CAUTION
1. Basic Setting of User Parameters
After applying power, at least the three user 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 user parameters, refer to “User Parameter Settings” in the operation
manual for the PC or teaching pendant.
(1) Selecting the PIO pattern
This controller provides five 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 4 in user parameter No. 25 (PIO
pattern selection).
The factory setting for this parameter is “0: [Conventional].”
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 user 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.
(2) Enabling/disabling the servo ON input signal (SON)
The servo ON input signal has been added to allow for servo ON/OFF control on the PLC side.
Depending on the needs, therefore, the user must enable/disable this signal.
Setting
Enable (use) the signal
0
Disable (do not use) the signal
1
If “0” or “2” has been selected as the above PIO pattern, the servo ON signal is not provided.
However, you must still set “1: [Disable]” in Parameter #21 (SON). (If “0” is set, the servo will not turn
ON.)
The factory setting for this parameter is “1: [Disable].”
