Main communication port connector (PORT IN)
A connector for receiving the communication cable from a dedicated teaching pendant or external
equipment. It also receives a controller link cable when two or more axes are connected.
[6]
Regenerative resistor connector (RB)
A connector for regenerative discharge resistor.
The controller will come with a regenerative resistor if the specified actuator capacity is 30 W or above.
However, connection is basically optional, and it should be connected when a regenerative discharge error
occurs. The error code of the regenerative discharge error is “0C9.”

Power/emergency-stop terminal block
EMG: Both terminals are used to connect an emergency-stop switch.
(EMG terminals are short-circuited at default.)
24V: Connect the positive side of the 24-VDC power supply.
This becomes the common terminal for the PIO input circuit
N: Connect the negative side of the 24-VDC power supply.
This becomes the common terminal for the PIO output circuit.
[8] LEDs
RDY (green): Indicate that the CPU is operating normally.
RUN (green): This LED turns on while the actuator is moving.
The LED also turns on when the voltage of the absolute-data backup battery
drops.
ALM(red): This LED remains lit while an alarm is present.
ENC (orange): This LED turns on when the encoder cable is open or otherwise the encoder
cannot be recognized.
[9]
Encoder/brake connector (ENC)
An encoder/brake (optional) cable connector.
[10]
PIO connector (PIO)
A PIO cable connector.
[11] Piano switches (SW)
There are six piano switches. The role of each switch is shown below.
Piano switch number Role
6 FWP: Write protect switch
5 ABS-CLR: Absolute data clear switch (absolute specification)

Actuator address setting switches
Note: All piano switches are designated as Nos. 1, 2, etc., from the bottom.
With the piano switch in front of you, tilt it to the right side to turn on the switch, or tilt it to the left
side to turn off the switch.
