5.4.1 Digital input terminals function selection
 Use the following parameters to change the digital input terminal functions. Each terminal may choose any
function between 0~71 (Note 1)
Terminal STF input
function
STF(Inverter runs forward)
STR(Inverter runs reverse)
RL(Multi-speed low speed)
RM(Multi-speed medium speed)
RH(Multi-speed high speed)
AU( Analog terminal 4-5 high priority)
OH External thermal relay actuate
MRS(Stops inverter output immediately)
RT(Inverter second function)
RUN(Inverter runs forward)
STF/STR(use with RUN signal,when ON, motor runs
reverseï¼›when OFF, motor runs forward)
RES(External reset function)
STOP(Use as three line control with RUN signal and STF
-STR signal)
REX(Extend multi-speed to 16 levels)
PO(In “external mode", run programmed operation)
