Input
STF
The terminals are multi-function control terminals,
their function can be set by
parameter P.80~P.84, P.86, P.126, P.550. (The
SINK or SOURCE input approach can be
switched)
The terminal HDI can accept pulse signal (please
refer to the instruction of toggle switch SW11 and
the parameter
P.550
), and the function of it can be
set by P.503.
