EVS9322-EKV004 Lenze 9300-Series 0.75kW Servo Cam Profiler

Product Overview

The EVS9322-EKV004 (EVS9322-EKV004) is a high-precision electronic cam profiler from the Lenze 9300-Series, engineered to replace mechanical cam discs with programmable, dynamic motion profiles. Delivering a rated power of 0.75 kW, this servo controller is specifically designed for complex motion sequences in packaging, printing, and textile machinery where rapid synchronization and high-speed cycle times are required. By utilizing the EVS9322-EKV004, operators can implement intricate motion laws and "on-the-fly" adjustments, significantly reducing machine changeover times and mechanical stress. Although this series reached its official phase-out in 2017, the EVS9322-EKV004 remains a critical legacy component for maintaining high-precision automation lines, offering reliable IP20-rated protection and the robust German engineering standards characteristic of the Lenze 9300-Series architecture.

Technical Configuration

The EVS9322-EKV004 is optimized for "EKV" cam profiling, featuring an integrated internal processing unit capable of executing complex non-linear motion tasks based on a master encoder or virtual master signal. This drive supports versatile feedback options and communicates via the standard system bus (CAN) to coordinate with other drives in multi-axis configurations. The hardware is housed in a slim 7.80 cm chassis, allowing for high-density installation in electrical cabinets. Its power stage is built for high dynamic response, facilitating precise torque and position control essential for camming operations. The unit's design also emphasizes ease of diagnostics, supporting parameterization through Lenze’s GDC software or plug-in keypad modules for rapid field commissioning and troubleshooting.

Technical FAQs

What are the primary benefits of using an electronic cam profiler like the EVS9322-EKV004?

Electronic camming eliminates the physical wear and vibration associated with mechanical cams. It allows for limitless profile adjustments via software, enabling the machine to handle diverse product formats without mechanical reconfiguration, thus increasing overall machine flexibility and throughput.

Can the EVS9322-EKV004 operate in a master-slave configuration?

Yes. The 9300-Series servo drives are specifically built for synchronization. The EVS9322-EKV004 can act as a slave following a master position signal transmitted over the CAN bus or via high-speed digital pulse-direction interfaces.

What should be considered regarding its Phase-Out status?

Since the 2017 phase-out, new units are increasingly rare. It is highly recommended to source "Brand New" original stock to ensure longevity. For future system upgrades, our technical team can assist in mapping existing cam profiles to newer Lenze i950 or 9400 HighLine platforms.

Engineering & Installation Guide

To ensure optimal performance of the EVS9322-EKV004, it must be mounted vertically in a clean, dry environment within the cabinet to maintain its IP20 rating. Ensure a minimum vertical clearance of 100 mm for effective thermal convection. For cam profiling accuracy, use shielded, low-capacitance cables for all encoder and communication signals to prevent electromagnetic noise from causing position jitter. The motor cable shield must be grounded at both the drive's EMC plate and the motor terminal box using 360-degree clamps. Before operation, verify that the DC bus links are correctly fused if sharing energy between multiple drives. During commissioning, perform a motor identification run to ensure the servo controller’s internal model perfectly matches the motor’s electrical characteristics for maximum torque linearity.
