The lowercase letters j, k, l, m, and n designate the IR and DM area words
for the programming examples in this section. The Position Control Unit is
mounted on word n for output and word n+1 for input. The value n depends
on the mounting position of the Position Control Unit. The following DM area
entries for commands and positioning actions should be cross-referenced to
programming examples that follow. Refer to the formats for commands (
