Lenze EVS9328-ESV004 9300-Series Servo Inverter

Product Overview

The EVS9328-ESV004 (EVS9328-ESV004) is a high-performance servo inverter from the Lenze 9300-series, engineered for precision motion control in demanding industrial automation. Rated at 22.0 kW, this unit is designed to handle high-torque applications with superior dynamic response, making it a critical component for production lines, high-speed material handling, and complex multi-axis synchronization systems. By ensuring accurate speed and position regulation, the EVS9328-ESV004 provides the consistency required to minimize mechanical fatigue and unplanned downtime in mission-critical electrical and automation infrastructure.

Technical Configuration

The hardware architecture of the EVS9328-ESV004 is optimized for continuous duty within protected control cabinets, featuring an IP20-rated enclosure. It utilizes advanced flux vector control to manage induction or synchronous servo motors, providing exceptional torque control from standstill up to base speed. The controller includes high-speed processing capabilities for handling complex motion tasks and integrates seamlessly with common fieldbus systems via modular communication cards. Its internal logic is designed to monitor vital parameters—such as DC-link voltage, heat sink temperature, and output current—in real-time, facilitating proactive fault detection and ensuring stable operation even under varying load profiles.

Technical Specifications

FAQs

Is the EVS9328-ESV004 backwards compatible with older 9300-series installations?

The 9300-series platform is highly modular. If you are replacing an existing unit, ensure the firmware version and parameter settings are migrated using the current engineering toolset to maintain compatibility with your machine's motion profile.

What is the recommended approach for thermal management?

As this unit is rated for 22.0 kW, proper cabinet ventilation is essential. Ensure a minimum of 100 mm of clearance above and below the drive to facilitate airflow, and ensure that the internal cabinet fans are sized to dissipate the drive's heat loss under full load.

Can this drive be operated without an external braking resistor?

The drive contains an internal braking transistor. Depending on your application's deceleration requirements and inertia, you may need to connect an external braking resistor to prevent over-voltage trips during rapid stop cycles.

Why is this model designated as 'Phase-Out'?

Lenze is transitioning to newer drive generations with enhanced diagnostic features. We continue to support the 9300-series, but we recommend long-term maintenance planning that includes evaluating modern replacements for future system upgrades.

Installation Guidelines and Best Practices

• Shielding for EMI Suppression: To ensure compliance with industrial EMC standards, use a 360-degree shield connection for the motor cable at both the motor terminal box and the drive's earth connection. This reduces radiated emissions and prevents high-frequency noise from affecting control signal integrity.

• Torque and Connectivity: Verify that all power terminals are tightened to the torque values specified in the manual. Loose connections on high-power drives are a primary cause of terminal block degradation and potential arcing.

• Environment and Safety: Ensure the unit is installed in a clean, non-conductive environment to prevent dust buildup on the internal heat sink fins. Before powering the system, confirm that the motor and encoder cables are properly routed and that the drive's enable inputs are configured to fail-safe in the event of an emergency stop trigger.
