Profileur de came servo Lenze série 9300 EVS9329-EK 30,0 kW

Product Overview

The EVS9329-EK (EVS9329-EK) is a high-capacity electronic cam profiler from the Lenze 9300-Series, engineered to deliver sophisticated motion control in high-torque industrial applications. Delivering a robust 30.0 kW of rated power, this servo controller is designed to replace traditional mechanical cams with programmable, high-precision electronic motion laws. In heavy-duty B2B sectors—such as large-scale rotary cutters, high-speed bottling lines, and heavy-duty metal forming presses—the EVS9329-EK provides the dynamic response and millisecond-accurate synchronization required for complex, non-linear motion sequences. This "EK" variant features specialized firmware for cam profiling, allowing for rapid format changes and reduced mechanical wear. Although the 9300-Series is in its phase-out stage, this German-engineered unit remains a cornerstone for maintaining and upgrading high-power legacy automation systems where reliability and torque density are paramount.

Technical Configuration

The EVS9329-EK architecture is optimized for high-power cabinet installation, featuring a 30.0 kW power stage housed in a 35.00 x 25.00 x 25.00 cm frame. The integrated "EK" cam profiling firmware enables the drive to execute complex motion profiles internally, driven by a physical master encoder or a virtual master signal via the System Bus. The hardware is designed with an IP20 degree of protection and includes forced-air cooling to manage the thermal loads of a 30.0 kW continuous output. It supports a wide range of feedback systems, including high-resolution resolvers and SinCos encoders, ensuring that the executed cam profile maintains maximum fidelity even under high-load acceleration. The modular interface allows for seamless integration into multi-axis DCS or PLC networks using CANopen, PROFIBUS, or other common industrial protocols.

Technical FAQs

How does the "EK" cam profiling firmware differ from standard positioning firmware?

The EK firmware is specifically designed for non-linear synchronization. While standard positioning drives follow a point-to-point path, the EVS9329-EK follows a mathematical "cam disc" relationship between a master and slave axis, allowing for variable speed ratios and complex motion cycles within a single revolution.

Can the EVS9329-EK handle high-inertia regenerative braking?

Yes. For a 30.0 kW unit handling significant loads, the drive utilizes an internal brake chopper. However, to safely dissipate the energy generated during the deceleration of high-inertia cam cycles, a correctly sized external braking resistor is mandatory.

What is the recommended replacement path for this phased-out 30.0 kW model?

Since the 9300-Series is in phase-out, original new or refurbished units are best for direct replacement without cabinet redesign. For new system planning, the Lenze 9400 HighLine or the i700/i950 series are the modern technological successors, though these require updated engineering and mounting configurations.

Engineering & Installation Guide

For the EVS9329-EK, vertical mounting in a well-ventilated control cabinet is essential to manage the heat generated by the 30.0 kW power stage. Ensure a minimum clearance of 100 mm above and below the unit for unobstructed airflow. To maintain the precision of the electronic camming, all encoder and system bus cables must be high-quality shielded twisted pairs, grounded at the drive's EMC plate using 360-degree clamps. Given the 12.50 kg weight, the mounting plate must be rigid and grounded to the common machine earth to prevent electromagnetic interference from affecting the high-resolution feedback signals. During commissioning, use Lenze Global Drive Control (GDC) software to upload and verify the cam tables, ensuring that the slave axis synchronization is perfectly aligned with the master reference signal.
