This parameter is related to the security protection of the inverter.
If this parameter is set to 1, if the time run command is effective when power on (for exampl
e, the terminal run command is closed before power on), the drive does not respond to the ru
n command, you must firstly cancel the run command , after run command is again effective
the drive response. Prevent the danger occurs when power on or fault reset, motor repose to t
he run command unknowingly.
If this parameter is set to 0, the inverter power off without a fault condition (for example, the
terminal run command is closed before power on), the drive response to run commands.

The inverter's multifunction output DO will output ON signal when the operating
frequency is higher than the detected value, conversely DO output ON signal is canceled.
The above parameters is used to set the detected value of output frequency, and the
hysteresis value after the output is canceled. Of which, F7.24 is the percentage of the
hysteresis frequency in the detected value(F7.23). The below figure is the schematic diagram
of FDT.
