The ARS 2100 servo positioning controllers (ARS servo 2nd generation) are intelligent AC servo inverters for operation direct from a single-phase mains supply. They are flexible and can be easily adapted to a number of different applications, with many adjustment and expansion options.
Due to the integrated Power Factor Correction the device already fulfils the standards according to EN 61000-3-2 (limitation of mains current harmonics). In addition to speed and torque control, positioning, speed and angle synchronisation with electronic gear, the CANopen protocol DSP402 allows the implementation of contouring controls with linear interpolation as well as time-synchronised multi-axis applications.
The ARS 2000 communicates with PLCs via Fieldbus like the integrated CAN Interface or Fieldbus options, e.g. Ethernet, PROFIBUS or SERCOS.
The servo positioning controllers can be used universally since they can be connected to various encoder systems and motor types.
With the menu-driven configuration tool Metronix ServoCommander (TM) and the automatic motor identification, the ARS 2000 quickly and comfortably adapts to your requirements.
