Control

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.

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.
