IAI America RCP2-CF - Manual (Page 4)

CAUTION
1. 24-V Power Supplies for Equipment Requiring a UL Certification
[1] The controller with the maximum current of 2 A (RCP2-C/CG) and 6 A (RCP2-CF) are UL-certified.
However, a UL certification requires that the 24-V power supplies used with the controller conform to
Class 2.
If the user’s equipment must receive a UL certification, please use an input power supply and an I/O
power supply both conforming to Class 2.
[2] RCP2 controller can be used in the environment of the pollution degree 2.
2. Basic Parameter Settings
After applying power, at least the three parameters specified below must be set in accordance with the
specific application.
Inappropriate
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 (Parallel I/O) patterns to meet the needs of various applications.
To select a desired PIO pattern, set a corresponding value from 0 to 5 in parameter No. 25 (PIO
pattern selection).
The factory setting is “0.”settings of these parameters will prevent the controller from operating properly,
so exercise due caution.
Parameter
No. 25 setting
Feature of PIO pattern
0 Conventional
This pattern is compatible with the pin assignments of the RCP controller.
1 Standard
All functions of the RCP controller are available, plus the home-return command input, servo
ON input, reset input, moving output and ready output.
2 64-point positioning
Compared with the standard pattern offering only 16 positioning points, this pattern provides up
to 64 positioning points.
However, the servo ON input, ready output and zone output have been removed.
3 2 zone output signals
Compared with the standard pattern offering only one zone output signal, this pattern provides
two zone output signals.
However, the moving output has been removed.
The boundaries for the second zone output signal are specified in parameter Nos. 23 and 24.
4 Teaching
This pattern allows for normal positioning operation, as well as jogging and writing of current
position to a specified position using I/Os.
Switching between the normal positioning mode and teaching mode is effected by the MODE
input signal.
The mode switching completion output has been added to indicate that the modes have been
switched.
However, the zone output has been removed.
(Note) Position data can be rewritten up to around 100,000 times.
5 4 points (air cylinder)
Use of the RCP2 as an air cylinder is assumed in this pattern.
The number of positioning points is limited to four, 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 RCP2 just like an air cylinder.
