COMBIVERT S6
Implement new machine concepts with enhanced performance, communication and integrated safety requirements. Specifically developed for servo applications in a compact book format, the COMBIVERT S6 expands KEB’s product range. This modern, compact yet flexible servo controller is designed for a rated current of 2.6 A to 12 A, and comes in two housing sizes. The servo inverters control a wide range of motor technologies, with or without encoder operation, and – depending on the application – feature scalable, high-performance safety functions.

Functional Safety
What is the objective of functional safety? The short answer is to minimise the risks posed by technical equipment to people and the environment. Functionally safe system solutions for machines and plants are based on consistent architecture right through to the mechanical interface. Certified hardware and software isare used to simplify project planning and the development of applications with safety solutions.
COMBIVERT F6 drives offer scalable safety functions directly in the drive controller – with or without encoders. Safety functions and limit values can be flexibly adjusted via digital I/Os and/or the “Safety over EtherCAT” (FSoE) or PROFIsafe safety profile.
- Available for the entire COMBIVERT F6 power range
- Safety functions that 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

Technology
profile Position Mode CIA 402
The drive profile according to CiA402 provides a standardised platform for drive controller-based automation. This is achieved by means of the modes of operation specified in the profile, in particular also by the Profile Position Mode. The resulting relief of the PLC and cost optimisation with direct, undelayed access to the application enable economical and high-quality application solutions – consistent and manufacturer-independent.
SENSORLESS CONTROL (SCL/ASCL/ASiCL)
Sensorless closed-loop operation and maximum dynamics – without lowering speed during load fluctuations. This is made possible by KEB’s sensorless control methods ASCL (Asynchronous Sensorless Closed Loop) and SCL (Sensorless Closed Loop), regardless of whether asynchronous, synchronous, synchronous reluctance or IPM motors are involved. With ASiCL (Asynchronous single current closed loop), KEB also provides a complementary solution which ensures excellent shaft performance with high torque even in the low-speed range. The motor model also takes care of positioning during subordinate positioning tasks.
High-speed applications
Whether for asynchronous, synchronous, synchronous reluctance or IPM motors: All types of motors can be controlled and operated highly dynamically without encoders by the COMBIVERT F6 or COMBIVERT S6 drive controllers at high speeds of up to 120,000 rpm using the ASCL or SCL method. Depending on individual requirements, this is possible with or without encoder. This means that nothing stands in the way of using motors in high-speed applications.
