Digital input/ output parameter group03
PARAMETER DESCRIPTION 89
5.4.1 Function selection of digital input
Use the following parameters to select or change the digital input terminal functions. Any function from 0 to 45 can
be selected by each terminal (Note 1).
STF(the inverter runs forward)
STR(the inverter runs reverse)
RL(Multi-speed low speed)
RM(Multi-speed medium speed)
RH(multi-speed high speed)
The external thermal relay operation
MRS(the instantaneous stopping of the inverter output)
RT(the inverter second function)
RUN(the inverter runs forward)
STF/STR(it is used with RUN, when STF/ STR is “on”, the
inverter runs reverse;when STF/STR is “off”, the inverter
runs forward)
RES(external reset function)
STOP(it can be used as a three-wire mode with the RUN
signal or the STF-STR terminal)
REX(multi-speed set (16 levels))
PO(in “external mode", programmed operation mode is
chosen)
