- Auto-Tuning: One-button auto-tuning with advanced notch filter and Bode plot analysis for rapid machine commissioning.
- SFD Feedback: Kollmorgen’s Smart Feedback Device enables single-cable motor connection, eliminating separate encoder wiring and reducing installation cost.
- Safe Torque Off (STO): Integrated SIL 2 / PLd safety function — no external safety relay required for basic safety circuits.
- EtherCAT Performance: 250 µs cycle time with distributed clocks for tight multi-axis synchronization.
- Compact Footprint: Narrow 40 mm width enables high-density cabinet layouts.
System Architecture & Signal Flow
The S7240F-NAF2NA-NA-035 operates within a closed-loop servo architecture:
- Command Input: EtherCAT master (PLC/motion controller) → AKD drive via RJ45
- Power Stage: 240 VAC input → internal rectifier → DC bus → IGBT inverter → motor output
- Feedback Loop: Motor encoder/SFD → drive DSP → real-time current/velocity/position correction
- Safety Channel: STO input (24 VDC) → hardware disable of IGBT gate signals (SIL 2)
- I/O Interface: Digital inputs for enable/fault reset; analog input for velocity/torque reference in standalone mode
