Lenze EVS9324-EKV004 9300-Series Servo Cam Profiler (3.0 kW)

Product Overview

The EVS9324-EKV004 (EVS9324 EKV004) is a high-precision Servo Cam Profiler from Lenze’s sophisticated 9300-Series. Rated at 3.0 kW, this drive is specifically engineered to replace mechanical cams with flexible, software-based electronic cam profiles. It is an essential component for applications requiring complex synchronized motion, such as flying saws, rotary cutters, and high-speed packaging machinery. Featuring an IP20 protection rating for cabinet installation, the EVS9324-EKV004 offers a proven, robust architecture for master-slave synchronization. Although this series is currently in its phase-out stage, it remains a gold standard for maintaining and retrofitting high-performance production lines that demand deterministic timing and micron-level positioning.

Technical Configuration

The EVS9324-EKV004 "Servo Cam Profiler" (EK) variant is distinguished by its ability to store and execute complex motion curves internally. This functionality allows the drive to follow a master axis (via encoder signal or virtual master) and execute non-linear movements based on a predefined 2D path. The 3.0 kW power stage is optimized for rapid dynamic response, supporting high-resolution resolver or encoder feedback to maintain stability at high speeds. Its compact, narrow-width design (9.70 cm) facilitates high-density mounting in electrical cabinets, and its integration into the Lenze Global Drive Control (GDC) ecosystem ensures that engineers can visualize and tune cam profiles with millisecond precision.

Technical FAQs

What is the benefit of a "Cam Profiler" over a standard servo inverter?

A standard inverter follows a set speed or position. The EVS9324-EKV004 (EK) variant allows you to program a specific relationship between a master axis and the slave motor. This enables complex movements, like a knife that accelerates to match a moving web speed exactly during a cut and then resets, all without mechanical cams.

Is the EVS9324-EKV004 compatible with different feedback systems?

Yes. The 9300-series uses a modular feedback system. Depending on the installed plug-in module, it can support resolvers (standard for most Lenze motors), SinCos encoders, or TTL incremental encoders.

How do I transfer cam profiles to the drive?

Cam profiles are typically created in the "Lenze Cam Editor" within the GDC software suite. Once the mathematical curve is defined, it is downloaded as a data table into the drive’s non-volatile memory via the RS-232/485 or CAN interface.

Engineering & Installation Guide

• Synchronous Wiring: For master-slave configurations, ensure that the master encoder signal is distributed using shielded, low-capacitance cables. Any signal jitter in the master input will be amplified by the cam profiler, potentially causing mechanical vibration.

• Thermal Management: The 3.0 kW unit utilizes forced-air cooling. When mounting multiple EVS9324 units, maintain the side-by-side spacing recommended by Lenze to ensure the vertical airflow is not obstructed. Periodically check the internal fan status through the drive’s diagnostic parameters.

• Safety Considerations: Because cam profiles can involve rapid, non-linear accelerations, always verify the "Mechanical Limits" settings in the software. Ensure the peak torque required by the cam profile does not exceed the 3.0 kW rating or the motor's peak stall torque to avoid "Follow Error" (OC1) trips.
