
Angle
Arc angle. In degrees.
As a 64-bit IEEE floating point value.
A positive sign means “clockwise”.
Allowed value range: [–3,600.0°…+3,600.0°] (±10 full circles).
Out-of-range values are clipped to the boundary values.
Comments • If the mark speed has not been previously explicitly set by set_mark_speed or
set_mark_speed_ctrl, then the marking is executed at a predefined mark speed of
1,000 bits/ms.
• The Signals for “Laser Active” Operation are automatically turned on at the beginning
of the marking (or remain on after a directly preceding [*]mark[*] Command or
“Arc” Command). The defined Scanner Delays and Laser Delays are thereby taken into
account, see Chapter 7.2 ”Delay Settings – Coordinating Scan Head Control and Laser
Control”, page 145. Note that other delays are executed in Sky Writing mode.
Exception: zero-length “Arc” Commands, see Section ”Notes”, page 149.
RTC4RTC6 Unchanged functionality. In addition: increased value range.
In RTC4 Compatibility Mode, the RTC6 multiplies the specified values for
X
and
Y
by 16.
The allowed value ranges decrease accordingly.
RTC5RTC6 Unchanged functionality. In addition: increased value range.
Version info Available as of DLL 600, OUT 600, RBF 600.
