Caution
● At occurrence of an alarm in the release level, RES can reset the alarm. Cancel the
remaining moving distance after confirmation that alarm signal *ALM (being ON in
normal state and OFF at occurrence of an alarm) is set to ON.
* Refer to [8.3.3 Alarm Details] for details of alarms.
● Turning *STP OFF with the actuator being in the positioning complete state causes
PEND to be turned OFF. Note that this situation may not occur when a sequence
program is created. It is not an emergency stop output due to an alarm generation of the
controller.

4.2.6 Direct Position Specification (Operation of PIO Pattern 4 and 7)
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.

Note • Speed change is not allowed during movement.
• For incremental type, 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.
• In the battery-less absolute or simple absolute type, if it gets into a condition that the
home-return operation is incomplete due to such a reason as a parameter change,
operation to the indicated position number would not be performed, but only the
home-return operation should be performed.
