Contrôleur servo Lenze série 9300 EVS9327-ES 15,0 kW

Product Overview

The EVS9327-ES (EVS9327ES) is a high-performance 9300-series servo inverter engineered for precision motion control in demanding industrial environments. As a versatile 15.0 kW drive, it serves as the backbone for high-torque applications in packaging machinery, textile production, and synchronized material handling systems. By providing exceptional dynamic response and high-speed accuracy, this unit plays a critical role in minimizing cycle times and reducing unplanned downtime in automated facilities. Its IP20 protection class is specifically optimized for control cabinet integration, offering a compact footprint for high-density electrical installations. Even as this series enters the phase-out stage, the EVS9327-ES remains a vital component for maintaining the legacy performance of global manufacturing lines.

Technical Configuration

The EVS9327-ES architecture is built upon Lenze’s proven 9300-series platform, featuring integrated "Global Drive" technology. This allows for seamless parameterization and modular expansion. The unit supports sophisticated control loops including speed control, torque control, and position tracking. Communication is facilitated through standard system bus (CAN) interfaces, enabling real-time coordination between multiple axes. The internal hardware includes robust IGBT power stages and specialized heat dissipation pathways designed to maintain thermal equilibrium during continuous high-load operations. Its modular software structure allows for specific function blocks to be loaded, making it adaptable to complex motion profiles without requiring external PLC processing power.

Technical Specifications

Technical FAQs

Is the EVS9327-ES compatible with newer Lenze motor generations?

Yes, the 9300-series supports a wide range of asynchronous and synchronous motors. However, feedback parameters and resolver settings must be precisely configured in the Global Drive Control (GDC) software to ensure optimal torque characteristics.

How do I address a 'CE0' (Communication Error) on the display?

A CE0 fault typically indicates a timeout on the system bus. Check the CAN termination resistors (120 Ohm), verify the baud rate settings across all nodes, and ensure that the shielded communication cables are separated from high-voltage motor leads.

What is the recommended replacement path as this model is in Phase-Out?

While direct stock is often available for maintenance, the long-term migration path involves the Lenze i950 or 9400 HighLine series. Note that physical dimensions and wiring terminals differ, necessitating a cabinet layout review.

Engineering & Installation Guide

• Thermal Management: Ensure a minimum vertical clearance of 100 mm above and below the unit. Since the EVS9327-ES dissipates significant heat at a 15.0 kW rating, forced cabinet ventilation is mandatory to prevent internal junction over-temperature trips.

• EMC Compliance: To prevent electromagnetic interference, use 360-degree shielded motor cables. The shield must be clamped to the mounting plate using a metal conductive clip rather than a simple pigtail connection to ensure a low-impedance path for high-frequency noise.

• Braking Resistor Integration: For high-inertia loads or rapid deceleration cycles, an external braking resistor must be connected to terminals +UG and BR. Verify that the resistance value matches the minimum allowable Ohmic value specified in the Lenze hardware manual to avoid damaging the internal brake chopper.
