Start and stop using terminals (External operation)
5.2.2 Setting the frequency by switches (three-speed setting) (Pr. 4 to Pr. 6)
POINT
 Switch ON the STF (STR) signal to give a start command.
 Switch ON the RH, RM, or RL signal to give a frequency command.

REMARKS
 Initial values of terminals RH, RM, and RL are 60Hz, 30Hz, and 10Hz. (To change, set Pr. 4, Pr. 5 and Pr. 6.)
 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. (
