3.2 Configuration
This section is intended to facilitate the configuration of the FR-E500KND inverter with
minimum effort. The description assumes that each value is the factory setting value. If
the user wishes to change these values, the data necessary to do so is provided later
in the manual.
This section also assumes that the network cabling is complete and DeviceNet
communication has been established. The LED status of the inverter must be blinking
green or steady green as described on page 25.
3.2.1 General description
The inverter is regarded as a slave device in the DeviceNet Communication Standard.
This means that the inverter cannot start a message on the network. A master device
must establish a connection to the inverter unit and then send commands, requests for
information, etc. (Note)
Note: When the master station is set-up and turned on, the inverter unit may need up
to 1 minute to get set to a ready for communication status.
This is a situation may occur for just the DeviceNet configuration stage, so this
should not be a general problem.
The FR-E500KND supports group 3 messaging as defined in the DeviceNet Standard.
This feature means that one master can control the inverter while another master is
able to read data from the same inverter. This also means that the DeviceNet master
must support the UCMM protocol for proper operation.
Note: It is strongly recommended that the user configures the DeviceNet network
using a software tool designed specifically for that purpose. The use of such a
tool greatly simplifies the configuration, reduces confusion, and enhances
accuracy. Additionally, the configuration tool will facilitate the elimination of
conflicts between network devices and ensure consistency throughout the
network.
One such tool is DeviceNet Manager™ as supplied by Rockwell Automation. Tools are
available from many other suppliers but the descriptions contained in the Getting
Started section are based upon the use of DeviceNet Manager™.
To use the DeviceNet Manager™ software, you will need to acquire the DeviceNet
Electronic Data Sheet (EDS) file. The EDS file is a standard DeviceNet file which
defines the configurable parameters of a field device and facilitates the network
configuration software’s ability to recognize a specific field device. Please refer to the
configuration software tool instruction manual for more information about the
installation and use of EDS files.
The most recent revision of the FR-E500KND EDS file is available on the Internet as
well as a separate item from Mitsubishi Electric.
Refer to page 180 for details on how to get this file.
