5.1.3 Setting the frequency by switches (three-speed setting) (Pr. 4 to Pr. 6)
POINT
 Use the operation panel (
 Switch ON the RH, RM, or RL signal to give a frequency command.
 Set "4" (External/PU combined operation mode 2) in Pr. 79 Operation mode selection.

REMARKS
 The initial values of the terminals RH, RM, RL are 60Hz, 30Hz, and 10Hz. (Use Pr. 4, Pr. 5 and Pr. 6 to change.)
 In the initial setting, when two or three of multi-speed settings are simultaneously selected, priority is given to the set frequency
of the lower signal.
For example, when the RH and RM signals turn ON, the RM signal (Pr. 5) has a higher priority.
 Maximum of 15-speed operation can be performed. (
