LENZE EVS9329-EI, 9300 series brushless controller for precise, long-lasting axis control

Designed for industrial environments where process stability admits no compromise, the LENZE EVS9329-EI is a brushless controller from the 9300 series that ensures precise control of synchronous motors and AC servomotors. Powered by 380-480 V 3AC, it delivers a rated power of around 30 kW, positioning it as a robust solution for demanding applications. Its IP20 design is optimised for integration in a ventilated control cabinet. The unit fits into a modular automation architecture, with code-based parameterization and command-word configuration, thermal overload management and advanced protection functions. For both maintenance and engineering, it offers a documented balance of control performance, electrical safety and fast commissioning. SEI supports you with short lead times and flexible services to secure your line start-ups and restarts.

Measurable performance and operational continuity

• Stable speed and torque control – Maintains accuracy under load for consistent product quality and reduced scrap.
• 380-480 V 3AC network compatibility – Compatible with standard industrial power distribution, simplifying electrical design.
• Rated power around 30 kW – Torque reserve for decisive accelerations and short cycles on heavily loaded axes.
• Built-in protections and diagnostics – Prevents thermal faults, enables fast root-cause identification and reduces downtime.
• Reproducible code-based parameterization – Easy duplication of settings, machine-to-machine consistency and simplified maintenance.

Robust architecture, electrical safety and high-quality control

The EVS9329-EI brushless controller is based on LENZE's 9300 platform, known for reliable closed-loop control and consistent configuration tools. The IP20 rating targets installation in a ventilated electrical cabinet, with controlled airflow for dependable thermal performance. The unit is designed for circuits able to deliver up to 5000 A rms symmetrical at 480 V max, subject to appropriate upstream protection, which enhances system safety. Protection functions include thermal overload management, supply fault handling and internal monitoring, limiting the risk of damage to the motor and drive. Interfaces enable integration into automation architectures via fieldbus for coherent data exchange with the control system and centralized supervision. The whole package supports structured commissioning and reproducible settings.

Typical uses and application environments

This brushless controller is intended for highly stressed motion axes such as dynamic conveying, palletising, bagging, winding, multi-robot axis positioning, assembly tooling and machining centres that require fast response. Maintenance managers and automation engineers benefit from stable control, clear parameterization and effective diagnostics to secure start-ups, maintain throughput and extend equipment lifetime.

Technical differentiation and reliability of the LENZE 9300 range

The 9300 series stands out for a mature software base, proven control functions and clear documentation—key factors to reduce engineering time and secure operations. Modularity makes it easier to adapt to the application, while internal protections limit damage in the event of faults.
