Describes the hardware installation and connection of Altivar 61 LonWorks ® Card
The Altivar 61 LonWorks Card adds LonWorks® network communication to the Altivar 61 variable‑speed drive. This manual explains how to install the card, connect it to a LonWorks bus, configure communication parameters, and use the provided network variables for control, monitoring and diagnostics.
Safety precautions are emphasized: power must be removed and the DC bus capacitors allowed to discharge for at least 15 minutes before any service work. Additional resources, including LonWorks resource files and plug‑in software, are available from the Schneider Electric website.
