Only valid when FU2-39 [Control mode selection] is
set to Vector_SPD, Vector_TRQ.
Detect the zero speed using I/O-44 [Multi-function
auxiliary contact output selection]. Set Zspd Dect in
I/O-44 [Multi-function auxiliary contact output] to
activate this function.
➨
Note : Sub-board is needed to use multi-function output
