(multi-speed setting) (Pr. 4 to Pr.6)
[Connection diagram]
POINT
· Start command by terminal STF (STR)-SD
· Frequency command by terminal RH, RM, RL and STR-SD
· [EXT] must be lit. (When [PU] is lit, switch it to [EXT] with
.)
· The initial values of the terminals RH, RM, RL are 60Hz, 30Hz, and 10Hz. (Use

,
Pr. 5
and Pr. 6
to change.)
· Operation at 15-speed can be performed by turning two (or three) terminals simultaneously.
