Atlas Copco PF4000‑C‑HW Compact Controller with Profibus Card (8433710005)

The Atlas Copco PF4000‑C‑HW, part number 8433710005, is a compact tightening controller that combines high‑performance torque control with built‑in Profibus DP communication. This unit is designed for applications where space is at a premium but connectivity to a Profibus network is essential. It delivers the same precision as larger Power Focus controllers in a smaller footprint, making it ideal for retrofit projects and compact workstations.

Compact Design

Measuring just 220 x 160 x 90 mm, the PF4000‑C‑HW can be mounted on a DIN rail or directly on a machine frame. The housing is made of extruded aluminum with passive cooling fins, eliminating the need for internal fans. All connections are located on the front panel for easy access, including tool connectors, power, I/O, and Profibus interface.

Profibus Integration

The integrated Profibus DP card supports baud rates up to 12 Mbps and enables cyclic data exchange with a PLC. The controller can send real‑time torque, angle, and status values to the PLC, and receive setpoints and start commands. The Profibus address is configurable via DIP switches or software. The module is fully compliant with Profibus profile for tightening controllers.

Control Capabilities

This controller supports all standard tightening strategies: torque, angle, yield, and gradient. It also includes a special "soft start" mode to reduce initial impact on delicate joints. The controller can store up to 50 programs, each with up to 8 steps. A built‑in sequencer allows simple logic control (e.g., wait for input, set output) without external PLC for basic stations.

Programming and Diagnostics

Programming is done via the ToolsTalk PF software or through the Profibus interface using standard acyclic services. The controller has a web server for diagnostics and configuration via Ethernet (if optional module fitted). LED indicators on the front panel display power, run, fault, and Profibus communication status.

Data Logging

Internal memory stores 5,000 tightening cycles with full torque‑angle curves. Data can be retrieved via USB or Profibus (acyclic). The controller also supports barcode input for traceability.

Safety and Compliance

Safety features include motor overcurrent protection, overtemperature shutdown, and emergency stop input. The unit complies with EN 61000‑6‑2 (immunity) and EN 61000‑6‑4 (emission). It carries CE mark.

Applications

Ideal for automotive sub‑assembly lines, electronics manufacturing, and appliance assembly where Profibus is the plant standard. Its small size allows placement close to the tool, reducing cable lengths and improving signal integrity.

Maintenance

No routine maintenance required. Firmware updates are performed via USB. The controller has no internal batteries.

Benefits

The integrated Profibus card eliminates the need for external gateways, reducing cost and complexity. Its compact design saves cabinet space, and the robust construction ensures reliable operation in industrial environments.

Conclusion

The Atlas Copco PF4000‑C‑HW with Profibus card (8433710005) offers a space‑saving, high‑performance tightening solution with seamless network integration, making it an excellent choice for modern, connected production lines.
