Variateur servo série 9300 Lenze EVS9328-ES

Product Overview

The Lenze EVS9328-ES (EVS9328-ES) is a high-capacity servo inverter engineered for precision motion control within the 9300-series drive platform. Delivering a robust 22.0 kW of rated power, this unit is specifically designed for heavy-duty industrial applications, such as high-torque extrusion processes, large-scale conveyor systems, and complex material handling machinery. The EVS9328-ES provides the high-level torque regulation and speed stability required to optimize throughput while minimizing mechanical stress on production equipment. By integrating this servo controller into an automation environment, maintenance and project engineers gain a reliable tool for reducing process variability and avoiding costly system downtime, ensuring consistent operational performance even under intensive duty cycles.

Technical Configuration

The architecture of the EVS9328-ES focuses on efficient power conversion and accurate signal processing. It features an advanced control loop capable of handling demanding inertia ratios, making it well-suited for high-precision synchronization tasks. The hardware is housed in a rugged chassis rated at IP20, optimized for cabinet-integrated installations where heat management is critical. The unit supports various feedback protocols, allowing it to interface seamlessly with standard industrial encoders and resolvers. Its internal power electronics are designed for longevity, incorporating thermal monitoring and protection mechanisms that safeguard the drive and the connected motor against transient electrical faults or overload conditions, thereby maintaining system integrity in 24/7 production settings.

Technical Specifications

FAQs

Is the EVS9328-ES suitable for high-load applications?

Yes, with a rated power of 22.0 kW, this unit is specifically intended for demanding industrial loads where sustained torque and precise speed control are required.

Does the IP20 rating require specific cabinet conditions?

The IP20 rating indicates the unit is not sealed against water or fine dust. Therefore, it must be installed within a clean, climate-controlled control cabinet to prevent the accumulation of contaminants that could lead to short circuits or thermal failure.

How does this model compare to other 9300-series drives?

The EVS9328-ES is a high-power variant within the 9300-series. It utilizes the same control architecture and parameterization structure as lower-power 9300 models, allowing for consistent programming logic across a machine fleet.

Is this drive still supported for new projects?

While the series is in the phase-out stage, it remains a critical component for maintaining legacy machine performance. We offer original stock to ensure your operations can continue without the immediate need for major control system upgrades.

Installation and Operational Guidelines

• Thermal Management: Given the 22.0 kW output and 14.50 kg mass, ensure the unit is mounted vertically on a backplane with high thermal conductivity. Maintain at least 15 cm of clearance above and below the drive to facilitate proper airflow through the cooling channels.

• Wiring and Grounding: Due to high power switching, all motor cables must be properly shielded to prevent radiated EMI. The shield must be connected to the PE bus using a high-surface-area clamp rather than a simple pigtail connection, which is ineffective at high frequencies.

• Capacitor Maintenance: If this unit has been in storage for more than 12 months, the DC bus electrolytic capacitors may require a controlled reforming process. Connect the drive to a variable AC supply and gradually increase the input voltage over a period of 60 minutes to ensure safe operation.
