When VCHK1 and VCHK2 are used in 1.5CB system, set the scheme switches [SYN-
VBus], [SYN-VLine], and [SYN-VLine2]. For example, the settings in Figure 2.35-9 are applied
when VCHK 1 and VCHK2 are applied in the 1.5CB system.

VCHK Setting
3
Note: Set V-L2 for the scheme switch [SYN-VLine]. This is because V3 and V L2 are in
3
the same phase. Set V4 for the scheme switch [SYN-VLine2]. This is because V3
and V4 are in the same phase.
