IAI America ERC - Manual (Page 5)

CAUTION
2. Basic Parameter Settings
When the power is input for the first time, at least the two parameters specified below must be set in
accordance with the intended application.
If these parameters are not set properly, the ERC will not function correctly. So, pay due attention to
ensure the parameters are set properly.
For details on the setting method, refer to the “parameter settings” of the PC or teaching pendant.
[1] PIO pattern selection
This controller provides three PIO (parallel I/O) patterns to support various applications.
To select a desired PIO pattern, set a number between “0” and “2” in parameter No. 25 (PIO pattern
selection).
The factory setting is “0.”
[2] Enabling/Disabling the Pause Signal (*STP)
The pause signal uses the contact b logic to provide a failsafe function.
Therefore, this signal must remain ON in normal conditions of use.
Since there are applications where this signal is not used, a parameter is provided to disable the pause
signal so it doesn’t have to be turned ON.
To select a desired setting, set “0” or “1” in user parameter No. 15 (Pause input disable selection).
Setting
Enable (use) the signal 0
Disable (do not use) the signal 1
The factory setting for this parameter is “0: [Enable].”

Feature of the PIO pattern
0
8 points
The basic pattern providing eight positioning points.
1
3 points (air cylinder)
Use of the ERC as an air cylinder is assumed in this pattern.
The number of positioning points is limited to three, but a direct
command input and a position complete output are provided for each
target position in line with the conventional practice of air cylinder control.
This lets the user control the ERC just like an air cylinder.
2
16 points
The number of positioning points is increased to 16.
However, the home return input is not provided.
