GL646USB
The resolution of motor speed control is 16 bits, so, we can control vertical resolution
By one dpi increment, the resolution can be from 1 DPI to 4800DPI for 1200DPI scanner
And 1 DPI to 9600 DPI for 2400dpi scanner.
Note: The resolution of quarter step can up to four times resolution.
6.20. Acceleration/Deceleration Double Table
The acceleration/deceleration slope tables are store in DRAM, can be download by S/W.
The slope can be programmed by S/W for each table. Resolution is 16 bits pixel-time. The number of slope steps is
1~255 steps. One table is for scanning The other is for fast move.
The forward and backward steps can be programmed by S/W. The resolution is 16 bits pixel-time. The number of
slope steps is 1~255 steps. You can adjust any non-linear curve.
Note: what is fast move Such as move back to go home or move to window any position to scan.
(1). Two table moving :
