This document describes the CANopen communication protocol for Altivar 312 variable speed drives. It covers hardware configuration, software configuration, and signal description.
This manual covers safety precautions, installation warnings, and the required procedures before working on the Altivar 312 drive. It emphasizes the need for qualified personnel, proper grounding, and discharge of DC‑bus capacitors to prevent electric shock, explosion, or arc‑flash hazards.
The document then describes the hardware setup for CANopen daisy‑chain and tap options, configuration and signalling, software setup, and the complete object dictionary with parameter definitions. It also lists the RJ45 connectors, termination requirements, and the impact on bus length when using the daisy‑chain option.
