The Atlas Copco PF4000‑G‑HW, with part number 8433‑6100‑00 (also referenced as 8433610000), is a compact and powerful screwdriver controller from the Power Focus series. This unit is specifically designed for driving electric screwdrivers and nutrunners in light to medium‑duty assembly applications. It provides precise torque and angle control, ensuring consistent fastener tightness and joint quality. The PF4000‑G‑HW features a universal power supply, flexible I/O, and multiple communication options, making it suitable for a wide range of manual and automated workstations.
The unit is housed in a rugged metal chassis with a front‑mounted keypad and backlit LCD for local operation. It supports a variety of screwdriver types, including brush and brushless DC motors, with automatic tool recognition. The controller can store up to 64 tightening programs, each with independent torque and angle limits, allowing quick changeovers for different fasteners.
This controller offers torque control, angle control, and yield detection strategies. It also supports a "soft start" feature to reduce initial impact on delicate components. Multi‑step tightening (up to 5 stages) enables complex sequences such as pre‑positioning, final torque, and re‑tightening. The controller includes a real‑time clock for timestamping each cycle.

Using ToolsTalk PF software, engineers can create, edit, and download tightening programs. The software includes a graphical sequence editor and a trace viewer for analyzing torque‑angle curves. The controller’s display shows real‑time values and diagnostic messages; operators can adjust torque offset or set start‑up parameters on the fly.
Internal memory stores 5,000 tightening results with full curves. Data can be exported via USB or Ethernet. The controller supports OPC UA and Modbus TCP for SCADA integration. It also includes a web server for remote diagnostics.
Emergency stop input, motor overtemperature protection, and a hardware watchdog are standard. All I/O are isolated.
Ideal for electronics assembly, small appliance manufacturing, and automotive interior fastening. Used in both handheld and fixtured setups.
No internal batteries; firmware updates via USB. The unit is maintenance‑free under normal conditions.
Offers high accuracy and repeatability, reducing rework. Its compact size and flexible power input suit global deployment.
The Atlas Copco PF4000‑G‑HW screwdriver controller provides an efficient, reliable, and precise solution for small‑fastener assembly, backed by Atlas Copco’s quality and support.
