default value is -45%.
Bypass Volt Prot Limit: When the difference between the bypass voltage and the rated
voltage exceeds the upper threshold for the bypass voltage,
the system determines that the bypass voltage is not normal
and that the bypass is unavailable.
NOTE:
When the voltage level is 380 V, the value range is 10%, 15%, 20%, and 25%
(default).
When the voltage level is 400 V, the value range is 10%, 15%, and 20% (default).
When the voltage level is 415 V, the value range is 10% and 15%(default).
Bypass Freq Tracking Range: When the difference between the bypass input
frequency and the ratedfrequency is greater than this
value, the system determines that the bypass frequency
is not normal, and that the bypass is unavailable.
The value range is 1%, 2%, 4%, 5%, 10%(default).
Bypass rate tracking rate: Inverter frequency tracking to bypass frequency rate.The
value range is 0.5~2, and is 1 by default.
Power Supply upon bypass Over Temp: Specifies whether to start bypass mode when
overtemperature occurs. The default value is Enable.
Bypass Switches Limit: Cross currents occur during the transfer between bypass mode
and normal mode, which impacts the system. This parameter
specifies the number of transfers between bypass mode and
normal mode within 1 hour, which ensures system security. The
value can be 3 to 10, and is 10 by default.
EPO transfers to bypass: Specifies whether to start bypass mode when EPO occurs.
The default value is Enable.
