Comments • The returned parameter values are also used by set_scanahead_params.
• Vmax is the maximum angular velocity of the galvanometers.
Vmax is not the mark speed in the image plane.
For this reason, the unit is “In bits/10 µs.” and not “In Bits/ms.”.
Distortion by the correction file is not yet taken into account in the returned parameter
value (see set_scanahead_params).
• HeadNo = 256 only returns meaningful values if set_scanahead_params was previously
called.
• The values returned by HeadNo = 256 are scaled. Do not use them with
set_scanahead_params( Mode = 2 ) because then they would be scaled again.
• For dual SCANahead systems (for example, 2 excelliSCAN scan heads; requires Option
“Second Scan Head Control”) it is recommended that the single SCANahead systems
used have as similar properties as possible (aperture, lens, correction file): For
automatic calculation of the Scanner Delays and Laser Delays, among other things, Amax
of SCANahead system HeadNo is required. The delays are only calculated for this
SCANahead system, but are also used unchanged for the second one. If the two
SCANahead systems differ too much for example, in Amax , unwanted deviations may
occur between the markings.
