Short
List Command
set_laser_delays
Function
sets the LaserOn delay and the LaserOff delay.
Call
set_laser_delays( LaserOnDelay, LaserOffDelay )
Parameters
LaserOnDelay
LaserOn Delay as a signed 32-bit value
1 bit equals 0.5
µ
s.
Allowed range: [ – 2
31
… +(2
21
–1)]
LaserOffDelay
LaserOff Delay as an unsigned 32-bit value.
1 bit equals 0.5
µ
s.
Allowed range: [0 … +(2
21
–1)]
Comments
• Values over (2
21
–1) will be clipped.
• The delays can be freely chosen within the permissible range. If
LaserOffDelay
<
LaserOnDelay
, overlaps of LaserOn and LaserOff will be automatically prevented during
processing of short vectors (see
"Automatic Delay Adjustments" on page 107
). The
LaserOffDelay
>
LaserOnDelay
condition required by the RTC
®
5’s predecessor boards
is therefore unnecessary.
• See the section
, for details.
• If the LaserOn Delay is negative, the total marking time is extended.
• The optional XY2-100 converter (see
) introduces a 10
µ
s runtime latency to
scan-system control. This runtime latency can be compensated by increasing the
LaserOn Delay and LaserOff Delay by 10
µ
s each.

4
RTC
®
5 essentially identical functionality (except for the extended range of values), however:
LaserOnDelay
and
LaserOffDelay
must be specified in units of 0.5
µ
s with the RTC
®
5; in
RTC
®
4 compatibility mode they are specified in units of 1
µ
s (as with the RTC
®
4). In RTC
®
4
compatibility mode, the RTC
®
5 multiplies the specified delays by 2 (the permissible range
of values is correspondingly reduced).
