6.2.2. Programmable Indexer Positioning
l
Programmable Indexer Positioning means executing an indexing motion program that is stored
in program channels of the Driver Unit. The RUN input starts an indexing motion programmed
in a channel specified by the PRG0 to PRG5 inputs.
l
Activate the Motor servo. (SVON input is ON.)
l
Select a channel to be executed. (Input of PRG0 to PRG5 signals)
l
Turning the RUN input ON executes the program of selected channel while the IPOS output is
being closed.
l
During positioning of the Motor, another input of RUN command will not be accepted.
l
Execution of the SP command may start the built-in program. (The same function as RUN input
ON)
Inputting SPm ENT (m--- program channel number) will start the program of
Channel m.

The number of selectable channels by PRGx differs with the type of Driver Unit and its
parameter setting. See Table 6-5 for the selectable number of channels.
