1) Write in advance the following data to
to
+2n+1 by a transfer instruction:
For example, store the 16-bit rising point data to an even device number devices, and store the 16-bit
falling data to an odd device number devices.
2) Output pattern
When the command input is set to ON, "n" points starting from
change as shown below.
Each rising point/falling point can be changed respectively by overwriting the data in
to
+n
×
2.
2. 32-bit operation (DABSD)
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 present value
of the counter is compared with the table data having "n" lines starting from
[
+1,
] (which occupies "n" lines
×
4 devices), and consecutive "n" outputs starting from
are
controlled to ON or OFF during one rotation.
