The Ferrocontrol DARC2 A04-15-26 with DE-SIR for Elumatec is the digital axis controller of the 4 A power class (2 kW) from the Ferrocontrol DARC 2 system, version with safety relay insert DE-SIR. This version is parameterised for machines made by Elumatec. The controller drives a brushless servo motor and is fed with the DC link voltage by the DARC supply module.

Function within the DARC 2 system
The axis controller converts the DC link voltage supplied by the supply module (560 V DC) into the three-phase motor voltage for the synchronous servo motor and controls the speed and position of the axis. Up to eight axis controllers operate on one supply module and communicate via the DARC system bus. The high-resolution encoder input (1 Vpp) is used for electronic commutation as well as speed and position feedback; absolute encoder systems can be operated on the same interface. A short-circuit-proof 28 V output switches the motor holding brake, and a PTC input monitors the motor temperature.

Safety relay insert DE-SIR
The controller is supplied with the safety relay insert DE-SIR fitted. Its relay contacts allow the axis to be secured against unintended start-up without switching off the mains voltage; the 7-segment status display is also provided.

For machine operators
If your window or profile machining centre reports a fault on an axis controller, you will find the type designation on the nameplate of the module. Tell us this designation and the machine type – Finke Maschinen supplies the matching replacement unit with the firmware and parameter sets belonging to your machine (Plug and Work). You swap the module without having to program or adjust anything yourself.
