EVS9325-EI - Position controller - LENZE

LENZE EVS9325-EI, 9300 series brushless controller for precise industrial motion

Designed for maintenance teams, integrators and machine builders, the LENZE EVS9325-EI brushless controller from the 9300 series meets the dynamic axis control requirements of industrial environments. It drives LENZE brushless servomotors as well as asynchronous motors for positioning, speed control and torque regulation applications. Assigned to the EVS9325 family, it targets an application range of around 5.5 kW motor power and an output close to 9 kVA, typically for 400 to 480 V three-phase supplies. The 9300 architecture integrates dedicated current, torque and position loops, with extensive configuration via keypad and communication interfaces to deliver a stable, repeatable and easily tuned response. The EI variant sits within the 9325 ecosystem, with a functional level aligned with neighbouring versions in the series. For production lines the objective is clear: secure continuity of operation by ensuring precision, responsiveness and reliability.

Motion accuracy and operational availability

• Precise positioning – Dedicated control loops enable a stable, repeatable trajectory, a key factor for assembly, packaging and high-speed handling.
• Torque control – Torque management ensures controlled starts and smooth transitions, reducing mechanical wear and supporting process quality.
• Motor versatility – Compatibility with brushless servomotors and asynchronous motors optimises existing fleets and simplifies retrofits.
• Efficient commissioning – Commissioning via keypad and communication interfaces speeds up start-up and simplifies in-production adjustments.
• Continuous service ensured – With SEI you benefit from standard exchange options, new or reconditioned supply and repair services to reduce downtime and control total cost of ownership.

Control features and execution quality

Part of the 9300 series, the EVS9325-EI relies on current, torque and position regulation functions combined with field-oriented control modes adapted to driving LENZE brushless servomotors. The package is designed for dynamic behaviour with a stable response even under load variations. The operating range is around 5.5 kW motor power, for a 400 to 480 V three-phase supply and an output power close to 9 kVA, in line with the 9325 family specifications. Configuration via keypad and communication interfaces provides the level of tuning granularity required by industrial automation, from simple speed variation to complex positioning sequences. The EI variant follows the same options logic as neighbouring models in the range, with possible differences in interfaces or accessories while preserving the control fundamentals inherited from the 9300 platform.

Typical applications and use cases

The EVS9325-EI brushless controller is suitable for synchronized conveyors, bagging and forming machines, pick-and-place stations, handling or indexing systems, and assembly cells where motion repeatability and torque control directly impact quality. In modernization projects, it facilitates replacement of older drives thanks to its compatibility with brushless and asynchronous motors, while bringing the 9300 series benefits in terms of configuration and operational consistency.
