EVS9331-EI - Position controller - LENZE

LENZE EVS9331-EI, 9300 series, the brushless controller for stable, repeatable motion control

Designed for maintenance teams and system integrators who must secure the availability of their lines, the LENZE EVS9331-EI stands out as a reference brushless controller for 400 V architectures. Part of the 9300 series, it drives synchronous and asynchronous motors with precision suited to industrial cycle rates while ensuring reliable operation over long running hours. Its three-phase 400 to 480 V AC supply and approx. 55 kW power are suitable for sustained-torque motion applications and frequent starts. You get a robust device that meets the demands of modern production environments, together with Standard Exchange Industry's logistical responsiveness to minimise downtime and control total cost of ownership.

Operational benefits focused on performance and availability

• Process stability – Precise control of synchronous and asynchronous motors promotes consistent motion profiles and reliable repeatability, reducing quality drift in production.
• Proven compatibility – As part of the 9300 series, the EVS9331-EI integrates seamlessly into installations already standardised around LENZE drives, simplifying maintenance and commissioning.
• Right-sized power – With a three-phase 400 to 480 V AC supply and approx. 55 kW power, the unit meets the needs of sustained-torque applications and controlled load peaks.
• Reduced downtime – Available as standard exchange, new or refurbished, combined with 24 to 72 h shipping to accelerate equipment restart and secure the production plan.
• Cost control – With multiple sourcing options and repair services available, you optimise your maintenance budget while preserving process performance.

Key features and design quality

The EVS9331-EI is part of LENZE's 9300 servo architecture. This family is recognised for controlling synchronous brushless and asynchronous motors used in industrial automation systems. The controller is powered from a three-phase 400 to 480 V AC network, matching electrical infrastructures commonly deployed in workshops and on high-power lines. The usable power of approx. 55 kW enables drives requiring significant torque, with headroom for demanding cycles or load variations. The 9300 series design targets durable operation in industrial environments, favouring fine control to maintain cycle rates, repeatability and to reduce incidents during continuous operation. The interfaces and implementation principles are consistent with current automation practices, easing integration into an existing control cabinet and recovery of parameters during a planned or corrective replacement.

Typical uses and application contexts

This brushless controller meets the needs of sectors where motion precision and robustness are decisive. It is particularly suited to assembly modules, high-dynamics conveyors, winders, packaging lines, processing machines and axes of handling units. Target users include maintenance departments, system integrators and engineering teams looking for a reliable solution to drive synchronous or asynchronous motors in a 400 V environment with requirements for repeatability and availability.

Differentiation, reliability and LENZE support

LENZE's 9300 series is recognised in the industrial automation market for its balance between control precision and endurance in demanding environments. The EVS9331-EI follows this tradition, offering compatibility with existing installations and a limited learning curve for commissioning teams. Offered by Standard Exchange Industry, it is available as a standard exchange unit, new or refurbished, with warranties from 6 to 24 months depending on the selected service. You also benefit from professional support for selection and fast provision to secure your restart timelines.
