LENZE 8101E.5C.21 Frequency Inverter, Reliable Speed Control

The LENZE 8101E.5C.21 is aimed at industrial users who require stable, repeatable and safe speed regulation for three-phase asynchronous motors. Part of the 8100E series, this frequency inverter meets the needs of production lines, pumping systems, ventilation and conveyor applications, where precise speed control is essential for product quality and continuous operation. The 8100E platform stands out by offering vector control or V/f depending on configuration, configurable acceleration and deceleration ramps, and integrated protections against overcurrent, overvoltage and undervoltage. The 8101E.5C.21 reference is a specific variant of this range, frequently used for modernising or replacing existing installations equipped with Lenze 8100 drives. You therefore benefit from a proven solution that is technically consistent with your current standards, enabling rapid deployment to limit unplanned downtime.

Controlled regulation, improved operational efficiency

• Process stability – Vector control or V/f, depending on the 8100E configuration, delivers consistent speed holding, ensuring steady quality in sensitive applications.
• Reduced mechanical stress – Configurable acceleration and deceleration ramps limit jerks, reduce wear and extend the lifetime of the drive train.
• Equipment protection – Current limiting and overvoltage/undervoltage protections help maintain overall equipment availability.
• Easy integration – The 8100E series is widely deployed in industry. The 8101E.5C.21 fits easily into existing architectures for a fast return to service.
• Streamlined maintenance – Clear parameterisation and easy replaceability reduce intervention time and help standardise your maintenance practices.

Technical architecture of the 8100E series

The LENZE 8100E range covers standard industrial applications from low to medium power, with an indicative span of approximately 0.25 kW to 2.2 kW within the series. The relevant models use three-phase supply and can operate with vector control or V/f depending on the chosen configuration. Typical built-in functions include acceleration and deceleration ramps, current limiting, thermal protection and overvoltage/undervoltage protection. Depending on model and options, the inverter can offer I/O suited to control tasks, as well as integration interfaces for automation. The 8101E.5C.21 inherits this robust, proven design. It is particularly suitable for like-for-like replacements or controlled upgrades when securing functional compatibility and preserving field operators' familiar procedures is a priority.

Typical applications and use cases

The LENZE 8101E.5C.21 is suitable for applications such as pumps, fans, conveyors and production machines where precise speed adjustment optimises energy efficiency, quality and throughput. It meets the expectations of maintenance teams, system integrators and engineering departments looking for a reliable, easy-to-operate inverter that is readily available to bring a stopped installation back online. In retrofit contexts, it provides a pragmatic migration path while limiting the need for extensive requalification.
