Communication setting
Set communication parameters.
Be sure to match the settings to those made under [Communication Setting] of the editor.
(Underlined setting: default)
*1 Available when the communication is enabled by digital input.
Example: To make the communication enabled when digital input terminal X1 is turned ON;
Set “24 (link operation)” for function code E01 and turn on the digital input terminal X1 externally.
Terminals from X2 to X9 can also be used. Set the function code corresponding to the digital input terminal to use.
*2 When “FRENIC5000G11S/P11S (MODBUS RTU)” is selected for model selection on the editor, select “Modbus RTU” for the
communication protocol on the inverter.
*3 The communication parameter (data length) is fixed to 8 bits.
Available Device Memory
The available setting range of device memory varies depending on the model. Be sure to set within the range available for the
model to be used. Use [TYPE] when assigning indirect device memory for macro programs.
