KEB's Combivert F6 VFD is offered through 450kW and incorporates the latest drive technology. Flexibility and performance are the main focus and the units are offered with various communication, functional safety, heatsink, and control card options.
Product Details
The F6 is offered in graduated sizes up to 450 kW. Both 230V and 480V classes are available with switching frequencies up to 16kHz.
Multiple control card options are available depending on application requirements. All drives feature dual-channel STO inputs and SM3 supports advanced Functional Safety modes including Failsafe over EtherCAT (FSoE).
The F6 supports EtherNet/IP, EtherCAT, Modbus TCP/IP, ProfiNet, and Powerlink communication protocols. The F6 operates a wide variety of motor types including induction, AC PM Servo, Linear, Torque, and Synchronous Reluctance motors. Motor modes and communication is software selectable.
Additionally, the F6 supports a variety of different cooling types. Forced air (fan cooled) is standard but push through and liquid-cooled heatsinks are also available.

Functional Safety
KEB's F6 VFDs offer safety functions that you can configure. For straightforward setups, use digital inputs/outputs (I/Os) to manage safety features. For more complex systems, the drive supports advanced safety protocols like "Safety over EtherCAT" (FSoE) or PROFIsafe. These protocols provide flexible control over safety functions and limit values, helping ensure your system operates safely and reliably.
• Available for the entire COMBIVERT F6 power range
• Safety functions can be used with or without encoders
• Up to eight safety configurations per function
• For operating various motor technologies such as ASM, PM, IPM, SyncRel
• Safety functions certified to SIL 3 in accordance with IEC 61508, or to PL e in accordance with ISO 13849
• Safety over EtherCAT (FSoE) or PROFIsafe safety profile
• Fast release times
