Changing to CS1W/CJ1W-NC271/471/F71
from CS1W/CJ1W-
NC113/133/213/233/413/433
The settings and methods for using CS1W/CJ1W-NC271/471/F71 Position Control Units include those that are
different from the pulse-output models (CS1W/CJ1W-NC113/133/213/233/413/433).
The following information is important when replacing equipment that uses pulse-output PCUs and pulse-input
Servo Drives or Stepping Motor Drives with the CS1W/CJ1W-NC271/471/F71 PCU and MECHATROLINK-II-
compatible Servo Drive.
Installation
• The FNY-NS115 MECHATROLINK-II I/F Unit must be installed when using an R88D-WT
@
OMRON W-
series Servo Drive (without built-in MECHATROLINK-II communications). The FNY-NS115 is installed on
the right side of the Servo Drive, so make sure that sufficient space is provided around the Servo Drive.
• R88D-WT
@
W-series Servo Drives must be Ver.39 or later. The Servo Drive must be changed if an earlier
version is being used. The Servomotor, power cables, and encoder cables, however, can be used as is
without changing.
Wiring
• MECHATROLINK-II Cables are used for the connection between the PCU and Servo Drive (MECHA-
TROLINK-II I/F Unit). The cables for pulse-output PCUs and Servo Relay Units cannot be used.
• The external sensor signals, such as limit inputs and origin proximity inputs, are connected to the Servo
Drive's control I/O connector (CN1). The Servo Drive's CN1 connector must be wired.
• Emergency stop input signals are not provided as external input signals for the PCU or Servo Drive. To
ensure safety in the system, provide safety measures in external circuits (i.e., not in the Programmable
Controller or Position Control Unit), such as using a breaker for the Servo Drive's main circuit power supply.
• To perform an origin search, the origin proximity input signal must be used. Make sure that the dog width of
the limit input signal and origin proximity input signal remains at the length of the MECHATROLINK-II com-
munications cycle or longer.
System Configuration
Pulse-output PCUs are classified as CS/CJ-series Special I/O Units, whereas CS1W/CJ1W-NC271/471/F71
PCUs are classified as CS/CJ-series CPU Bus Units. Make sure that the PCU's unit number is not already
used by another CPU Bus Unit and that the area allocated to the PCU in the PLC is not occupied by another
Unit.
