2. Set data
3. Applicable devices
S
: "D
.b" cannot be indexed with index registers (V and Z).
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 365
°
) of the table (using the rotation
angle signal of 1
°
/pulse).
The current value
of the counter is compared with the table data 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.
