Metronix ARS 2108

The new ARS 2108 servo positioning controller extends the ARS 2100 product range to 1.5kW continuous. With a peak output of up to 6kW (0.5s) these servodrives are ideal for use with linear motors and other high dynamic applications requiring maximum acceleration and deceleration capabilities. The improved current, speed and position loop cycle times aid controlability further.

The drives 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 Fieldbus options, e.g. Ethernet, EtherCat, PROFIBUS or SERCOS (I and II).

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 ServoCommanderTM and the automatic motor identification, the ARS 2000 quickly and comfortably adapts to your requirements.

Universal encoder interface

The ARS family of drives can operate with rotary, linear and torque motors alike. Suitable feedback devices include, Resolver, Incremental Encoder (with/without commutation signals), Stegmann SinCos encoder (single-/ multiturn) with Hiperface, high resolution Heidenhain encoder as well as multiturn absolute encoder with EnDat 2.1 and 2.2 interface. SSI encoder interface is in prepartion.

Fieldbus options

RS232 (RS485) and CANopen (as per DSP 402) are standard interfaces on the ARS 2000 drives family. In addition the drives feature 2 extension slots, which can be populated with any of the following:

  • PROFIBUS-DP
  • Ethernet (TCP/IP)
  • Sercos (I&II)
  • EtherCat
  • DeviceNet
  • Additional digital I/O
