(1) I/O devices
POINT
The devices not indicated in the Connector Pin No. field of the I/O devices
can be assigned to the connector CN1A/CN1B using the Servo
Configuration software.
In the factory setting state, Forced stop (EMG) and Automatic/manual
selection (MD0) are not assigned to the pins but are preset to turn on
automatically.

Functions/Applications
Forced stop EMG Turn EMG on to bring the motor to an Forced stop state, in which the servo is
switched off and the dynamic brake is operated.
Turn EMG off in the Forced stop state to reset that state.
In the factory setting state, Forced stop (EMG) is preset to turn on automatically.
(Refer to Section 6.6 (2) (c).)
Servo-on SON CN1B-19 Turn SON on to power on the base circuit and make the servo amplifier ready to
operate (servo-on).
Turn it off to shut off the base circuit and coast the servo motor (servo off).
Reset RES CN1B-15 Turn RES on for more than 50ms to reset the alarm.
Some alarms cannot be deactivated by the reset signal. Refer to Section 11.2.1.
Turning RES on in an alarm-free status shuts off the base circuit. The base circuit
is not shut off when "
1 " is set in parameter No. 55.
Since this device is not designed for stopping. Do not switch it on during operation.
