 Selecting the command interface in the Network operation mode (Pr.338,
Pr.339)
• Selecting a command interface is required for the following two types of commands: the operation command using the start
signals and the signals related to the inverter function selection, and the speed command using signals related to the
frequency setting.
• The following table shows the command interface for each function in the Network operation mode, determined by the
parameter settings: an external terminal or a communication interface (RS-485 terminals or communication option).
