Our servo drives are typically paired with our extensive line of Kollmorgen servo motors,

which provide the most popular feedback support on the market (including resolvers,

incremental encoders, BiSS, EnDat, Hiperface, sinusoidal encoders).

Our servo drives have continuous duty power outputs ranging from 300 watts to 50,000 watts.

With peak runtimes of a full 5 seconds in some drives, typically 3 times the rated continuous current,

many applications can use significantly smaller servo drives and extend the dynamic performance of the

servo drive family.

Connectivity is a key aspect of the machine, so we support many popular Ethernet fieldbuses such as

EtherCAT,EtherNet/IP, Profinet and SynqNet, and some models also support traditional fieldbuses

including Profibus,Devicenet, CanOpen, RS485, RS232 and Sercos II. Sercos II.

An upcoming technology to make machines safer is functionally integrated safety in servo drives.

The Kollmorgen S700 and AKD2G servo drives have integrated safety functions.

This enables machine builders to create inherently safer machines with flexible safety zones and less

wiring and configuration than ever before.

With the perfectly adapted AKD2G servo drive, the Kollmorgen 2G motion control system can fully

realize the full potential of our new generation servo motor, the AKM2G, and deliver unmatched power

density and control.

Features

The EtherCAT Coupler connects the real-time Ethernet system EtherCAT with modular, expandable

electronic terminal blocks.

A unit consists of a Bus Coupler, a set of terminals and a terminal.

The Bus Coupler recognizes the connected Bus Terminals and automatically assigns them to the EtherCAT

process image.

The Bus Coupler is connected to the network via the upper Ethernet interface.

The lower RJ 45 socket can be used to connect other EtherCAT devices in the same strand.

In an EtherCAT network, the EtherCAT Coupler can be installed anywhere in the

Ethernet signaling section (100BASE-TX) – except directly on the switch.

EtherCAT (Ethernet Control Automation Technology) is an Ethernet solution for industrial

automation characterized by excellent performance and particularly simple operation.

etherCAT enables Ethernet star topologies to be replaced by simple line structures.

In addition, EtherCAT can also be wired in the “classic” way using switches for the integration of additional

Ethernet devices.

The master does not require special plug-in cards and can be realized on any existing Ethernet controller

using very simple interfaces.

EtherCAT is therefore also ideally suited for small and medium-sized control applications and will open up

new fields of application for distributed I/O.

For EtherCAT, stand-alone I/O systems with protection class IP 20 are available as EtherCAT Terminals.

Unlike the Bus Terminals, in which the fieldbus signals are realized in a Bus Coupler

on a terminal bus that is internally independent of the fieldbus,

the EtherCAT protocol remains fully intact within the individual terminal.

The EtherCAT coupler supports the operation of all Bus Terminals.

As far as the user is concerned, the analog inputs/outputs are handled no differently than in the other series.

The information is processed as a byte array in the process image of the controller.

Analog and multifunction Bus Terminals can be adapted to each specific application.

Depending on the type, the registers of the analog Bus Terminals contain temperature ranges, gain values and linearization characteristics.

The Bus Terminals store settings permanently in a fail-safe manner.

In addition, the Bus Terminals can be optionally controlled via the control system.

With function blocks (FB), the programmable logic controller (PLC) handles the

configuration of the entire periphery during the startup phase.

If required, the controller can upload the configuration data created centrally in order to manage and store them centrally.

As a result, no new adjustments are required when changing bus terminals.

The controller automatically sets the required settings at power-up.

to provide flexibility. Single connectors/plugs (combined power and

feedback) are also available to minimize motor and cable cost (SFD and

Absolute Digital Encoders only).
