Product Overview

The EVS9330-EKV004 (EVS9330EKV004) is a heavy-duty, high-capacity Servo Cam Profiler from the prestigious Lenze 9300-Series. Engineered for high-demand industrial applications, this 45.0 kW controller specializes in the digital replacement of mechanical cams, providing unparalleled flexibility in complex motion synchronization. In large-scale operations such as heavy metal forming, industrial printing presses, and high-volume bottling plants, the EVS9330-EKV004 serves as the central intelligence for precise torque delivery and position control. Its ability to manage significant power loads while maintaining extreme accuracy makes it a cornerstone for reducing mechanical wear and optimizing machine throughput. As a critical phase-out component, it is highly sought after by maintenance professionals to sustain the operational life of large-scale automated lines without the prohibitive costs of a full system overhaul.

Technical Configuration

The EVS9330-EKV004 is built on a high-power architecture designed to handle intensive current cycles. The "EK" designation signifies the integrated Cam Profiler functionality, while the "V004" suffix indicates a specific hardware or software revision typically tailored for enhanced ventilation or specialized factory settings. This unit features a sophisticated internal bus system that supports rapid communication between the motion profile generator and the power stage. It is housed in a robust IP20 chassis and includes comprehensive protective circuits for overvoltage, earth faults, and motor short circuits. The controller’s firmware allows for real-time calculation of complex non-linear curves, ensuring smooth transitions even under the high-inertia loads common in 45.0 kW applications.

Technical FAQs

What are the primary advantages of the "EK" cam profiling over standard servo control?

The "EK" variant allows for the storage of complex motion profiles directly on the drive. This enables the machine to execute intricate non-linear movements and synchronization with a master encoder without requiring a high-level PLC to process every motion step, significantly reducing network latency.

Can the EVS9330-EKV004 be used in high-vibration environments?

While rated IP20, this unit is a heavy-duty controller. However, for installations near high-impact machinery like stamping presses, it must be mounted in a vibration-isolated cabinet. The internal high-power components and 36.50 kg mass require a rigid, reinforced mounting backplane.

Does this model support regenerative braking?

Yes, the 9300-Series at this power level typically requires an external brake resistor to dissipate energy during rapid deceleration of high-inertia loads. Internal monitoring protects the drive from DC-bus overvoltage during these cycles.

Engineering & Installation Guide

• Handling and Mounting: Due to its significant weight of 36.50 kg, the EVS9330-EKV004 requires mechanical lifting assistance during installation. It must be mounted vertically on a load-bearing surface. Use M8 or equivalent high-tensile bolts and ensure the mounting plate is unpainted at the contact points to provide a high-quality EMC ground reference.

• Thermal Management: At a 45.0 kW rating, thermal dissipation is a critical factor. Ensure a minimum of 150 mm clearance above and below the unit. Forced-air cooling within the enclosure is mandatory; the ambient air temperature must not exceed 40 Celsius to maintain peak performance without automatic current limiting.

• Power Connectivity: Use high-temperature rated, shielded power cables for motor connections. Ensure that the PE (Protective Earth) conductor is sized correctly according to local electrical codes for a 45.0 kW load to manage potential fault currents and reduce high-frequency interference.
