Inverter internal circuit

F

Input

Shorting across F-CC
causes forward rotation;
open causes slowdown and
stop. (If ST is always ON)

R

Input

Shorting across R-CC
causes reverse rotation;
open causes slowdown and
stop. (If ST is always ON)
Shorting across R-CC/F-
CC causes reverse
rotation.

S1

Input

Shorting across S1-CC
causes preset speed
operation.
