REMARKS
y The initial values of the terminals RH, RM, RL are 3000r/min, 1500r/min, and 300r/min. (Use Pr. 4, Pr. 5 and Pr. 6 to change.)
y In the initial setting, when two or three of multi-speed settings are simultaneously selected, priority is given to the set speed of
the lower signal.
For example, when the RH and RM signals turn ON, the RM signal (Pr. 5) has a higher priority.
y Maximum of 15-speed operation can be performed. ( Refer to Chapter 4 of the Instruction Manual (Applied).)
