listed in the following table.
Voltage Class
Default Overvoltage Threshold
Single-phase 220 V
400.0 V
Three-phase 220 V
400.0 V
Three-phase 380 V
830.0 V
Three-phase 480 V
890.0 V
Note:
The default value is also the upper limit of the frequency inverter's internal overvoltage protection voltage.
The parameter becomes effective only when the setting of bb-28 is lower than the default value. If the setting is
higher than the default value, use the default value.
bb-29
Under voltage threshold
Default
Model dependent
Setting Range
200~2000V
It is used to set the under voltage threshold of Err09. The default values of different voltage classes are listed in the
following table.
Voltage Class
Nominal Value of under voltage
threshold
Single-phase 220 V
200 V
Three-phase 220 V
200 V
Three-phase 380 V
350 V
Three-phase 480 V
450 V
bb-30
Brake unit use ratio
Default
100.0%
Setting Range
0%~100%
It is valid only for the frequency inverter with internal braking unit and used to adjust the duty ratio of the braking unit.
The larger the value of this parameter is, the better the braking result will be. However, too larger value causes great
fluctuation of DC bus voltage during the braking process.
