Connection
6.3 Grounding
The wire used to ground the motor and driver must be as thick and short to the grounding point as possible so that no
potential dierence is generated. Choose a large, thick and uniformly conductive surface for the grounding point.
z
Grounding the motor
Connect the grounding wire along with a
set screw to the grounding point, using a
shakeproof washer.
For the 15 W type motor, remove the paint from
the mounting surface of the geared motor, and
install it to a metal surface that has grounded.
z
Grounding the driver
Install the driver to a metal surface that
has grounded.
6.4 Connecting the I/O signals (CN2)
Insert the connector of the I/O signal cable into the I/O signal connector (CN2) of the driver.

Description
14 Yellow/Black DIN0 [START/STOP]
These signals are used to operate the motor.
The motor rotates according to the acceleration time when both the
START/STOP input and the RUN/BRAKE input are turned ON.
If the START/STOP input is turned OFF, the motor stops according to the
deceleration time. If the RUN/BRAKE input is turned OFF, the motor stops
instantaneously.
13
Orange/
White
DIN1 [RUN/BRAKE]
12 Red/White DIN2 [FWD/REV]
This signal is used to change the motor rotation direction.
The motor rotates in the forward direction when the signal is turned ON.
*2
11 Brown/White DIN3 [M0]
The operation data number can be selected based on a combination of
ON-OFF status of the M0 and M1 inputs.
10 Black DIN4 [M1]
9 White DIN5 [ALM-RST]
This signal is used to reset the alarm.
(The alarm will be reset at the ON edge of the input.)
8 Gray VH
External analog
setting device
*3
These terminals are used when the rotation speed or torque limiting
value is externally set using an external analog setting device (external
potentiometer or external DC voltage).
7 Purple VM
6 Blue VL
5 Green GND GND I/O signals common
4 Yellow DOUT0 [SPEED-OUT] 30 pulses are output while the motor output shaft makes one revolution.
3 Orange DOUT1 [ALM-B]
This is a signal to output an alarm status.
It is turned OFF when an alarm is generated. (Normally closed)
2 Red DOUT2 [TLC] This is a signal to output when the motor output torque is limited.
*4
1 Brown DOUT3 [DIR]
This is a signal to output information of the motor rotation direction.
(It is turned ON when the motor rotates in the forward direction.)
*1
A signal assigned at the time of shipment is described in brackets [ ]. Functions for the pin No.1 to No.4 and No.9 to No.14
can be changed using the MEXE02.
*2
The rotation direction of the output shaft varies depending on the gear ratio of the gearhead.
The rotation direction can be changed by setting of the "Motor rotation direction" parameter.
*3
If the "External setting method" parameter is changed, the rotation speed and torque limiting value can be set with the
PWM signal input.
*4
The torque limiting value is set to 200% at the time of shipment and can be changed using the MEXE02.
