duration exceeds the limit of P9-30 When the load loss detection time is reached, the inverter
outputs the load loss fault Err34. Of course, it is also possible to select the action state after
the load is dropped through P9-24.

This function is only valid in vector and non-torque control mode, 100% of P9-31 corresponds
to the maximum frequency P0-14.
When the inverter detects that the actual speed of the motor deviates from the set speed, the
speed deviation value is greater than the excessive speed deviation detection value P9-31,
and the duration is longer than the excessive speed deviation detection time P9-32, the inve-
rter reports Err29. P9-23 can also define the inverter action state after the fault.

This function is only valid in vector and non-torque control mode, 100% of P9-34 corresponds
to the maximum frequency P0-14.
When the inverter detects that the actual speed of the motor exceeds the maximum speed of
the inverter, the excess value is greater than the over-speed detection value P9-33, and the
duration is longer than the over-speed detection time P9-34, the inverter reports Err43 fault.
When the over-speed detection time is 0.0s, the over-speed protection is invalid.

This parameter is used to realize the overload protection below 110% of the rated current of
the motor, and should be used in conjunction with P9-00~P9-02.
