8105E.6A.21 - Frequency Converter - LENZE

Lenze 8105E.6A.21, variable frequency drive for asynchronous motors

This variable frequency drive is aimed at maintenance managers, automation engineers and integrators looking for a stable, proven solution to control asynchronous motors at variable speed. The Lenze 8105E.6A.21 converts the supply frequency to finely adjust speed and torque according to process requirements. It stands out for its straightforward installation, easy cabinet integration and the reliability associated with Lenze industrial ranges widely deployed. For installed fleets and equipment facing obsolescence, this model offers a pragmatic answer that extends machine life while securing availability. Paired with Standard Exchange Industry services, you gain quick access to a refurbished or new supply depending on availability, or to a repair, limiting costly downtime and restoring drive performance with a short lead time.

Speed control, service continuity, costs under control

• Process stability – Frequency variation allows the motor speed to be matched to the load, improving cadence regularity and reducing production variability.
• Reduced mechanical stress – Acceleration and deceleration ramps, typical of industrial drives, limit jolts and protect gearboxes, transmissions and guidance elements.
• Operational energy efficiency – Speed adjustment helps reduce consumption on variable-torque applications such as ventilation or pumping while maintaining the required service level.
• Quick integration – Compact format for control cabinet mounting and parameter philosophy consistent with Lenze ranges, enabling fast familiarization by your teams.
• Delivery assurance – Thanks to SEI stock and network, availability in 24 to 72 h depending on stock, reducing line downtime.

Proven architecture and industrial integration

The 8105E.6A.21 is part of Lenze's family of drives for standard three-phase asynchronous motors. Its frequency conversion principle ensures precise speed control for common drive uses. The format is designed for control cabinet integration, with clear wiring and a layout that follows industrial best practices. Depending on configuration, standard Lenze drive functions are available, such as discrete and analog control inputs, ramp-up and ramp-down functions, and control modes suited to light automation tasks. Parameterization can be done via a local keypad or a software tool on certain versions, making it easy for your technicians to adjust key settings. The design follows an industrial robustness approach, with standard drive protection features such as monitoring of electrical parameters and appropriate reactions to exceedances to protect the motor and power electronics.

Typical applications in industrial environments

The Lenze 8105E.6A.21 meets the needs of variable-speed drive applications in material handling, packaging, food processing and utilities. It is particularly relevant for conveyors, transfer tables, dosing systems, fans and pumps, as well as for light automation requiring simple, reliable speed control. Engineering offices and maintenance departments use it to modernize existing installations, optimize energy consumption and improve motion quality without heavy reconfiguration.
