Load_Fly_2D_Table - Scanlab RTC6 PCIe Board Installation And Operation Manual

Ctrl Command load_fly_2d_table
Function Loads a 2D table from an ASCII text file for a set_fly_2d-Processing-on-the-fly application
with 2D encoder compensation for xy positioning stages, see
Compensation for xy Positioning Stages", page
NoOfDataPoints = load_fly_2d_table( 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.

exceed the range
–524,288...+524,287 (otherwise precision may be lost). During runtime, the current
encoder values (including reference values) must not exceed the largest values
specified in the table. Otherwise, clipping occurs.
• load_fly_2d_table overwrites a previously loaded table for 2D encoder compensation.
• If Name = NULL, then a 0-correction table for 2D encoder compensation is loaded and
the table is marked as invalid (see init_fly_2d).
