Instruction Manual.
• When the terminal command LE ("Enable communications link via RS-485 or fieldbus") is
assigned to a digital input terminal, turning LE ON makes the settings of H30 and y98
enabled. When LE is OFF, those settings are disabled so that both frequency commands
and run commands specified from the inverter itself take control.
(Refer to the descriptions of E01 through E07, data = 24.)
No LE assignment is functionally equivalent to the LE being ON.
