Explanation of function and operation
1. 16-bit operation (ABSD)
In this example, outputs are controlled to ON or OFF by one rotation (0 to 360
°
using the rotation angle signal
of 1
°
/pulse).
The current value
of the counter is compared with the data table with "n" lines starting from
(which occupies "n" lines
×
2 devices), and consecutive "n" outputs starting from
are controlled to ON or
OFF during one rotation.
