CAUTION
4. Initial Parameter Settings at Startup
After applying power, at least the three parameters specified below must be set in accordance with
the specific application.
Inappropriate settings of these parameters will prevent the controller from operating properly, so
exercise due caution.
For details on how to set the parameters, refer to “Parameter Settings” in the operation manual for
the PC or teaching pendant.
[1] Selecting the PIO pattern
This controller provides six PIO pattern types to meet the needs of various applications.
To select a desired type, set a corresponding value from 0 to 5 in parameter No. 25 (PIO pattern
selection).
The factory setting is “0 [Positioning mode (standard type)]."
Parameter No.

Feature of PIO pattern
0 Positioning mode (standard type)
A basic type supporting 64 positioning points and two zone outputs.
* How to set zone boundaries within which to output a zone signal:
Zone boundaries are set using parameter Nos. 1 and 2 for one zone output, and in
the position table for another zone output.
1 Teaching mode (Teaching type)
In this type, 64 positioning points and one zone output (boundaries are set in the
position table) are supported.
In addition to the normal positioning mode, the user can also select the teaching
mode in which the actuator can be jogged via commands from a PLC and the
current actuator position can be written to a specified position.
(Note 1) Jog commands from a PLC are also accepted in the positioning mode.
(Note 2) Positions can be rewritten by approximately 100,000 times.
2 256-point mode (256-point type)
The number of positioning points is increased to 256, so only one zone output is
available (boundaries are set in the position table).
3 512-point mode (512-point type)
The number of positioning points is increased to 512, so no zone output is available.
4 Solenoid valve mode 1 (7-point type)
The number of positioning points is limited to seven to offer separate direct
command inputs and position complete outputs for respective positions.
PLC ladder sequence circuits can be designed easily.
5 Solenoid valve mode 2 (3-point type)
Use of the controller as an air cylinder is assumed in this type.
Position complete output signals function differently in this type, compared to the
Solenoid valve mode 1 (7-point type).
Specifically, the signal functions not only to “indicate position complete,” but also to
“detect a position” in the same manner as auto-switches of an air cylinder.
