Product Description: The S400 (S300/S400) family is Kollmorgen’s previous-generation high-performance digital servo drive. “S403” = 3 A continuous, 400 V class (3-phase 208–480 VAC input). “AM” = specific I/O & feedback connector config. “SE” = SERCOS interface (fiber-optic ring) for real-time multi-axis motion.
Detailed content
Specifications:
-
Input Voltage: 3× 208–480 VAC (typical 400 V version for EU/export)
-
Continuous Current: 3 A rms
-
Peak Current: 9 A rms (typ. 2–3 s)
-
Power: ~1.1 kW @ 400 V
-
Feedback: Resolver, Incremental encoder (TTL/HTL), SinCos, SFD (early gen), some EnDat with option
-
Control: SERCOS (IEC 61491) cyclic data exchange; also supports analog torque/velocity mode if jumpered
-
I/O: Configurable digital inputs/outputs per S400 standard
-
Operating Temp: 0…45 °C
-
Protection: IP20, short-circuit / overtemp / overload protected
-
Dimensions: Compact bookshelf style, similar footprint to AKD but deeperNotes: Legacy product — successor is AKD series. Requires SERCOS master (KAS or compatible motion controller). Not plug-and-play with AKM motors via AKD auto-detect — manual motor parameter entry required.
