3.6.2 Use switches to give a start command and a frequency command
(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. 4, Pr. 5 and Pr. 6 to change.)
· Operation at 15-speed can be performed by turning two (or three) terminals simultaneously. (Refer to the
Instruction Manual (applied).)
Changing example
Set "50Hz" in Pr. 4 Multi-speed setting (high speed) and turn on terminal RH and STF (STR)-
SD to operate.
