(a) Install the inverter.
(b) Perform wiring for the power supply and the motor.
(c) Select the control method (V/F control, Advanced magnetic flux vector control, or PM motor control).
(d) Input the start command via communication.
(e) The PU gives both start and frequency commands. (PU operation mode)
(f) The PU gives a start command, and inputs to terminal RH, RM, and RL give a frequency command.
(External/PU combined operation mode 2)
(g) The PU gives a start command, and voltage input to terminal 2 gives a frequency command. (External/PU
combined operation mode 2)
(h) The PU gives a start command, and current input to terminal 4 gives a frequency command. (External/PU
combined operation mode 2)
(i) Inputs to terminal STF and STR give a start command, and the PU gives a frequency command. (External/
PU combined operation mode 1)
(j) Inputs to terminal STF and STR give a start command, and inputs to terminal RH, RM, and RL give a
frequency command. (External operation mode)
(k) Inputs to terminal STF and STR give a start command, and voltage input to terminal 2 gives a frequency
command. (External operation mode)
(l) Inputs to terminal STF and STR give a start command, and current input to terminal 4 gives a frequency
command. (External operation mode)
