REMARKS
Multi-speed setting using parameters is available even during PU operation.
Pr. 24 to Pr. 27 settings have no priority among them.
When Pr. 59 Remote function selection ≠ "0", multi-speed setting is invalid as RH, RM and RL signals are remote setting signals.

Multi-speed setting for 4 or more speeds (Pr. 24 to Pr. 27)
Frequency from speed 4 to speed 7 can be set according to the
combination of the RH, RM and RL signals. Set the running frequencies
in Pr. 24 to Pr. 27 (In the initial value setting, speed 4 to speed 7 are
invalid).
