ECO voltage range

±5/±6/±7/±8/±9/±10
When the deviation of bypass voltage relative
to the rated voltage exceeds the set value, the
system determines that ECO voltage is
abnormal, and the system turns the inverter for
power supply. Note that the ECO frequency
range cannot be greater than the bypass
frequency range. For example, if the bypass
frequency range is set as ±2HZ, then the ECO
frequency range can only be set to ±1HZ and
±2HZ.
