If the voltage system is 230 V (400 V in the case of three-phase outputs), the values
include 10%, 15%, and 20%.
If the voltage system is 240 V (415 V in the case of three-phase outputs), the values
include 10% and 15%.
The parameter is configurable after the inverter shuts down.
−
Min. voltage
parameter
Lower threshold for the bypass voltage. If the difference between the bypass
voltage and the rated output voltage exceeds this value, the system determines that
the bypass voltage is abnormal and that the bypass is unavailable. The values
include 10%, 20% (default), 30%, 40%, 50%, and 60%. The parameter is
configurable after the inverter shuts down.
−
Frequency range
parameter
Bypass frequency range. When the difference between the bypass input frequency
and the rated frequency is greater than this value, the system determines that the
bypass frequency is abnormal and that the bypass is unavailable.
The frequency range must be greater than the ECO frequency range. The values
include ±0.5 Hz, ±1 Hz, ±2 Hz (default), ±3 Hz, ±4 Hz, ±5 Hz, and ±6 Hz. The
parameter is configurable after the inverter shuts down.

You can use the ECO function only if power grid conditions are good and the voltage and frequency
fluctuation is within the specified ECO voltage and frequency range.
−
Max. voltage
parameter
Upper threshold for the ECO voltage. In ECO mode, when the difference between
the bypass voltage and the rated voltage is greater than this value, the system
determines that the ECO voltage is abnormal and transfers to normal mode. The
values include 5%, 6%, 7%, 8%, 9%, and 10% (default). The parameter is
configurable after the inverter shuts down.
−
Min. voltage
parameter
Lower threshold for the ECO voltage. In ECO mode, when the difference between
the bypass voltage and the rated voltage is greater than this value, the system
determines that the ECO voltage is abnormal and transfers to normal mode. The
values include 5%, 6%, 7%, 8%, 9%, and 10% (default). The parameter is
configurable after the inverter shuts down.
−
Frequency range
parameter
ECO frequency range. In ECO mode, when the difference between the bypass
frequency and the rated frequency is greater than this range, the system determines
that the ECO frequency is abnormal and transfers to normal mode.
