DYNAMIXEL RX-28
2-3. Dynamixel Wiring
Pin Assignment The connector pin assignments are as the following. The two connectors on the
Dynamixel are connected pin to pin, thus the RX-28 can be operated with only one
connector attached.
( Note : The pin number of connector’s edge cut side is PIN1)
PIN1: GND
PIN2: VDD(12V~21V)
PIN4: D-
PIN3: D+
PIN4: D-
PIN3: D+
PIN2: VDD(12V~21V)
PIN1: GND
Wiring Connect the RX-28 actuators pin to pin as shown below. Many RX-28 actuators can be
controlled with a single bus in this manner.
Control Box “CM-2
Main Controller To operate the Dynamixel actuators, the main controller must support RS485 UART. A
proprietary controller can be used, but the use of the Dynamixel controller CM-2 PLUS is
recommended.
