Input/
output Function Specifications Inverter internal circuit
FInput
Shorting across F-CC
causes forward rotation;
open causes slowdown and
stop. (If ST is always ON)
RInput
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.
S2 Input
Multifunction programmable contact input
Shorting across S2-CC
causes preset speed
operation.
Dry contact input
15Vdc - 5mA or less
*Sink/source selectable
