Maximum
bypass voltage
When the difference between the
bypass voltage and the rated
voltage is greater than this value,
the system determines that the
bypass voltage is abnormal and
that the bypass is unavailable.
When the voltage level is 380 V,
the value can be +10%, +15%,
+20%, or +25%. The default
value is +15%.
When the voltage level is 400 V,
the value can be +10%, +15%, or
+20%. The default value is
+15%.
When the voltage level is 415 V,
the value can be +10% or +15%.
The default value is +10%.
