innovators for industry
Variable
List Command
set_defocus_list
Function Like set_defocus, but a list command.
Restriction Like set_defocus.
Call set_defocus_list( Shift )
Parameters Shift Like set_defocus.
Comments • See set_defocus.
• Even though set_defocus_list is a short list command, execution of the directly
following list command is delayed by a few clock cycles due to the intermediate jump
to the changed z output. The extent of this delay depends on the size of the specified
focus shift; but it is at least 10 µs, even if Shift = 0.
• After the jump to the changed z output, a Jump Delay previously configured with
set_scanner_delays is inserted. Depending on the dynamics of the z axis it may be
reasonable to increase the Jump Delay before calling set_defocus_list. In case of a
SCANahead system with automatic delay calculation, long_delay can alternatively be
used to compensate for the Tracking Error of the z axis.
