Arc_Rel - Scanlab RTC 5 PC Interface Board Installation And Operation Manual

Normal

arc_rel

List Command
Function moves the laser focus from the current position at marking speed along an arc with the
specified angle and center point (relative coordinate values) within a two-dimensional
image field.
Call
arc_rel( dX, dY, Angle )
Parameters
dX,dY
Angle
Comments • The coordinates for the arc center are to be supplied as relative coordinates with respect
to the current position. Otherwise, the command is identical to
comments there).
• The current coordinates will be clipped to [–524288 ... 524287] (real image field size)
during runtime directly prior to use of the correction table.

RTC 4 RTC 5 unchanged functionality (except for the extended range of values).
®
In RTC 4 compatibility mode, the RTC
values by 16 (the permissible range of values is correspondingly reduced to
[–524288 ... 524287]).
