Delayed Short
List Command
set_mark_speed
Function
defines the marking speed for the subsequent vector and arc commands
Call
set_mark_speed( Speed )
Parameter
Speed
marking speed in
bits per ms
(as a 64-bit IEEE floating point value)
Allowed range: [1.6 … 800000.0]
Comments
• By default a marking speed of 1000
bits per ms
is preset.
• The specified marking speed (or the preset marking speed, if no other value has been
specified) is used for all subsequent mark and arc commands until a new value is spec-
ified.
• To obtain the actual marking speed
v
in the image plane (in
meters per second
), the
specified speed value (in
bits per ms
) must be divided by the calibration factor
K
of the
correction table (in
bits per mm
):
v
mark
=
Speed
/
K
The calibration factor
K
can be queried from the correction table via
• The
set_mark_speed
command is also available as the control command

5 unchanged functionality (except for the extended range of values)
The image field coordinates for the X and Y axes (but not the Z axis) and all related
parameters (e.g. marking speed or wobbel amplitude) are specified as 20-bit values; in
RTC
®
4 compatibility mode they are specified as 16-bit values (as with the RTC
®
4) and the
RTC
®
5 multiplies the specified value for
Speed
by 16 (the permissible range of values is
correspondingly reduced to [0.1 … 50000.0]).

Ctrl Command set_mark_speed_ctrl
Function
same as
(see above), but a control command
Call
set_mark_speed_ctrl( Speed )
Parameter
Speed
marking speed in
bits per ms
(as a 64-bit IEEE floating point value)
Allowed range: [1.6 … 800000.0]
Comments
• The command will be ignored (
:
RTC5_BUSY
) if the board’s
BUSY status is currently set (list is being processed or has been halted via
In contrast, the command is executed when a list has been paused via
(
PAUSED status set) or the board’s INTERNAL-BUSY status is currently set.
