sensorless vector control).
(d) Input the start command via communication.
(e) The PU gives both start and frequency commands. (PU operation mode)
The PU gives a start command, and inputs to terminal RH, RM, and RL give a frequency command.
(f)
(External/PU combined operation mode 2)
The PU gives a start command, and voltage input to terminal 2 gives a frequency command.
(g)
(External/PU combined operation mode 2)
The PU gives a start command, and current input to terminal 4 gives a frequency command.
(h)
(External/PU combined operation mode 2)
Inputs to terminal STF and STR give a start command, and the PU gives a frequency command.
(i)
(External/PU combined operation mode 1)
Inputs to terminal STF and STR give a start command, and inputs to terminal RH, RM, and RL give a
