Lenze 2008 Function Board – 2000 Series Voltage Follower Module
Het item werd toegevoegd aan uw offerteaanvraag
Product Information
The Lenze 2008 Function Board is a dedicated voltage follower and analog signal conditioning module engineered for Lenze 2000 Series modular drive control systems. Operating within host controller sub-rack chassis and motherboard assemblies, this electronic board buffers incoming analog reference signals to prevent signal degradation, eliminate ground loops, and isolate sensitive drive electronics. It provides setpoint stability in industrial applications such as converting and web processing, packaging machinery, material handling systems, and textile manufacturing, where master-slave drive speed synchronization and multi-axis speed ratio matching are required.
Connecting via a direct edge card interface and terminal pin header, the Lenze 2008 fits directly into standard 2000 Series sub-rack slots. Commissioning a replacement unit is entirely hardware-driven, eliminating the need for external programming tools or software interfaces. Onboard precision trim potentiometers and configurable jumper positions allow control technicians to manually set zero-point offset and adjust signal gain directly on the module. When putting a spare into service, matching the gain and offset potentiometer settings of the original board ensures proper signal scaling and seamless integration with existing drive control loops. ABC Industrial Parts supports maintenance teams with tested replacement modules to assist in restoring operational performance.
Because the Lenze 2008 is a hardware-based analog signal conditioner, field verification relies on measuring incoming analog setpoint voltages, inspecting connector seating on the edge card, and monitoring board output response across the operational speed range. Physical inspection of board contacts and multi-axis speed matching behavior helps identify signal scaling discrepancies or drift in the control loop. When internal electronic component failure occurs or potentiometer calibration no longer yields stable setpoint conditioning, field repair of the circuit board is typically unfeasible. Sourcing a fully tested replacement module from ABC Industrial Parts provides a direct route back to reliable production without modifying the broader 2000 Series control architecture.

Programming and Configuration
The Lenze 2008 Function Board utilizes hardware-based configuration, eliminating the need for programming software, digital communication cables, or external setup tools. Operational calibration is performed directly on the circuit board through precision trim potentiometers and configurable hardware jumpers.
During initial setup or module replacement, technicians adjust the onboard potentiometers to calibrate zero-point offset and control signal gain. Replicating the physical jumper settings and trim positions from the original unit ensures exact setpoint scaling, enabling accurate matching of analog voltage signals across master and slave drive configurations.
Communication and System Integration
System integration for the Lenze 2008 is accomplished via a direct edge card connector and terminal pin header designed to mate with standard Lenze 2000 Series sub-rack chassis and motherboard assemblies. This physical interface delivers analog reference signals directly to the drive control bus.
Within multi-drive architectures, the module acts as a high-integrity signal buffer. By conditioning incoming analog voltages, it prevents signal degradation over extended cable runs, removes potential ground loops, and protects core drive electronics during multi-axis speed synchronization.
Replacement and Spare Part Considerations
As the Lenze 2008 module is officially discontinued by the manufacturer, maintaining functioning spares is essential for facility operations that rely on legacy Lenze 2000 Series drive systems. Replacing an existing unit requires matching physical slot dimensions and ensuring clean contact seating on the sub-rack motherboard.
Prior to putting a replacement module into full operation, technicians must perform a manual trim potentiometer calibration under actual signal conditions. Verifying gain scaling and zero-offset response against reference setpoint values prevents speed tracking errors in synchronized multi-motor drives.
