Basic operation procedure (PU operation)
Setting the frequency with switches (multi-speed setting)
Use the operation panel (FR-DU08) (FWD or REV key) to give a start command.
Turn ON the RH, RM, or RL signal to give a frequency command (multi-speed setting).
Set Pr. 79 "Operation mode selection" = "4" (External/PU combination operation mode 2).
Operation example: Operate at a low-speed (10 Hz).
Turning ON the power of the inverter
The monitor display turns ON.
Changing the operation mode
Set "4" in Pr. 79. [PU] and [EXT] indicators turn ON. (For changing the setting value, refer to page 4-9.)
Setting the frequency
Turn ON the low-speed switch (RL).
