ATLAS PF3107-G-DN-HW
ATLAS PF3107-G-DN-HW is an electric bolt torque drive unit (Nutrunner Drive Unit) belonging to the Tensor 3-7 Series of Atlas Copco. Classified as a “General” purpose model, it is specifically designed for industrial assembly environments that require high repeat positioning accuracy and multi-stage torque control. As the “Hardware Authorized (HW)” version, it enables full drive features through an internal hardware locking function, distinguishing itself from versions that require external dongles or software activation.
This drive unit is usually used with Atlas Copco’s Tensor S4/S7/S9 Series tools (such as ST, SR, SB), and is widely applied in the fields of automotive manufacturing, rail transit and precision equipment assembly.

Product Features
Multi-Mode Control
Supports independent torque or angle control, as well as composite control of both (e.g., tightening first then rotating), suitable for complex assembly processes.

High Safety and Error-Proof Design
- Thread Slip Detection: Automatically shuts down when thread damage or tool slippage occurs.
- Missing Tightening Protection: Triggers an alarm when missing bolt tightening is detected.
Data Traceability and Networking
Supports networking with PLC and MES systems via DeviceNet or Open Protocol, enabling real-time collection of torque data and process parameters to achieve traceability of the production process.
Hardware Authorized (HW) Version
Different from versions that require additional dongles or software activation, the G-DN-HW enables all functions directly through internal hardware, making installation and maintenance simpler.

Installation and Maintenance Recommendations
Installation
- Location: Usually installed on the guide rail or panel of a standard industrial control cabinet.
- Connection: Ensure the power supply (AC 100-240V) and communication lines (DeviceNet/Ethernet) are firmly connected.
Daily Maintenance
- Cleaning: Regularly remove dust and oil stains from the surface of the body to prevent overheating.
- Inspection: Regularly check if the connecting wires are loose and if the bolts have abnormal wear.
- Firmware Update: Update the firmware of the drive unit through official channels to obtain the latest functions and error fixes.
