7.15 Drum sequence
7.15 Drum sequence
16-bit binary data absolute method
ABSD
This instruction creates many output patterns corresponding to the current value (16-bit binary data) of a counter.
■Descriptions, ranges, and data types
■Applicable devices
*1 Only C can be used.
*2 T, ST, C cannot be used.
• In this example, outputs are controlled to on or off by one table rotation (0 to 360 using the rotation angle signal of 1/
pulse).
• The current value (s2) of the counter is compared with the data table with "n" lines starting from (s1) (which occupies "n"
lines 2 devices), and consecutive "n" outputs starting from (d) are controlled to on or off during one rotation.
