Atlas Copco Power Focus 8 Family Selection Configuration and Virtual Station Function Complete Explanation

Atlas Copco Power Focus 8 Family Selection Configuration and Virtual Station Function Complete Explanation

In the process of moving towards smart factories, digitalization and flexibility of assembly lines have become core demands. The Power Focus 8 (PF8) family launched by Atlas Copco, as a new generation of tightening control platform, takes the concept of Virtual Station as the core, cooperates with powerful hardware ecology and software functions, and provides accurate matching capability levels for tightening applications of different complexity. This article combines the official product manual to systematically sort out the hardware composition, virtual station level classification, functional expansion options, multi axis application configuration, and service ecology of the PF8 family from the perspective of engineering selection, helping engineers quickly build intelligent assembly solutions suitable for their own production lines.

PF8 Family Hardware Overview: Controllers, Drivers, and Intelligent Modules

The Power Focus 8 family includes three major hardware cores:

Power Focus 8 Controller: A universal main controller that supports connecting up to 20 tools (including battery tools, wired tools, and fixed tools), compatible with 15 tool families, providing Wi Fi expansion and lower infrastructure costs, a unified and optimized user interface, and seamless integration with software ecosystems.

Power Focus S drive unit: independent drive, can be used as a secondary controller for PF8, especially suitable for fixed and multi axis applications. Provide standard (1-phase) and high-voltage (3-phase) versions, with energy consumption 50% lower than the controller, and equipped with LED status indicators for easy maintenance and troubleshooting.

Intelligent Application Module (IAM): A pluggable storage unit that includes dual partition dedicated memory for upgrading, backup, and recovery. All software, tightened data, and configurations are stored centrally for quick backup and version switching.

In addition, PF8 also offers a high voltage version (HV), supporting 3-phase 380-480V power supply, fully compatible with the electrical framework of the original PowerMACs 4000 fixed controller, and supporting all models of the QST series (from QST34 to QST210), achieving seamless transition for fixed applications.

Virtual Station - Decider of Function Level

The virtual station is the core software authorization unit of the PF8 platform, which determines the types of tools, functional scope, protocol support, and data reporting capabilities supported by the controller. Different levels correspond to different application scenarios, and users can choose virtual sites with electronic or physical delivery (1/2/5/10 sets) as needed.

2.1 Batch Control - Customer Critical Type

Applicable scenarios: Tightening variants are limited, but torque control tools are needed to replace pneumatic tools.

Core competencies: Support torque control and angle monitoring, support electric battery pulse tool (TBP-S). Includes batch counting function to ensure correct tightening times.

Parameters: 1 program, 1 sequence, 4 identifiers, clutch step only.

Value: More precise than pneumatic tools, achieving basic OK/NOK traceability.

2.2 Joint Control - Quality Critical Type

Applicable scenarios: There are many variants of the site, and it is expected to replace multiple pneumatic tools with one electric tool.

Core competency: Support torque control tightening and improve accuracy; Support angle monitoring.

Parameters: 16 programs, 16 sequences, 4 identifiers.

Value: Reduce the number of tools and improve assembly flexibility.

2.3 Station Control - Quality Critical Type

Applicable scenarios: Applications that require torque control and angle control, but have simpler programming options.

Core capability: Support the connection of cut-off tools (BCV/P-Re) and click wrench (MWR-S) to PF8, and batch counting to ensure the correct quantity.

Parameters: 1 program, 1 sequence, 4 identifiers, clutch step only.

Value: Provide basic process control for the replacement of pneumatic tools.

2.4 Critical Control - Safety Critical Type

Applicable scenarios: Tightening applications that require full traceability must have the results stored and reported to external systems.

Core competencies: Support torque control, angle control, advanced tightening strategies (such as TrueAngle, low reaction force strategy).

Parameters: 250 programs, 250 sequences, 4 identifiers, supporting up to 4 VIN number associated results.

Value: Suitable for tightening safety critical components and meeting the strictest traceability requirements.

2.5 Process Control - Safety Critical (Highest Level)

Applicable scenarios: Extremely demanding tightening applications that require advanced tightening strategies and full traceability.

Core competency: Add more complex strategy options on top of Critical, including TrueAngle and low response strategies by default.

Parameters: 250 programs/sequences, 4 identifiers, torque/angle control, advanced strategy.

Value: Meet high demand scenarios such as aerospace and automotive chassis.

2.6 Sync Critical Control&Sync Process Control

Specially designed for multi axis synchronous tightening, supporting up to 50 tools to work simultaneously at one workstation, including Reject Management, suitable for multi axis synchronous safety critical applications.

Function extension - "add" capabilities for specific applications

On the basis of virtual stations, capabilities can be further enhanced by adding features, which can be delivered electronically (within 24 hours) or physically.

Function Name Applicable Tool Core Value

Low Reaction Strategies: STR and SRB tools use TurboTight/TensorPulse to significantly eliminate reaction forces, improve ergonomics, and reduce operator fatigue

TrueAngle only eliminates the influence of the operator on the tightening angle using the STR tool, improving the accuracy of angle control

Yield Control controls the torque drop in the plastic zone to ensure high clamping force and allows for the use of smaller screws

Open Protocol Extension supports the transmission of tightening curve data through open protocols, allowing external systems to modify and upload tightening programs

Industrial Location Guidance is an integrated error prevention system that tracks the precise position of tools relative to the fastening position, ensuring correct sequence and position

Zero Position: Set a fixed starting position arbitrarily to ensure that each tightening starts from the same angle and improves consistency

Automation Rules: Controller level controller signals can be flexibly combined and configured with external devices such as stacking lights and torque arms to simplify integration

These features can be used in combination, such as Critical Control+TrueAngle+Low Reaction, providing a complete solution for high-end STR tools.

Tool compatibility matrix and multi axis applications

PF8 supports 15 tool families, ranging from clutch tools, electromechanical wrenches, low reaction force tools to advanced sensor tools. The specific compatibility is as follows:

Controller model voltage compatibility tool

PF8/PF8 S (1 phase) 100-120/200-240V Tensor SL, Tensor ES/ST/STR/SR, QST<350Nm (≥ 200V required)

PF8 HV/PF8 S HV (3-phase) 380-480V All QST tools (QST34~QST210) fully support PowerMACs 4000 migration

In multi axis applications, the main switch box (MSB) provides unified power supply for the controller and driver, supports daisy chain expansion, and one PF8 can connect up to 20 tools, while the Sync virtual station supports up to 50 tools to be synchronously tightened at one workstation.

Software and Management Tools: ToolsTalk 2 and IAM

ToolsTalk 2: Configuration management solution covering all controllers on the production line, providing complete traceability and visibility.

IAM (Intelligent Application Module): Dual partition design, supports retaining old versions during online upgrades, and can quickly roll back in case of failures to ensure uninterrupted production lines.
