The operations of two tool posts are programmed independently of each
other, and each program is stored in program memory for each tool post.
When automatic operation is to be performed, each tool post is activated
after selecting a program for machining with tool post 1 and a program
for machining with tool post 2 from the programs stored in program
memory for each tool post. Then the programs selected for the tool posts
are executed independently at the same time. When tool post 1 and tool
post 2 need to wait for each other during machining, the waiting function
is available (Section 21.2)

Simultaneous operation of the two tool posts or the
operation of only a single tool post can be selected by
pressing a key on the machine operator’s panel. For details,
