Description
inverter frequency is unstable.
Description
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.
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.
When the difference between the
bypass input frequency and the
rated frequency is greater than
the specified value, the system
determines that the bypass
frequency is abnormal, so the
bypass is unavailable.
