The AFC3000 is a high-speed servo tightening system (nutrunner) with a torque range of 0.2–5000 N·m (depending on model). Patented thread-engagement overshoot suppression is available as an option, preventing overshoot even when engaging threads at more than 1,000 rpm. Controllers are the MFC-S series (MFC-S008, MFC-S024, MFC-S060, MFC-S120), selected according to the tool model used; up to 32 spindles can be linked through the spindle link port, and up to 120,000 tightening results and 100 torque curves can be stored. Expansion units add fieldbus support for CC-Link, DeviceNet, PROFIBUS, PROFINET, EtherNet/IP, CC-Link IE and EtherCAT, or a CompactFlash memory card and server connection module.

Typical Applications
Automatic machines with multi-spindle synchronized tightening
Up to 32 spindles can be linked through the spindle link port, with controllers exchanging quality data over high-speed communication — suited to automatic machines that tighten multiple screws simultaneously or in sequence.
Time-saving high-speed thread engagement
With the optional thread-engagement overshoot suppression, there is no overshoot even when engaging threads from speeds above 1,000 rpm, shortening the time needed per screw.
Stations with limited space or access angle
Tool types include straight, offset and angle; offset and angle head tools reach tightening positions where adjacent parts interfere or the access angle is limited.
Lines that require fieldbus integration
Expansion units add support for CC-Link, DeviceNet, PROFIBUS, PROFINET, EtherNet/IP, CC-Link IE and EtherCAT, and quality data can be saved to a CompactFlash memory card.
Frequently Asked Questions
What torque range and tool types does the AFC3000 cover?
The supported torque range is 0.2~5000 N·m, depending on the selected model. Tool types include straight, offset and angle tools, available for pairing or as options. Tool models correspond to the controller model used: MFC-S008 corresponds to MFT-***M10; MFC-S024 to CFT-***RS1 and NFT-***RM1/RM2; MFC-S060 to CFT-***RS3 and NFT-***RM3; MFC-S120 to CFT-***RM4J, NFT-***RM4H and NFT-***RM5. For the maximum torque, speed and dimensions of each model, please refer to the catalog or contact our sales team.
Will the AFC3000 overshoot when engaging threads at high speed?
Thread engagement overshoot suppression is an optional feature; with it, no overshoot occurs even when engaging threads at speeds above 1,000 rpm. This is a patented technology. A high-speed shock absorber is also available as an option to protect the mechanism and motion system. If your process requires high-speed thread engagement, please specify it when selecting the model.
How many spindles can AFC3000 controllers link, and how much data can they store?
All MFC-S series controllers have a Spindle Link Communication Port that can connect up to 32 spindles. Through high-speed communication between controllers, quality data is processed 3 times faster than on previous models, reducing the control load on the host computer. Tightening result memory holds up to 120,000 results, plus the last 500 results for rejected parts; torque curve memory holds the last 100 curves and the last 100 curves for rejected parts. All four controllers have the same memory specifications.
Which communication interfaces does the AFC3000 support? Is data lost when no PC is connected?
The controller itself has an Ethernet PC communication port compliant with IEEE802.3 (100BASE-T), 1 RS232C port (38400bps default, with 19200/9600bps also available), and standard I/O with 12 inputs and 12 outputs. For more interfaces, add expansion units: Option1 choices are MFC-DT (32 expansion digital inputs and 32 outputs), MFC-CC (CC-Link V2), MFC-DN (DeviceNet), MFC-PB (PROFIBUS), MFC-EN (EtherNet/IP), MFC-PN (PROFINET IO), MFC-CI (CC-Link IE) or MFC-EC (EtherCAT); Option2 choices are MFC-CF (supports CompactFlash memory cards and adds 2 RS232C ports) or MFC-CFEN (adds Ethernet for connection to a server PC and 1 RS232C port). Large amounts of data, including quality data, can be stored on the memory card even when no PC is connected. An MFC-DP01 display unit is also available.
What are the power and environmental requirements of the AFC3000 controllers?
They vary by controller model. The MFC-S008 uses single-phase AC100V~230V ±10%, while the other three use three-phase AC200~230V ±10%, 50/60Hz. Control power is DC24V ±10%: 0.5A for the MFC-S008/S024/S060 and 1A for the MFC-S120. Instantaneous maximum peak current ranges from 5.6 Arms on the MFC-S008 to 84.8 Arms on the MFC-S120, continuous AC drive current is 1.1~5.2 Arms, and transformer capacity is 0.3~4.0 KVA × number of spindles. The operating environment is the same for all four: 0~+50°C, humidity 90%RH or less.
How is the AFC3000 different from an ordinary electric screwdriver? Is it a servo screwdriver?
Yes. The AFC3000 is a servo-motor-driven tightening system, also called a servo screwdriver or nutrunner. Ordinary electric screwdrivers usually rely on a mechanical clutch that slips at the set torque, so accuracy drifts as the clutch wears and no record of each screw is kept. The AFC3000 controller monitors torque and angle in real time, judges each result as OK/NG, stores up to 120,000 tightening results and 100 torque curves, and uploads data to MES over fieldbus, making it suited to automatic screw tightening machines and lines that require quality traceability.
