Selection of operation mode and
operation location
(5) Selection of control source in network operation mode (Pr. 338, Pr. 339)
⋅ As control sources, there are the operation command sources that control the signals related to the inverter start
command and function selection and the speed command source that controls the signals related to frequency setting.
⋅ In network operation mode, the commands from the external terminals and communication (RS-485 terminals or
communication option) are as listed below.
[Explanation of table]
External : Operation is valid only from external terminal signal.
NET : Control only from communication is valid
Combined : Operation is valid from either of external terminal and communication.
: Operation is invalid from either of external terminal and communication.
Compensation : Control by signal from external terminal is only valid when Pr. 28 Multi-speed input compensation selection = "1"
