It connects with the drive main control unit via DDCS fiber link, serves as an optional fieldbus expansion component to access inverters into CANopen industrial bus networks for multi-drive synchronous networking, remote parameter management and coordinated motion control.Product Type: DIN rail-mounted CANopen fieldbus communication adapter, integrating DDCS fiber interface, 500V galvanically isolated CAN transceiver, hardware bus fault diagnosis, node address DIP switch configuration and watchdog safety circuit, compliant with CANopen DS301 and CiA402 drive profiles, dedicated gateway module for connecting variable frequency drives to distributed CANopen control systems.
Product Positioning
NCAN-02C 64286731 is a standard CANopen fieldbus expansion adapter for ABB drive systems. It realizes bidirectional high-speed data exchange between inverters and CANopen master stations such as PLC and motion controllers, supporting drive start/stop, speed/torque reference, status collection, fault reading and online parameter modification. The galvanic isolation design eliminates ground loop, inverter harmonic and electrostatic surge interference to prevent communication dropout and drive runaway. With multi-baud-rate adaptive and flexible node address configuration, it is widely applied in technical renovation, communication capacity expansion and spare part replacement projects for legacy frequency conversion systems in metallurgy, port, mining, thermal power and chemical industries.
Hardware Architecture
- DDCS Fiber Communication Unit: Dedicated fiber transceiver realizes isolated high-speed data interaction between the adapter and drive main controller, uploading operating data and receiving control commands.
- Galvanically Isolated CANopen Transceiver Unit: 500V opto-isolated CAN interface complying with ISO 11898-2, equipped with short-circuit, overvoltage and reverse polarity protection to suppress common-mode industrial interference.
- Node Configuration & Status Indication Unit: Hardware DIP switch for CANopen node address setting; four LED indicators display transmit, receive, network and module operating status for rapid on-site fault location.
- Watchdog Safety Monitoring Unit: Hardware watchdog automatically resets the module upon communication timeout or program exception, supporting fault latch and auto-reset safety modes with fault information uploaded to upper systems.
- DIN Rail Mounting Unit: Compact flame-retardant plastic housing with snap-on DIN rail structure, spring anti-loose terminals for reliable wiring and dense cabinet layout adaptation.

IV. Working Principle
After DC power-on, the module reads pre-configured node address and baud rate via DIP switch, completes self-test of power supply, CAN transceiver and DDCS fiber link, initializes CANopen protocol stack and waits for network access. Bidirectional data interaction is realized between the drive main controller and CAN master station through fiber and differential bus. The hardware watchdog monitors program operation; once communication or hardware fault occurs, fault latch is triggered with emergency alarm uploaded, and normal communication can be restored after troubleshooting and module reset.

- Centralized remote monitoring and torque coordinated control for port container crane variable frequency equipment.
- Distributed frequency conversion interlock and speed synchronization control for mine long-distance belt conveyor systems.
- Intelligent bus transformation for thermal power plant auxiliary fan and water pump high-voltage frequency converters.
