For three-phase 200V and single-phase 200V series inverters
The braking level setting for the three-phase 200V and single-phase 200V
series should be calculated from the DC braking level

The brake function of the inverter does not provide mechanical holding means.
Otherwise injuries could occur.
F23, F25
Starting Frequency and Stop Frequency
At the startup of an inverter, the initial output frequency is equal to the starting fre-
quency. The inverter stops its output at the stop frequency.
Set the starting frequency to a level that will enable the motor to generate enough
torque for startup. Generally, set the motor's rated slip frequency to F23.
㩷
If the starting frequency is lower than the stop frequency, the inverter will
not output any power as long as the set frequency does not exceed the
stop frequency.
