Stop Frequency (Holding time)
At the startup of an inverter, the initial output frequency is equal to the starting frequency 1 specified
by F23. The inverter stops its output when the output frequency reaches the stop frequency specified
by F25.
Set the starting frequency to a level at which the motor can generate enough torque for startup.
Generally, set the motor's rated slip frequency as the starting frequency.
In addition, to compensate for the delay time for the establishment of a magnetic flux in the motor,
F24 specifies the holding time for the starting frequency. To stabilize the motor speed at the stop of the
motor, F39 specifies the holding time for the stop frequency.
If the starting frequency is lower than the stop frequency, the inverter will not output any power
as long as the reference frequency does not exceed the stop frequency.
