TROLINK communications cycle. If the input signal width is shorter than
the communications cycle, the Position Control Unit will be unable to de-
tect the input signal.
(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.

G-series Servo Drive I/O Signals (R88D-GN
@
-ML2 with Built-in
MECHATROLINK-II Communications)
This section describes the standard I/O signals used with a Position Control
Unit when using a G-series Servo Drive with Built-in MECHATROLINK-II
Communications.
Use the
OMNUC G Series AC Servomotors/Servo Drives with Built-in
MECHATROLINK-II Communications User's Manual
(Cat. No. I566) together
with this manual for information on I/O signals.
Terminal Arrangement of the Control I/O Connector (CN1)
When using G-series Servo Drives with built-in MECHATROLINK-II communi-
cations, 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 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.
