Load_Position_Control - Scanlab RTC6 PCIe Board Installation And Operation Manual

Ctrl Command load_position_control
Function Loads a table with data points from an ASCII text file and determines – by linear
interpolation – the scaling function for position-dependent laser control
(radial correction, see
NoOfDataPoints = load_position_control( Name, No )
Call
Name
Parameters
No
Result A positive error code in case of an error. The negative number of found data points in case
of success. As a signed 32-bit value.

Comments • The format requirements for the text file's table entries with data points for
position-dependent laser control are described in
Function", page
for the entire range of control values.
• load_position_control overwrites any previously loaded scaling
function for position-dependent laser control.
• For Name =
Scale(Position)=1.0 is loaded for the complete position range so that no position-
dependent correction takes place.
• Position-dependent laser control only takes effect during subsequent

Position-dependent laser control is deactivated by

Name of the text file or NULL. The text file may contain one or more tables.
As a pointer to a \0-terminated ANSI string.
Determines which table in the text file is to be loaded. The parameter
corresponds to the extension <No> of
beginning of the desired table.
As an unsigned 32-bit value.
Description
Success. The absolute value of the return value is equal to the number of valid
data points found in the table. Invalid entries are ignored, see also
