1) Write the following data to to +2n-1 in advance by a transfer instruction:
For example, store rising point data and falling point data alternately.
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 +2n − 1.
2. 32-bit operation (DABSD)
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 present value of the counter is compared with the data table 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.
