Use Switches To Give A Start Command And A Frequency Command (Multi-Speed Setting) (Pr. 4 To Pr.6) - Mitsubishi Electric FR-F700 Series Instruction Manual

Operation by the start command of the
terminal block (external operation)
3.6.2 Use switches to give a start command and a frequency command
(multi-speed setting) (Pr. 4 to Pr.6)
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).)
