External I/O Circuits
Section 3-3
(3) When selecting a sensor for the origin proximity input signal (origin return
deceleration LS), use a sensor such as a Photoelectric Sensor, which
does not have chattering, because the origin signal is detected after the
input goes from ON to OFF during the origin search. If a switch with con-
tacts is used, the origin position may shift due to the switch contact's chat-
tering.
CN1 Control Output Signals
Control Output Circuit
Note
The circuit is equipped with an auto-resetting circuit breaker to protect the out-
put. Even if an overcurrent trips the breaker, the breaker will reset automati-
cally after a certain time elapses with no current. (Ver. 37 and later Servo
Drives are equipped with the auto-resetting circuit breakers.)

W-series Servo Drive I/O Signals (R88D-WN
@
-ML2 with
MECHATROLINK-II Built-in Communications)
This section explains the I/O signals used between the PCU and a W-series
Servo Drive equipped with built-in MECHATROLINK-II communications.
Use the
OMNUC W Series User's Manual
(Cat. No. I544) together with this
manual for information on I/O signals.
Terminal Arrangement of the Control I/O Connector (CN1)
When using W-series Servo Drives equipped with built-in MECHATROLINK-II
communications, the default control I/O signal allocations are the standard
Servo Drive settings for using MECHATROLINK.
The following diagram shows the terminal arrangement of the W-series Servo
Drive's Control I/O Connector (CN1) when MECHATROLINK is being used
with the Servo Drive's default settings.
This diagram shows only the I/O signals used when connecting to the PCU.
