ASDA-A3
Connecting multiple servo drives:
(1) Connect to the controller / PLC
(2) Modbus/CAN connector (part name: ACS3-CNADC3)
(3) Wiring for CAN / RS-485 terminal resistor (part name: ACS3-CNTRC3)
Note:
1. This supports up to 32 axes via RS-485 with the CANopen cable length of up to 30 m. The
communication quality and the connectable axes are determined by the controller's specifications,
quality of wires, grounding, interference, and whether twisted-pair cable with shielding is used.
2. It is suggested to use a terminal resistor of 120 Ω (Ohm) and 0.5 W (or more).
3. To connect multiple servo drives in parallel, please use CAN/RS-485 connectors as shown above, and
put the terminal resistor in the last servo drive.
