3.5 Signal (device) explanations
For the I/O interfaces (symbols in I/O division column in the table), refer to section 3.7.2.
In the control mode field of the table
The pin No.s in the connector pin No. column are those in the initial status.
(1) Connector applications
Connector Name Function/Application
CN1A Connector for bus cable from
preceding axis.
Used for connection with the controller or preceding-axis servo amplifier.
CN1B Connector for bus cable to
next axis
Used for connection with the next-axis servo amplifier or for connection of the cap.
CN2A A-axis encoder connector Used for connection with the A-axis servo motor encoder.
CN2B B-axis encoder connector Used for connection with the B-axis servo motor encoder.
CN4 (Note) Battery unit
connection connector
When using as absolute position detection system, connect to battery unit.
Before connecting a battery unit, turn off the power and wait for 15 minutes or more
until the charge lamp turns off. Otherwise, an electric shock may occur. In addition,
always confirm from the front of the servo amplifier whether the charge lamp is off or
not. Replace the battery unit with main circuit power OFF and with control circuit power
ON. Replacing the battery with the control circuit power OFF results in loosing absolute
position data.
CN5 Communication connector The personal computer is connected.
Note. A battery unit is a unit that has eight MR-BAT batteries inserted in an MR-BTCASE battery case.

Forced stop EM1 CN3-10 Turn EM1 off (open between commons) to bring the motor to an forced stop
state, in which the base circuit is shut off and the dynamic brake is operated.
Turn EM1 on (short between commons) in the forced stop state to reset that
state.
When parameter No.PA.04 is set to " 1
", automatically ON (always
ON) can be set inside.
