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.

SMARTSTEP Junior Servo Drive I/O Signals (R7D-ZN
@
-ML2 with
Built-in MECHATROLINK-II Communications)
This section describes the standard I/O signals used with a Position Control
Unit when using a SMARTSTEP Junior Servo Drive with Built-in MECHA-
TROLINK-II Communications.
Refer also to the
SMARTSTEP Junior Servo Drive with MECHATROLINK-II
Communications User’s Manual
(Cat. No. I554).
Terminal Arrangement of Control I/O Connector (CN1)
The default control I/O signal allocations for a SMARTSTEP Junior Servo
Drive with MECHATROLINK-II Communications are set to the standard Servo
Drive settings for using MECHATROLINK. The default pin arrangement of the
control I/O connector (CN1) on the Servo Drive are shown below.
Only the I/O signals that are connected to the Position Control Unit are shown.
Refer to
6-4 Standard Settings for Servo Drives Using MECHATROLINK
for
the standard Servo Drive settings for using MECHATROLINK.
Note
(1) Do not connect unused pins.
