(Note 1) Hardware Detection: Items for which all IGBTs are directly turned off by hardware. Software Detection: Items for which the
protective interlock operation is performed by detecting errors, via software.
(Note 2) "O" marks in the interlock operation fields can be selected by parameter setting.
"*" indicates that the equipment outputs the trip signal to the input main circuit breaker.
“x” indicates the phase (U,V,W).
