Version 8.0
3.4.3
Technology module: PROFIBUS
Support of PROFIBUS communication as per DP-V0. For drive technology applications the functions
as per PROFIDRIVE Version 3.0 are available. The features include functions as per Application
Class 1 (speed and torque control) as well as per Application Class 3 (point-to-point positioning).
It is also possible to include the device into control systems via an I/O mapping via PROFIBUS. From
a control point of view, this option offers the same functionality as a conventional PLC coupling via
parallel wiring with the device’s digital I/Os.
Via a special Metronix telegram it is also possible to access all device-specific functions, exceeding
the functionality defined by PROFIDRIVE.
The Metronix PROFIBUS-profile of the previous ARS series is no longer supported by
the ARS 2300 series.
3.4.4
Technology module: sercos II
The sercos II interface is a slave fieldbus module that enables the use of the ARS 2000 servo drives in
numerically-controlled, highly dynamic drive applications, for example in machine tools. The sercos II
interface enables the position, speed, or torque control in accordance with the functionality of the
compliance classes A and B.
The connected module is automatically identified. Since the data exchange between the CNC system
and the servo drive is realised via optical fibre cables, mutual interference can be avoided. The drive
address is set, and the bus is activated, via the Metronix ServoCommander™ parameterisation tool.
The transmission rate can be set to a value between 2 and 16 Mbit/s.
3.4.5
Technology module: EtherCAT
The EtherCAT interface enables the connection of the ARS 2000 servo drive to the EtherCAT fieldbus
system. The communication via the EtherCAT interface (IEEE-802.3u) is realised with the aid of
EtherCAT standard cabling. It is possible between an ARS 2300 (firmware version 3.5.0.1.8 or higher)
and the Metronix ServoCommander™ parameterisation software (version 2.8.0.2.1 or higher).
3.4.6
I/O functions and device control
Ten digital inputs provide the elementary control functions (see
chapter 4.8.3 I/O interface [X1],
page 52
):
The ARS 2300 comprises a target table, in which the positioning targets are stored and from which
they can later be retrieved. At least four digital inputs serve the purpose of target selection; one input
is used as a start input.
The limit switches serve the safety limitation of the motion space. During a homing one of the two limit
switches may serve as a reference point for the positioning control.
