Profileur de came servo Lenze série 9300 EVS9325-CKV003 5,5 kW

Product Overview

The EVS9325-CKV003 (EVS9325-CKV003) is a high-performance electronic cam profiler from the Lenze 9300-Series, engineered to replace traditional mechanical cams with a programmable, high-precision motion control solution. With a rated power of 5.5 kW, this servo controller is specifically designed for complex, non-linear motion sequences often found in automated packaging, beverage filling, and textile manufacturing. By utilizing the EVS9325-CKV003, industrial operators can achieve millisecond-accurate synchronization between multiple axes, significantly reducing mechanical wear and enabling rapid format changes without hardware reconfiguration. Although this series is currently in its phase-out stage, the EVS9325-CKV003 remains a cornerstone for maintaining high-torque legacy systems, providing a robust IP20-rated protection and the exceptional dynamic response characteristic of German-engineered Lenze motion technology.

Technical Configuration

The EVS9325-CKV003 features the specialized "CKV" cam profiling firmware, which allows the drive to execute sophisticated motion laws internally, based on a master encoder or virtual master signal. This hardware architecture is optimized for high-density cabinet installation, featuring a 13.50 cm wide chassis and an integrated forced-air cooling system to manage the thermal demands of 5.5 kW continuous operation. The drive supports a wide range of feedback systems—including resolvers and various encoder types—and integrates seamlessly into multi-axis DCS or PLC-led networks via the standard CAN system bus. Its power stage is designed for high overload capacity and precise torque linearity, ensuring that even complex acceleration and deceleration ramps in the cam profile are executed with maximum fidelity and minimal positioning error.

Technical Specifications

Technical FAQs

What is the functional difference between the CKV and standard ESV versions?

The CKV model includes an integrated cam profiler firmware that stores and executes electronic cam discs. While the ESV version is a standard servo inverter for speed and position control, the CKV version is required for applications that need non-linear synchronization, such as flying shears or rotary knives.

How does the CKV003 handle synchronization across multiple axes?

Synchronization is managed via the Lenze system bus (CAN). The master position is broadcast to all slave drives (like the EVS9325-CKV003), which then calculate their specific position based on the programmed cam table, ensuring zero mechanical backlash between synchronized components.

What are the options for parameterization for this phased-out model?

Parameters can be configured using the Lenze Global Drive Control (GDC) software or via the plug-in keypad module. For rapid maintenance, parameter sets can be saved and transferred to replacement units to minimize downtime.

Engineering & Installation Guide

To ensure long-term reliability of the EVS9325-CKV003, it must be mounted vertically in a control cabinet with a minimum clearance of 100 mm above and below the unit for unobstructed airflow. For high-precision camming applications, electromagnetic compatibility (EMC) is critical; ensure that all encoder and system bus cables are shielded and separated from the high-voltage motor power lines. The motor cable shield must be grounded using a 360-degree clamp at the drive’s EMC plate to prevent high-frequency noise from inducing jitter in the cam profile. In applications involving high-inertia braking, an external braking resistor is mandatory to prevent DC-bus overvoltage. During commissioning, perform a motor identification (auto-tuning) run to calibrate the drive to the motor's electrical model, which is essential for achieving the high torque dynamics required for complex camming cycles.
