可用的驱动功率作为输入电压的功能
Input under-voltage rollback
In the event that the input voltage falls below 90 %, the
attached description provides details of drive limitations.
当输入线电压降至其额定值的90％以下时

在下面的fiure。在66％的输入电压下，最大值
drive power is limited to 50 % and is quickly reduced to a
略微负值（regen限制）为65％。这个限制
forces the drive to absorb power from the motor and
maintain the (power cell) DC-bus voltages in case the
input voltage recovers during MV ride-through. The limit is
