Product Overview

The EVS9328-EKV004 (EVS9328-EKV004) is a specialized servo cam profiler within the Lenze 9300-series, designed to provide high-precision motion synchronization for complex industrial tasks. Rated at 22.0 kW, this unit excels in applications such as electronic gearing, flying saws, and precision rotary indexing tables where mechanical cam reliability is required in a flexible, electronic format. Its robust architecture and specialized internal processing power enable it to maintain tight synchronization in high-speed manufacturing environments, effectively reducing mechanical wear and optimizing production throughput for industries ranging from packaging to metal processing.

Technical Configuration

This controller utilizes the 9300-series platform to execute sophisticated cam profiles with high temporal resolution. The device features integrated PID control loops and dedicated synchronization inputs, allowing it to track master axis position and velocity with minimal phase error. The hardware is housed in an IP20-rated enclosure, optimized for control cabinet mounting where it benefits from environmental protection. Connectivity is modular, supporting various communication interfaces that allow it to act as a slave in a larger motion control network, receiving setpoints from a master PLC while executing complex internal motion laws independently.

Technical Specifications

FAQs

What defines the 'Servo Cam Profiler' functionality in this model?

The EVS9328-EKV004 includes specific firmware and hardware resources to execute motion profiles as a function of an external master position, allowing for the emulation of mechanical cams with high flexibility and accuracy.

Can this drive be used in applications requiring safety-related stop functions?

This model is designed for process control. Safety-related stop functions should be handled by a dedicated safety PLC or external safety relay system connected to the drive's enable inputs to meet the required performance levels.

Is the EVS9328-EKV004 sensitive to supply voltage fluctuations?

Like most high-power servo drives, the unit is sensitive to significant input voltage drops. Ensure the DC bus remains stable under high-torque transient conditions to prevent potential 'Undervoltage' trips during peak profile acceleration.

How do I calibrate the cam profile synchronization?

Calibration involves defining the master-slave relationship via the parameter software. Once the encoder interface for the master axis is correctly scaled, the cam profile is mapped to the position master using standard Lenze engineering tools.

Installation Guidelines and Best Practices

• Encoder Wiring: Use double-shielded, twisted-pair cables for the master encoder signal input. The cable shield must be grounded at both the drive end and the encoder end to prevent common-mode noise from disrupting the position reference.

• Heat Dissipation: With a 22.0 kW rating, internal thermal management is paramount. Ensure the drive is installed with sufficient vertical clearance and that the cabinet's internal airflow is directed away from heat-sensitive components, as the unit generates substantial heat during continuous duty cycles.

• Commissioning: Prior to enabling high-speed profiles, perform a 'dry run' with the motor uncoupled from the load. This allows for verification of the cam profile direction, scaling, and synchronization logic without the risk of mechanical collision.
