Key Technical Specifications (S406 – 400 V class, 6 A):
  • Main Supply:​ 3 × 208 – 480 VAC (typical 3 × 230/400 VAC), 50/60 Hz; also available in 115/230 VAC 3-phase for lower-current variants
  • Continuous Output Current:​ 6.0 A RMS
  • Peak Output Current:​ 12 – 18 A RMS (depending on variant/timing)
  • DC Bus:​ Internal, supports bus-sharing across multiple S400 drives
  • Control Modes:​ Torque, Velocity, Position (via analog ±10 V, Pulse/Direction, or fieldbus)
  • Feedback Supported:​ Resolver, Incremental Encoder, SinCos, EnDat, Hiperface, SFD
  • Fieldbus / I/O:​ CANopen (DS301/DS402), RS-232 setup; ±10 V analog in, digital I/O configurable
  • Switching Frequency:​ 8 / 16 kHz selectable
  • Protection Class:​ IP20 (panel mount)
  • Operating Temp:​ 0 °C … +45 °C (derated to +55 °C)
  • Dimensions (approx.):​ Book-style ~60 mm width, DIN rail mountable
  • Certifications:​ CE, UL, cUL, RoHS
Features & Benefits:
  • Master-slave internal bus allows up to 7 expansion axes from one master—minimizes wiring.
  • Fully programmable via Kollmorgen WorkBench / ServoStar software.
  • Integrated EMC filter (on most AC-input versions).
  • Good price/performance ratio for multi-axis machines.
Applications:​ Converting & packaging lines, woodworking machinery, material handling, general-purpose automation, labeling machines.
Installation & Notes:
  • Install in grounded enclosure; separate power and signal wiring.
  • If DC-bus sharing, connect all drive DC-link terminals in parallel with appropriately sized cable.
  • Verify motor winding voltage matches drive bus configuration (320 VDC or 640 VDC max bus).
