F23 to F25 Starting Frequency 1, Starting Frequency 1 (Holding time), and
Stop Frequency
At the startup of an inverter, the initial output frequency is equal to the starting frequency.
The inverter stops its output when the output frequency reaches the stop frequency.
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.
Starting Frequency 1 (F23)

F23 specifies the starting frequency at the startup of an inverter.
- Data setting range: 0.1 to 60.0 (Hz)
Starting Frequency 1 (Holding time) (F24)

F24 specifies the holding time during which the inverter runs at the starting frequency 1 at the
time of startup.
- Data setting range: 0.00 to 10.00 (s)
Stop Frequency (F25)

F25 specifies the stop frequency at the stop of the inverter.
- Data setting range: 0.1 to 60.0 (Hz)
If the starting frequency is lower than the stop frequency, the inverter does not
output any power as long as the reference frequency does not exceed the stop
frequency.
