LENZE 8106E.4K.12, frequency inverter for precise and reliable motor control

This LENZE 8106E.4K.12 frequency inverter meets the requirements of maintenance managers, control engineers and integrators seeking a stable solution to drive asynchronous motors in industrial environments. Whether for preventive replacement, retrofit after obsolescence or urgent recommissioning, this model restores controlled speed modulation, protects downstream mechanical parts and limits energy drift. Speed regulation, shock damping and condition monitoring help reduce unplanned downtime. Backed by SEI expertise, you benefit from fast availability, options for exchange units and qualified repair, securing your operational uptime without compromising on quality.

Performance and tangible production benefits

• Speed stability – Accurate drive control promotes consistent throughput, limits quality variations and reduces rework at the end of the line.
• Smooth start and stop – Configurable ramps soften mechanical shocks, protect gearboxes, belts and couplings, and extend component life.
• Motor protection – Built-in monitoring functions help prevent overloads and overheating, securing the motor asset over the long term.
• Energy optimization – Matching speed to load improves overall efficiency and can reduce consumption on variable-torque applications such as fans or pumps.
• Simplified diagnostics – Status and fault messages make root-cause identification easier, speed up troubleshooting and minimise downtime.

Industrial design and key features

The LENZE 8106E.4K.12 is built with a robust approach suited to industrial constraints. Clearly labeled connections simplify wiring and reduce errors during on-site replacements. The core functions expected from a modern inverter are included, with parameterisation options for speed, acceleration and deceleration ramps, and current limiting to protect the installation. The unit accepts local or remote commands depending on the chosen architecture, with control inputs for start, stop and direction, and status outputs useful for machine monitoring. Configuration is structured to support reproducible commissioning and easier maintenance. LENZE's proven design targets long-term reliability, with attention to heat dissipation and immunity to electromagnetic disturbances in industrial environments.

Field applications

This frequency inverter fits a wide range of process and handling applications. It helps control conveyors to stabilise transfer speeds, regulates fans and extractors for fine flow adjustments, and supports pumps to reduce water hammer. On assembly or packaging machines, it enables smooth speed transitions to preserve production quality. It is a reliable solution when a fast replacement is required to restore a line to nominal throughput.

Why choose LENZE and SEI for this drive

LENZE is a recognised reference in electrical drives, with designs focused on stability and longevity. Coupling it with SEI services gives you responsiveness and peace of mind. Three options are offered depending on your lead time and budget: supply of new or reconditioned equipment, exchange unit to get back up and running quickly while returning the old unit, or electronic repair carried out by specialised technicians. Each service is bench-tested with traceability and benefits from a 6 to 24 month warranty depending on the chosen option. Our international logistics and multi-brand stock enable deliveries within 24 to 72 h in many cases.

Our support includes help identifying the exact reference, integration advice and compatibility information on request, to secure the replacement and minimise on-site adjustments. This reduces the risk of extended downtime and helps control your operating costs. In case of obsolescence, we assess an equivalent alternative and guide you through the transition to preserve the installation's original performance.

To speed up your recommissioning, submit your request for a quote specifying the machine environment and the LENZE 8106E.4K.12 reference. Our teams will confirm availability, propose the best option between supply, exchange or repair, and arrange express shipping. Ensure the continuity of your operations with a technical partner who understands industrial urgency and commits to quality.
