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 2.25-9 are applied
when VCHK 1 and VCHK2 are applied in the 1.5CB system.
Table 2.25-10 Setting example for 1.5CB system
Output voltage
at VT Bus-bar VT= Phase-B
Line VT= Three phase
Line2 VT= Phase-B
Input voltage
at VCT
Running voltage of SYN1(VS)=Phase-B (Bus-bar VT)
Incoming voltage of SYN1 and SYN2 (Vb)=Phase-B (Line VT)
Running voltage of SYN2 (VS2)= Phase-B (Line2 VT)

Note: Set
V-L2
for the scheme switch [
SYN-VLine
]. This is because V3 and VL2 are in
the same phase. Set
V4
for the scheme switch [
SYN-VLine2
]. This is because V3
and V4 are in the same phase.
