When adding the FR-E5ND DeviceNet Option Unit to a FR-E520S-EC/CH or FR-E540 (all versions) series inverters that
have previously been configured for a specific application, it may be necessary to complete a "Parameter All Clear" (PrClr)
instruction in the inverter in order to remove unintentional conflicts and to allow the inverter to recognize the presence of the
If this becomes necessary, you will need to record the existing configuration before issuing the PrClr command as this
command will restore factory default values to all inverter parameters. Once the command is completed and the inverter has
recognized the FR-E5ND option unit, the inverter configuration data may be re-entered either via the parameter unit or the
To use the DeviceNetManager™ 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 softwares 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.
Refer to Appendix 1 for details on this file.
3.2 Basic Configuration
3.2.1 Setting the Baud Rate:
The baud rate must be consistent throughout the network in order to establish communication and allow configuration via the
network. Therefore, this step is critical to the success of the FR-E5ND option units configuration.
Upon power-up, the FR-E5ND DeviceNet option unit will default to a communication speed of 125 Kbps.
The baud rate may be set via the network using "Baud Rate", attribute 2 of DeviceNet Class 0x03, instance 1. See section
6.2.3 for further information.
