The new V41 firmware version for the K-Ducer KDU-1A controller introduces several new features designed to enhance configurability, boost connectivity, and simplify calibration with K-TESTER systems.
What’s new in Firmware V41?
- Advanced Total Angle Monitoring
The new firmware introduces dedicated parameters for simultaneous control of both total angle and angle from a predefined torque, allowing for more precise and flexible monitoring during operations. - KDU-1A ↔ K-TESTER Synchronization
With real-time data exchange and automatic program synchronization, torque calibration and verification become faster and more intuitive, improving overall operational efficiency. - Extended Connectivity
The KDU-1A now supports Modbus TCP, Open Protocol, and ToolsNet simultaneously, with multiple Open Protocol connections active at the same time — ideal for Industry 4.0 applications. - Simplified Barcode Management
The new PR/SEQ and SN+PR/SEQ modes allow users to load programs or sequences directly through barcode scanning, speeding up setup and reducing the risk of errors. - Continuous Usability Improvements
- Support for longer passcodes and a protected input screen
- CSV files enriched with torque and angle limits
- Simplified program management
- Updated K-TLS
A dedicated screw pickup position has been added, improving performance in automated applications. - Recommended K-TESTER Update
Even when used independently from the K-Ducer, the new K-TESTER firmware ensures full compatibility with KDU-1A V41, enabling real-time synchronization between the two systems.
Note: Make sure to update K-Expand to version 1.12 or later to ensure full compatibility with the V41 firmware.
Keeping your firmware up to date ensures maximum reliability, compatibility with new features, and smoother overall operation.
