4) Axis No. Setting Switch (ADRS)
This switch is used to set an axis number in multi-axis operation through serial communication.
Using the SIO converter allows multiple axes to be controlled on a teaching tool such as a PC
without connection/disconnection of the connection cable connector. The SIO converter can
specify up to 16 axes with hexadecimal numbers 0 to F. [Refer to 10.1.3 Axis No. Setting]
The setting of the switch is read at power-on of the controller. Changing the setting after the
power-on is invalid.
Caution: Note duplicate axis number setting, which causes a communication error
(alarm code 30C: no connection axis error) to occur and disables normal
communication.
5) Piano Switch
Not to use.
6) Motor Connector (MOT) [Refer to 2.2.3 [4] Motor • Encoder Circuit]
It is a connector to connecting the motor encoder cable of the actuator.
7) Regenerative Unit Connector (RB) [Refer to 2.2.3 [6] Circuit of Regenerative Units]
It is a connector to connecting regenerative unit.
8) Internal Regenerative Resistor Valid Connector
Short-circuit cable is connected at delivery.
Caution: Make sure to use the unit in the condition that the short-circuit cable is
connected.
Use the unit without this connected may damage the device.
9) Charge Status Display LED
It shows the status of electric charge in the controller.
Caution: While this LED lamp is on, do not attempt to touch controller or
regenerative resistor units to prevent electric shock.
