Make a start and stop with terminals
(external operation)
3.5.2 Use switches to give a start command and a frequency setting
(multi-speed setting) (Pr. 4 to Pr. 6)
POINT
· Start command by terminal STF (STR)-PC
· Frequency command by terminal RH, RM, RL and STR-PC
· [EXT] must be lit. (When [PU] is lit, switch it to [EXT] with
· The initial values of the terminals RH, RM, RL are 50Hz, 30Hz, and 10Hz. (Use Pr. 4, Pr. 5 and Pr. 6 to change.)
· Operation at 7-speed can be performed by turning two (or three) terminals simultaneously. (Refer to
Instruction Manual (applied).)
