Synchronous frequency inverter COMBIVERT G6

asynchronousthree-phasesingle-phase

Product overview
The COMBIVERT G6 is a modular frequency inverter for controlled applications in the power range 0.75 kW to 30 kW. It drives asynchronous three-phase motors and synchronous servo motors in regulated operation, including sensorless modes. The platform offers uniform behaviour across power classes and integrates communication options and safety functions for industrial automation.

Highlights

• Consistent functionality across the entire power range
• Controlled V/f operation and regulated operation without encoder feedback
• Suitable for asynchronous and synchronous motors
• Available with multiple fieldbus options
• Integrated safety technology and network filter
• Adaptable to a wide range of industrial applications

Software features

• V/f and U/f functionalities
• Regulated operation without encoder (asynchronous / synchronous)
• Brake handling and DC braking
• Customer parameter groups and eight switchable parameter sets
• PID controller and power-off handling
• Additional application-specific functions

Sensorless control (SCL / ASCL / ASiCL)
Sensorless closed-loop operation delivers high dynamics and stable speed under load fluctuations using ASCL, SCL and ASiCL algorithms. ASiCL ensures excellent shaft performance and high torque at low speeds; the motor model can support subordinate positioning tasks.

Fieldbus & Technology
EtherCAT: support for CoE and EoE, CiA402 drive profile and FSoE for safety.
VARAN: real-time Ethernet suited to injection moulding and plastics applications.
Functional safety: integrated functions for monitoring speeds and positions; supports safe communication via FSoE or ProfiSafe and enables certain sensorless safety functions in certified configurations.

Applications

• Intralogistics (warehouse systems, cranes)
• Woodworking and material handling machines
• Packaging and food industry machinery
• Plastics industry (extrusion, injection moulding)
• Lifts and escalators
