For details, refer to the RS-485 Communication User’s Manual, the Field Bus (Option) Instruction Manual or
Chapter 9.
• When the terminal command “LE” (“Select link operation (RS-485, BUS option)”) 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.
(Function codes E01 to E05, data = 24)
No “LE” assignment is functionally equivalent to the “LE” being ON.
