Rockwell Automation 2098-DSD-xxx Ultra3000 Digital Servo Drives with DeviceNet - Manual (Page 12)

Publication 2098-RM001C-EN-P – August 2002
1-2 Overview
Installing, Connecting, &
Commissioning Ultra3000
Drives with DeviceNet This manual serves as a reference for configuring, monitoring, and
controlling Ultra3000 Drives with DeviceNet. Refer to the Ultra3000
Digital Servo Drive Installation Manual (2098-IN003x-EN-P) for
information regarding:
• configuring the rotary switches on the front panel of the drive
• wiring the DeviceNet connector
• understanding the DeviceNet LED indicators
• troubleshooting
Parameters and Electronic
Data Sheet The Ultra3000 Drive with DeviceNet contains a set of parameters that
are used to configure and monitor the drive. You can perform
configuration by changing the values associated with individual
parameters. Parameter values may be written and read via DeviceNet.
Writing a value to a parameter may configure drive operations such as
the acceleration or deceleration rates. Writing a value to a parameter
may also configure DeviceNet operations such as which input and
output assemblies are to be used for I/O communications with a
master (scanner). The parameter set is documented in Programming
Reference on page 2-1.
Electronic Data Sheet (EDS) files are specially formatted ASCII files
that provide all of the information necessary for a configuration tool
such as RSNetworx for DeviceNet to access and alter the parameters
of a device. The EDS file contains information on the number of
parameters in a device and how those parameters are grouped
together. Information about each parameter is contained in the file
such as parameter min, max, and default values, parameter data
format and scaling, and the parameter name and units. You can create
or access an EDS file stored in the Ultra3000 Drive with DeviceNet via
RSNetworx for DeviceNet (Version 3.00.00 Service Pack 1 or later) or
download an EDS file for the Ultra3000 Drive with DeviceNet from
Rockwell Automation - Allen-Bradley web-site www.ab.com/
networks/eds.
DeviceNet Messaging The Ultra3000 Drive with DeviceNet operates as a slave device on a
DeviceNet network. The drive supports Explicit Messages and Polled
or Change-of-State/Cyclic I/O Messages of the predefined master/
slave connection set. The drive also supports the Unconnected
Message Manager (UCMM) so that up to five Group 3 Explicit Message
connections may be established with the drive.
