Design and Performance
High-Precision Multi-Feedback Motor Control
A two-channel multi-encoder interface supports an exceptionally broad range of feedback devices — incremental, resolver, Hiperface, SinCos, SSI, EnDat, and BiSS — allowing this drive to precisely control synchronous, asynchronous, IPM, high-torque, high-speed, and synchronous reluctance motors from a single platform.
Real-Time EtherCAT Communication
Built-in EtherCAT/CAN fieldbus connectivity with CiA 402 device profile support enables real-time, deterministic communication with a higher-level controller, suited for coordinated multi-axis motion applications.
Integrated Safety and Braking
Onboard Safe Torque Off (STO) functionality provides a certified safety stop function without external safety relays, while the integrated brake transistor and 24V/2A brake control support direct connection of a mechanical holding brake.
Higher Power Class Than the F6-Kompakt 37kW Variant
Delivering 45 kW / 90 A, this housing-4 unit extends the F6-Kompakt range beyond the 37 kW housing-3 variant (20F6K13-3411), supporting larger motors while retaining the same fieldbus, encoder, and safety feature set.
Robust Overload and Peak Current Handling
With a 150% current controller limit and a 180% cut-off threshold, the 21F6K14-3411 handles demanding starting torque and transient load conditions common in industrial machinery.
