Peak Power drives
Variants for applications with high load peaks and increased starting torque offer higher overload capacity (up to 200% / 60 s), increased current limits and optimized control algorithms for dynamic loads.

SPOD — Parallel connection
Up to three COMBIVERT F6 units can be paralleled (System of Parallel Operated Devices) for higher power ratings with intelligent load distribution and common control; commissioning aligns with standard F6 drives.

High-speed drives
High-speed variants support output frequencies up to 2000 Hz for spindles, turbo blowers and similar high-speed applications when combined with appropriate filters.

Applications

• Material handling, warehouse logistics, cranes
• Plastics machinery (extrusion, injection molding)
• Packaging and food processing machines
• Woodworking machinery
• Turbo compressors, high-speed blowers
• Lift and escalator drives (including regenerative systems)
