The Lenord+Bauer GEL 8400 MotionController is a compact, high-performance 6-axis controller specifically designed for the demanding conditions of wind turbine rotor hubs. It meets all requirements for both onshore and offshore installations worldwide, and is available in Hot Climate (HCV) and Cold Climate (CCV) versions.

Key Features

• Rugged Design: Extended temperature range from -40°C to +70°C, resistant to shock and vibration, front panel IP67 protection.
• High I/O Density: 30 digital inputs, 15 digital outputs, 3 analog inputs, 3 analog outputs, 4 PT100 inputs, 6 SSI inputs, and 6 incremental inputs.
• Multiple Interfaces: 2x CANopen onboard, 2 serial interfaces (RS232, RS422/485), and an optional EtherNet/IP or PROFIBUS-DP module.
• Remote Service Web: Built-in web server for condition monitoring, parameter read/write, fault logging, and remote firmware updates via FTP/HTTP.
• Integrated HMI: CPU, LCD display (64x240 pixels), and keyboard are integrated into a single compact unit for direct on-site operation.

Applications

The GEL 8400 is primarily designed for wind power (onshore, nearshore, offshore), tidal power plants, and other robust industrial environments requiring precise multi-axis motion control in harsh conditions.

Remote Service & Connectivity

The built-in web server enables comprehensive remote service capabilities: condition monitoring of actual values, reading/writing parameters, reading stored faults, LB-Graph interface, remote firmware updates, and a remote service logbook.
