EVS9326-EKV004 Lenze 9300-Series 11kW Servo Cam Profiler

Product Overview

The EVS9326-EKV004 (EVS9326-EKV004) is a high-performance servo cam profiler belonging to the sophisticated Lenze 9300-Series, engineered to replace mechanical cams with flexible, software-based motion profiles. Delivering a rated power of 11.0 kW, this controller is a critical asset for complex multi-axis synchronization in industries such as high-speed bottling, rotary printing, and synchronized material handling. By utilizing the EVS9326-EKV004, engineers can achieve rapid format changes and precise electronic gearing, significantly reducing mechanical wear and setup times. Despite its official phase-out status, this German-manufactured drive remains a primary solution for maintaining legacy automation cells where high torque density and millisecond-accurate camming profiles are essential for operational continuity and minimizing production bottlenecks.

Technical Configuration

The EVS9326-EKV004 is architected as an "EKV" variant, specifically optimized for electronic cam (cam profiler) functionality. It features an IP20-rated chassis designed for centralized control cabinet installation. The hardware supports high-resolution feedback systems and is capable of managing complex motion laws through its internal processing unit. This drive integrates seamlessly into master-slave architectures via the system bus (CAN), allowing for real-time synchronization between multiple axes. Its power stage is built for high overload capacity, ensuring stable performance during the rapid acceleration and deceleration phases typical of camming cycles. Furthermore, the 9300-Series architecture facilitates easy diagnostic testing and parameterization through the Global Drive Control (GDC) software interface.

Technical FAQs

What is the primary application advantage of the Cam Profiler (EKV) version?

The EKV version allows for the storage and execution of complex non-linear motion profiles (electronic cams) internally. This eliminates the need for expensive and inflexible mechanical cam discs, enabling the machine to switch between different production recipes at the touch of a button.

How should I handle the phase-out status of this product for a critical system?

As the EVS9326-EKV004 reached its official end-of-life in 2017, we recommend maintaining local spare parts inventory or consulting with our technical team for potential migration paths to the 9400-series or i950-series while ensuring software compatibility for the cam profiles.

Is external braking resistance required for this 11 kW drive?

For applications involving high-inertia loads or rapid deceleration (common in camming), an external brake resistor is highly recommended to dissipate regenerative energy and prevent DC-bus overvoltage faults.

Engineering & Installation Guide

To ensure the longevity of the EVS9326-EKV004, maintain a minimum vertical clearance of 100 mm from adjacent components to allow for unobstructed airflow through the IP20 chassis. When configuring the electronic cam, ensure that the "Master" signal (whether from a virtual master or an external encoder) is shielded using low-capacitance twisted-pair cabling to prevent jitter in the cam profile. For safety, the integration of an external mains contactor and fast-acting semi-conductor fuses is mandatory to protect the power stage from short-circuit events. In environments with high ambient temperatures, monitor the internal heatsink temperature via the drive's diagnostic parameters; if it consistently exceeds 45 deg C, auxiliary cabinet cooling must be implemented to prevent premature aging of the electrolytic capacitors.
