PLC servo Lenze série 9300 EVS9327-EIV004 15,0 kW

Product Overview

The EVS9327-EIV004 (EVS9327EIV004) is a sophisticated 15.0 kW Servo PLC integrated into the high-performance Lenze 9300-Series. Unlike standard drives, this Servo PLC variant combines advanced motion control with programmable logic capabilities, allowing it to execute complex machine sequences independently of a centralized controller. In demanding industrial sectors such as plastics processing, material handling, and specialty paper conversion, the EVS9327-EIV004 provides the deterministic processing power required for high-speed synchronization and precision positioning. Although this model entered its phase-out period in 2017, its field-proven reliability makes it an essential component for engineers seeking to maintain legacy systems with high-torque requirements while ensuring minimal disruption to existing production workflows.

Technical Configuration

The EVS9327-EIV004 features a versatile hardware architecture designed for high-performance automation. The "EI" designation identifies it as a Servo PLC, which supports IEC 61131-3 compliant programming, enabling decentralized intelligence directly at the drive level. The "V004" suffix indicates a specific hardware revision, often incorporating optimized internal cooling paths or specialized firmware versions for broader compatibility. Housed in a compact IP20 enclosure, the unit manages a rated power of 15.0 kW with an integrated power stage that supports high-dynamic acceleration cycles. It typically features built-in system bus communication (CAN) and modular slots for expanded fieldbus connectivity, ensuring seamless data exchange within complex multi-axis architectures.

Technical FAQs

What is the primary benefit of using a Servo PLC like the EVS9327-EIV004 over a standard servo drive?

The integrated PLC functionality allows the drive to handle logic tasks and motion profiles internally. This reduces the processing load on the main machine PLC and minimizes network traffic, resulting in faster response times for localized sensor-to-motor loops.

Can the EVS9327-EIV004 be programmed using standard Lenze software?

Yes, this unit is typically programmed using the Lenze Drive PLC Developer Studio (DDS). It supports several languages under the IEC 61131-3 standard, including Ladder Diagram (LD) and Structured Text (ST), providing flexibility for diverse engineering requirements.

Is it possible to upgrade the communication interface of this phase-out model?

Yes, the 9300-Series supports various plug-in communication modules. Even though the drive is in a phase-out state, it remains compatible with Lenze’s range of AIF (Application Interface) modules for PROFIBUS, DeviceNet, or EtherCAT integration.

Engineering & Installation Guide

• Heat Dissipation and Airflow: With a 15.0 kW power rating, managing thermal output is vital. Ensure a minimum vertical clearance of 100 mm above and below the unit for unobstructed airflow. In enclosed cabinets, ensure the total heat loss of the drive (approx. 3-5% of rated power) is accounted for in the cabinet’s cooling calculations.

• Decentralized Logic Grounding: Since the EVS9327-EIV004 acts as a PLC, it is sensitive to electromagnetic noise on its I/O lines. Use twisted-pair, shielded cables for all digital and analog signals, and ensure the shield is bonded to a clean functional earth (FE) to prevent logic errors or unexpected motion triggers.

• Safety and Maintenance: Before performing any wiring changes or internal inspections, disconnect the mains supply and wait at least 10 minutes. The internal DC bus capacitors retain high voltage (up to 800 VDC) for several minutes after power-down. Always measure the DC+ and DC- terminals with a rated voltmeter to confirm they are below 50 VDC before proceeding.
