The VCHK can have the decision of synchronism between the running voltage and the
incoming voltage when the following items (i) to (iv) are satisfied:
(i)
Voltage magnitudes
The magnitude of the running voltage and the incoming voltage are greater than
the SYN1 and SYN2 settings:
For SYN1 setting:
VB ≥ [
VCHK-OVB
] and VL ≥ [
VCHK-OVL
]
For SYN2 setting:
VL2 ≥ [
VCHK-OVL2
] and VL ≥ [
VCHK-OVL
]
(ii)
Voltage difference
The differences of the magnitude between the running voltage and the incoming
voltage (ΔV1 and ΔV2) are smaller than the SYN1 and SYN2 settings:
For SYN1 setting:
ΔV1 ≥ | VB − K × VL | ≤ [
SYN1-dV
]
For SYN2 setting:
ΔV2 ≥ | VL2 − K × VL | ≤ [
SYN2-dV
]
Note: The VCHK calculation should be achieved correctly even if respective
rating voltages in VB, VL, and VL2 are not identical. Thus, the VCHK
function has a matching factor (K) designed to adjust the respective rating
voltages when they are not identical. The matching factor (K) is calculated
automatically using the setting values of VCT ratios; the K is generated
