CAUTION
2. Basic Parameter Settings
When the power is turned on for the first time, at least the two parameters explained below must be set in
accordance with your specific application.
Remember to always set these parameters properly, because improper settings will prevent the product from
operating correctly.
For details on how to set these parameters, refer to “parameter settings” of the PC software or teaching pendant.
[1] Selecting a PIO pattern
This controller provides four PIO patterns to support various applications.
To select a desired pattern, set the corresponding number between 0 and 3 in parameter No. 25 (PIO pattern
selection).
The factory setting is “0.”
Setting of parameter No.
25
Features of PIO pattern
0
8 points
The basic pattern providing eight positioning points.
1
3 points (air cylinder)
This pattern assumes that the actuator is used in place of an air cylinder.
The number of positioning points is limited to three, but a direct command
input and a position complete output are provided separately for each target
position in line with the conventional practice of air cylinder control.
This lets you control the actuator just like an air cylinder.
2
16 points (setting by zone boundary parameters)
The number of positioning points is increased to 16.
The boundaries defining the output range of the zone signal are set by
parameters.
3
16 points (setting in zone fields in the position table)
The number of positioning points is increased to 16.
The boundaries defining the output range of the zone signal can be set
differently for each position in the position table. Accordingly, this pattern is
ideal for applications where the setup is changed from time to time.
[2] Enabling/disabling the pause signal (*STP)
The pause signal is provided as a contact-b signal to enable fail-safe action.
Therefore, this signal must remain ON during normal conditions of use.
Since there are applications where this signal is not necessary, however, a parameter is provided to
enable/disable the signal so that you need not turn ON the signal every time.
To enable or disable the pause signal, set “0” or “1” in user parameter No. 15 (Pause input disable selection).
Setting
Enable (Use) 0
Disable (Do not use) 1
The factory setting is “0: [Enable].”
