System Overview

Product description

The DM2020 drive is a new generation of digital servo drives manufactured

by Moog-Casella for controlling brushless synchronous or asynchronous motors.

The drives have a multi-axis rack configuration with a power supply module

and various control modules positioned side by side.

• The power supply supplies direct current to the various modules via

connecting BUSBARs housed on the front connectors

• There are two standard power supply models

• Each module is available as a single- or dual-axis module

• The current ratings of the various axes range from 2 to 128 Arms of direct

current and 4 to 256 Arms of peak current

• Compatible feedback systems:

• Resolver

• Stegmann absolute single-turn sinusoidal encoder with and without hiperface

• Stegmann absolute multi-turn sinusoidal encoder with and without hiperface

• TTL incremental encoder

• Heidenhain absolute single-turn sinusoidal encoder with and without EnDAT

• Heidenhain absolute multi-turn sinusoidal encoder with and without EnDAT

• Heidenhain EnDat 22 full digital encoder

• Heidenhain linear encoder with EnDAT

• The modules are cooled by forced air, with fans incorporated in each module

• Ethernet interface on which the EtherCAT Real Time protocol is implemented

with the DS402 proile

• Standard CANOpen interface on which the CANOpen protocol is implemented

with the DS402 proile

• “Safe Torque Off” (STO) (protection against accidental start-up) incorporated

into each axis

• configuration/commissioning via GUI: Dx2020GUI allows users to conigure,

calibrate and control the drive

• Alarm diagnostics: Via GUI

• Accessories:

• EMC filters

• Power and signal cables

• Brake resistor

Integrated Safe Torque Off (STO) function

• The Safe Torque Off safety function is integrated as

standard in every drive.

Applications

• Single-axis applications in industrial automation

• Applications with high precision and top dynamics

installation

• Applications with personalised functions and flexible

configurations

• Applications requiring quick, precise movements

Features

• The extremely compact design allows machine builders to

reduce cabinet space and consistently cut layout installation

costs

• Maximum flexibility to work with different motor types,

different motor and load position tranducer and fieldbus to

meet all applications requirements

• Its user-friendly graphic interface (DX2020GUI) allows easy

access to all functions, simplifying the commissioning, the

machine start-up and system monitoring

• Metal Forming Machinery

• Injection and Blow-molding Machines

• Simulation

• Gas and Steam Turbines

• Packaging and Food Processing Machines

EXTREMELY COMPACT, SINGLE-AXIS, STAND-ALONE DRIVES FOR

HIGH ACCURACY AND FLEXIBILITY

The DS2020 is the single-axis, stand-alone, new servo drive,

specifically designed with extremely compact dimensions for

significant space saving.  Available in six sizes, from 2 to 192

Arms, continuous, and 4 to 384 A, peak, the DS2020 can be 

easily tailored to meet any application requirement with different

motor and load position tranducer and fieldbus interfaces.

SYSTEM OVERVIEW

Highly compact, modular design for top  productivity

• The DS2020 is a digital “stand-alone” servodrive,  purposely

designed with ultra compact  dimensions.  The current sizes

of the five versions (50. 75. 85. 125  165 and 355 mm) range

from 2 Arms to 192 Arms  continuous, and from 4 Arms to

384 Arms peak.

Designed to work with different motor types and

feedback devices

• The DS2020 servodrive is designed to control  synchronous

brushless or asynchronous motors (it is  compatible with

various feedback systems (Resolver  standard, encoder

single and multi-turn, incremental)  as well as motors with

sensorless algorithms.

User-friendly Graphic User Interface (GUI)

• The graphic user interface offers easy access to all  the drive

functions, simplifying the settings, initial  start-up and

system monitoring. Communication  with the PC is via a USB

or RS422 interface.

Moog’s line of actuation control solutions are designed to be used in

multiple aerospace and harsh environments.

The commercial actuation controllers fall into our Reconfigurable

Actuation Control Unit (RACU) product family. This family is capable

of covering a wide range of performance characteristics with varying

design parameters. This new product line is derived and based on

existing and qualified Moog heritage solutions that is specifically

focused on lower cost, faster lead times, and a reconfigurable nature.

The modularity and available of the controllers lends itself to both

rapid design iteration and solution evolution.

Key Features:

• Six Step and Field Oriented Control capable

• User configurable gains and filters allows for adjustment of system

behavior in application

• Configurable directly from MATLAB

• Qualified for launch vehicle environments

• Proven flight heritage

The Moog 2-channel Electronic Control Unit (ECU) is comprised of 2 Moog

hybrid stepper motor controllers, an EMI filter, and 6 analog pass-throughs

for telemetry. The ECU enclosure has been designed to allow 2 ECU’s to

be stacked to form a 4-channel ECU. The 2-channel ECU contains all power

conditioning, pulse sequencing and output driver stages necessary to drive

two 3-phase motors. The system electrical interface consists of power and

command input lines, output motor drive lines and telemetry outputs.

The required input commands are discrete for ENABLE and DIRECTION,

and a pulse train on the STEP input. An initial discrete logic state on the

ENABLE line will activate the control unit for the desired motor.

On the DIRECTION line, one logic state enables clockwise rotation, and the

other state enables counterclockwise rotation. Motion is initiated by the

application of a pulse train on the STEP command line.

Key Features:

• Based on Moog hybrid stepper motor controllers

• The ECU contains all power conditioning, pulse sequencing and output

driver stages necessary to drive two 3-phase motors.

• Input commands are discrete for ENABLE and DIRECTION, and a pulse

train on the STEP input.

• Small volume

• Low weight

• Provides Rad Hard operation
