Basic operation
NOTES Terminal RH is initially set to 60 Hz for the FM type inverter, and to 50 Hz for the CA type inverter.
Terminal RM is set to 30 Hz, and terminal RL is set to 10 Hz. (To change the frequencies, set Pr. 4,
Pr. 5, and Pr. 6.)
In the initial setting, when two or more of multi-speed settings are simultaneously selected, prior-
ity is given to the set frequency of the lower signal.
For example, when RH and RM signals turn ON, RM signal (Pr. 5) has a higher priority.
Up to 15-speed operation can be performed.
