Metronix – ARS 2300 series

The ARS 2000 servo positioning controllers (ARS servo 2nd generation) are intelligent AC servo inverters for operation direct from a three-phase mains supply. They are flexible and can be easily adapted to a number of different applications, with many adjustment and expansion options.

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 options, for example EtherNET, EtherCAT, ProfiBUS, ProfiNET 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.
