Function Controller fc20

Process reliability

  • highest process reliability
  • controls itself up to 100%
  • counts screwdriving cycles & supervises assembly times
  • only shuts-off when the preset torque is reached
  • recognizes change of parts
  • allows the connection of up to 3 different screwdrivers
  • design selection of the screwdrivers according to application (inline, pistolgrip, angle-head)
  • individual screw-process configuration through free programmability
  • integrated torque measuring function, diagnostics and evaluation
  • comprehensive documentation possibility
  • highest operator friendliness through graphical touch screen

This controller can also manage up to three different screwdriver model connections of the series MICROMAT-F and MINIMAT-F.

The function control fc20 distinguishes itself through an exceedingly high process reliability, individual screw-process configuration by the free programmability, integrated torque measuring function, extensive diagnostics- and analysis possibilities, as well as comprehensive documentation possibility and comfortable operator guidance.

Highest process reliability: controls itself up to 100%

The quality criteria connected with the screwdriving process are automatically supervised and analyzed. In case of a faulty screw assembly cycle, for example due to mishandling of the screwdriver, faulty assembly materials or an interrupted screw assembly cycle, the failure can be reset by the operator or if preferred by a qualified specialist when utilizing the available password protection function. The positive shut-off function of the clutch is monitored via an internal sensor also the minimum/maximum screw assembly time per screw and the number of good screw joints per production part are compared to the preset values in the controller. Only the positive feedback of all individual signals allows a change of the part – 100% Process Reliability.

Individual screw-process configuration through free programmability

With its convincing variety, the fc20 decidedly sets an exclamation mark: For maximal 7 sequences each sequence consisting of up to 99 programs, any screwdriving process can be individually generated.

The new fc20 contains freely usable power outputs. So, it is easy to integrate a part-lock feature into the assembly process. The Operator can also program additional processing steps by himself.
The new function control recognizes up to three part sensors and so guarantees a reliable presence- and positioning control of even multi-level parts.

Torque measuring functions, comprehensive diagnostics- and evaluation possibilities

Comprehensive diagnostics possibilities round-off the wide application spectrum of the screwdriving control fc20. By the use of an optional external rotary transducer, the Operator is able to control the – on the Screwdriver preset torque, directly on the part to be assembled, which is a big relief for maintenance and quality management. The integrated diagnostics functions are capable to test every in- and output of the control and additionally displays their operating status. An internal voltage control assures the continued functional safety of the fc20.

Comprehensive documentation possibility

For each products, the assemblies that took place are clearly assigned. An optional connected barcode-reader reads the barcode on any part to be assembled and then stores the final-values for each individual assembly together with this barcode. These final-values are stored for seven days and can be transmitted for the traceability of the production over the integrated serial port to a PC. That way, each program step is statistically retained. The number of good- and bad assemblies, as well as the average assembly time allow the control and optimization of the assembly process. The communication with a host controller (PLC or industrial PC) is possible through the integrated 24V I/O-port. The fc20 offers five power outputs.

Highest operator friendliness through graphical touch screen

An integrated graphical touch screen with a clear structure and a color-coded difference of the results, lead the operator intuitively to the desired submenus. The submenus allow the simple selection of assembly-sequences, programs and diagnostic functions.
