EVS9325-EPV004 Lenze 9300-Series 5.5kW Servo Position Controller

Product Overview

The EVS9325-EPV004 (EVS9325-EPV004) is a high-performance 5.5 kW servo position controller from the established Lenze 9300-Series, specifically designed for precision motion control in complex automation architectures. This module is engineered to handle demanding positioning tasks in sectors such as high-speed labeling, material handling, and rotary indexing tables. By integrating an internal positioning control system, the EVS9325-EPV004 alleviates the processing load on the master PLC, ensuring rapid response times and high-resolution accuracy. Although currently in the phase-out stage, this 5.5 kW controller remains a critical component for maintaining high-productivity assets, offering a reliable path for system continuity in plants that require exact synchronization and robust torque management to minimize mechanical wear and operational downtime.

Technical Configuration

The EVS9325-EPV004 architecture is centered on a flexible, function-block-based internal structure, allowing for highly customized motion profiles. It operates with a rated power of 5.5 kW and features an IP20-rated enclosure, optimized for vertical installation within control cabinets. The unit supports various feedback systems and is equipped with integrated protection functions against short circuits, earth faults, and motor overloads. With physical dimensions of 35.00 x 25.00 x 13.50 cm and a weight of 7.50 kg, it provides a powerful drive solution in a standardized form factor. The "EPV" designation signifies its specialized "Positioning" firmware variant, which includes dedicated logic for point-to-point positioning, homing functions, and sophisticated travel profile generation, making it a versatile tool for sophisticated machine designs.

Technical FAQs

How does the EVS9325-EPV004 manage internal positioning tasks?

The EVS9325-EPV004 features a dedicated positioning control software variant. It allows the user to store multiple target positions and travel profiles directly in the drive, which can be triggered via digital I/O or a fieldbus interface, reducing the need for high-speed counter modules in the PLC.

Can I still obtain spare parts for this phase-out model?

Yes, while in the phase-out period, we provide original "Brand New" or fully tested "Refurbished" units. These units serve as direct replacements to ensure legacy production lines remain operational without the immediate need for expensive cabinet redesigns.

What cooling precautions are necessary for the 5.5 kW power stage?

The unit utilizes forced-air cooling. It is essential to ensure that the air intake and outlet are not obstructed. In environments with high ambient temperatures, maintain a 100 mm vertical clearance and monitor the heatsink temperature via the internal diagnostic parameters to avoid thermal shutdown.

Engineering & Installation Guide

Control Cabinet Thermal Strategy:

The EVS9325-EPV004 is an IP20-rated device and must be installed in a clean, dry environment. For a 5.5 kW load, the drive dissipates significant thermal energy. Ensure the cabinet's cooling system is rated for the cumulative heat loss of all installed drives. If mounting multiple 9300-series units side-by-side, maintain a minimum horizontal gap of 10 mm to ensure adequate lateral airflow and prevent localized hot spots.

Wiring and Shielding for High-Resolution Positioning:

To maintain the integrity of the positioning data, all encoder and feedback cables must be double-shielded and routed separately from the 400 V power lines. Use a minimum separation distance of 20 cm. The motor cable shield must be grounded at both ends—directly at the drive's shielding plate and at the motor terminal box—using low-impedance EMC clamps to prevent signal jitter.

Braking Energy Management:

In applications involving high inertia or vertical movements (e.g., hoists), the DC bus voltage may rise rapidly during deceleration. It is critical to verify the sizing of the external braking resistor. Ensure the resistor is mounted externally to the drive's direct airflow path to prevent heat transfer back into the power electronics, and always use heat-resistant wiring for the brake chopper connection.
