EVS9323-EP - Position controller - LENZE

Lenze EVS9323-EP brushless controller - 9300 series

The benchmark brushless controller EVS9323-EP is part of the Lenze 9300 series, designed for drive applications requiring reliable control of speed, torque and position. Engineered for precise control of synchronous brushless servomotors and asynchronous motors, this servo drive meets the demands of machine tools, conveyor systems and packaging equipment where trajectory tracking, repeatability and process stability are critical. Its architecture allows cabinet mounting with a 400 V AC three-phase supply, or via a DC bus when the axis is integrated into a multi-axis architecture. Certified electrical characteristics, regulatory compliance and an IP20 protection rating make it a controlled solution for industrial B2B environments. Advanced motion control functions combined with positioning features help reduce cycle times and improve product quality, while facilitating maintenance through structured, reproducible parameterization.

Overview of the Lenze 9300 series

The 9300 series groups brushless controllers and servo drives designed for precise motion control in process and machinery industries. It addresses the needs of single or coordinated axes, from indexed conveying to cyclic positioning operations. The platform emphasizes control stability, positioning repeatability and service continuity. In cells controlled by a programmable logic controller (PLC) or by numerical control (CNC), the 9300 delivers deterministic motion profiles with controlled speed transitions and consistent torque management from acceleration through to controlled stop. The option to supply the axis from a 450 to 620 V DC bus simplifies integration in compact multi-axis setups where centralized energy management is sought. Reliable positioning and the maintenance of angular or linear tolerances improve the quality of repetitive operations while reducing mechanical wear thanks to smooth, predictable control.

Built for demanding industrial environments, the range provides structured configuration mechanisms useful for maintenance teams and automation engineers during replacement, optimization or restart after an incident. As a variable frequency drive dedicated to servomotors, this series supports both synchronous brushless axes and asynchronous motors, offering flexibility for installed fleets and progressive equipment upgrades.

Industrial applications

This brushless controller EVS9323-EP integrates into many drive architectures where precision and repeatability are priorities.

• Machine tools : axis positioning operations, controlled feeds and auxiliary functions requiring managed dynamics
• Conveying : indexing, axis synchronization and rate control of loads on automated lines
• Packaging : repetitive motion profiles, belt traction and coordinated insertion operations
• Automated assembly : precise tooling movement, pick-and-place and reliable transfers
• Material handling : control of translation and lifting axes with torque management under load

In these use cases, closed-loop control of speed, torque and position contributes to cycle consistency and reduces synchronism errors. The power rating of 1.5 kW and nominal current of 3.9 A suit medium-sized axes while preserving operating margin thanks to the specified maximum currents.

Integration and communication

The EVS9323-EP is designed for cabinet integration on a 400 V three-phase network. Depending on the chosen topology, a 450 to 620 V DC bus supply enables compact multi-axis assemblies. The control functions support motion coordination managed by the line PLC, with seamless use of speed, torque or position references provided by the higher-level controller. Communication cards and extension modules available within the 9300 range, depending on configuration, allow integration on common industrial fieldbuses. Commissioning is performed using the manufacturer's tools, with a parameter logic that promotes reproducibility and traceability of settings.

Monitoring and diagnostic mechanisms help assess axis condition and document key parameters, which facilitates preventive maintenance and reduces mean time to repair. EMC compliance, the Low Voltage Directive and UL E132659 approval support integration in environments subject to safety and electromagnetic compatibility requirements. The IP20 rating is suitable for closed ventilated cabinets, with the possibility of reaching IP41 when a thermal separation compliant with the manufacturer's recommendations is used.
