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.

Motor Sound (Carrier frequency and Tone)
Motor Sound (Carrier frequency) (F26)
Changing the carrier frequency
may decrease the motor run-
ning noise, leakage current
from the output lines, and elec-
tric noise from the inverter.
For three-phase 200V and single-phase 200V/100 V series inverters
The braking level setting for the three-phase 200V and single-phase
200V/100 V series should be calculated from the DC braking level I
(A) based on the reference current I

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.
