PARAMETERS
(5) Selection of command source in Network operation mode (Pr. 338, Pr. 339)
⋅ There are two control sources: operation command source, which controls the signals related to the inverter start
command and function selection, and speed command source, which controls 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 : Command only from control terminal signal is valid.
NET : Command only from communication is valid
Combined : Command from either of external terminal and communication is valid.
⎯ : Command from either of external terminal and communication is invalid.
Compensation : Command by signal from external terminal is only valid when Pr. 28 Multi-speed input compensation selection = "1"
