## Driver Compatibility
– ✅ Native compatibility: **Kollmorgen AKD, S700 (Servostar700)** – driver hardware must support resolver interface.
– ⚠️ Standard encoder-based drivers **cannot directly drive this motor** due to incompatible interface hardware.
Lifecycle Status
– EOL – Original manufacturer discontinued, NRND – Not recommended for new designs**
– Market availability: Refurbished, used, or limited stock spare parts; no new factory orders available.
– Next-generation replacement: AKM2G-42; ⚠️ Mechanical dimensions, connectors, and feedback interfaces **are not directly interchangeable**—requires reselection, rewiring, and parameter tuning.
Typical Applications
Packaging machinery, machine tools, material handling, industrial automation equipment; suitable for high-vibration and dusty environments where load holding via brake is required upon power loss.
