Overview of the Lenze 8400 series

The Lenze 8400 series covers a wide range of drive applications, from standard machines to more dynamic processes. It emphasises platform consistency, modular accessories and software continuity for commissioning and diagnostics. The essential functions of an industrial frequency drive are present, with configurable acceleration and deceleration profiles, torque management to protect mechanical parts and the ability to optimise the energy efficiency of induction motors by precisely adjusting speed to process needs. The series' approach favours integration into control cabinets and communication with programmable logic controllers and numerical control systems so it can fit seamlessly into existing architectures. The hardware and software options available across the 8400 family allow connectivity and I/O to be adapted to the user's infrastructure while maintaining a consistent parameterisation logic across the series.

Industrial applications

The E84AVHCE3712SX0 is suited to drive applications where speed stability, repeatability and reduction of mechanical shocks are required:

• Conveying and intralogistics : belt speed control, section synchronisation, reduction of jolts at start and stop.
• Pumps and ventilation : fine flow adjustment to reduce energy consumption and preserve hydraulic or air-handling components.
• Packaging : control of web tension, consistent throughput rates, smooth format changeovers.
• Material handling and lifting : movement and indexing control, ramp handling to protect the load and the structure.
• Textile and paper : drives for winders and unwinders, improving process consistency by adjusting speed.
• Special machines : integration with PLC for complex sequences and dynamic setpoints.

Integration and communication

The drive integrates into new or existing architectures via the 8400 series platform. The communication modules available on the range enable data exchange with the machine's PLC and the supervision system, simplifying networking of drives with existing automation equipment. This integration facilitates diagnostics, status reporting and use of speed setpoints coming from the PLC or the numerical control on the line.

Commissioning is carried out progressively, with a parameter structure organised by function. Acceleration and deceleration ramps are configured to limit mechanical stress, and the built-in protections of the 8400 family contribute to the reliability of the motor-drive system. The exact values for input voltage, output voltage, rated power and control modes associated with the E84AVHCE3712SX0 depend on the reference configuration. For precise matching, it is recommended to check the drive's nameplate and the manufacturer's documentation for the 8400 series.
