3. SIGNALS AND WIRING
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.
CN2 Encoder connector Used for connection with the servo motor encoder.
CN4 Battery connection connector When using as absolute position detection system, connect to battery (MR-
J3BAT).
For setting battery, make sure that charge lamp is off more than 15 minutes
after main circuit power is switched off. Then, confirm that the voltage
between P-N terminals in the tester or the like. Replace the battery 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.

Forced stop EM1 CN3-20
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.

DI1 CN3-19 DI-1
DI2 CN3-2 DI-1
DI3 CN3-12
Devices can be assigned for DI1 DI2 DI3 with controller setting.
For devices that can be assigned, refer to the controller
instruction manual. The following devices can be assigned for
Q172HCPU Q173HCPU QD75MH.
DI1: upper stroke limit (FLS)
DI2: lower stroke limit (RLS)
DI3: near-point dog (DOG)

Trouble ALM CN3-15 ALM turns off when power is switched off or the protective circuit
is activated to shut off the base circuit.
Without alarm occurring, ALM turns on within about 1.5s after
power-on.
DO-1
Electromagnetic
brake interlock MBR CN3-13 When using this signal, set operation delay time of the
electromagnetic brake in parameter No.PC02.
In the servo-off or alarm status, MBR turns off.
DO-1
In-position
(Positioning
completed) INP CN3-9 INP turns on when the number of droop pulses is in the preset
in-position range. The in-position range can be changed using
parameter No. PA10.
When the in-position range is increased, INP may be on
conductive status during low-speed rotation.
INP turns on when servo on turns on.
This signal cannot be used in the speed loop mode.
DO-1
Ready RD When using the signal, make it usable by the setting of
parameter No.PD07 to PD09.
RD turns on when the servo is switched on and the servo
amplifier is ready to operate.
