[7] Direct Position Specification (Solenoid Valve Mode 1) = Operation of PIO Pattern 4
The start signal is provided for every position number. Only turning ON the relevant input signal
according to the table shown below allows the operation based on the data in the target
position number to be performed. The operation mode is called the solenoid valve mode
because solenoid valves can directly drive air cylinders.
At the completion of positioning, every completed position number is output as well as the
positioning complete signal.
Positioning, pressing, and pitch feed are possible. Their control methods are the same as those
of other patterns.

If start signal ST* is issued without home return, the home return operation is
automatically done before the operation based on the data of the specified
position number. When this specification is not desired, interlock by home return
complete signal HEND is required.
