VCHK1 setting for 1CB system
2.25.4
When the VCHK1 is applied to 1CB system, OVB and UVB check the voltage of a Bus-bar,
whereas OVL and UVL check the voltage of Line, as described earlier. The Bus-bar and Line
voltages are obtained in the VCT
[SYN-VLine] in accordance with the phase(s) of input-voltage(s). The following are the setting
examples when VCHK is used in 1CB system.
Note: For more information on VCT, see
