(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.
Name
The position deviation is less than positioning comple-
tion range 1 (Pn500). (This signal is always OFF in con-
trol modes other than position control mode.)
This is the holding brake timing signal that is output
according to the settings in parameters Pn506, Pn507,
and Pn508.
Turned ON if there are no errors after the control and
main circuit power supplies are turned ON.
This output turns OFF when there is a Servo Drive
alarm.
Use this terminal to connect the cable's shield and FG
wire.

Di: Diode providing surge-voltage protection (Use a high-speed diode.)
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.)
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.
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.
