Undelayed set_laser_delays
Short
List Command
Function sets the LaserOn delay and the LaserOff delay.
Call
set_laser_delays( LaserOnDelay, LaserOffDelay )
Parameters
LaserOnDelay
LaserOffDelay
Comments • Values over (2
• 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
LaserOffDelay > LaserOnDelay condition required by the RTC
is therefore unnecessary.
• See the section
• If the LaserOn Delay is negative, the total marking time is extended.
• The optional XY2-100 converter (see
scan-system control. This runtime latency can be compensated by increasing the
LaserOn Delay and LaserOff Delay by 10 µs each.

RTC 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 µs with the RTC

RTC 4 compatibility mode they are specified in units of 1 µs (as with the RTC
compatibility mode, the RTC
of values is correspondingly reduced).
