voltage to inverter inside, which will increase DC bus voltage and surpass max voltage. When
you choose Over /less voltage stall protection and it is valid, Inverter detects DC side voltage, if
the voltage is too high, the inverter to stop deceleration (the output frequency remains
unchanged), until the DC side voltage is below the set value, the inverter will re-implement the
deceleration
With braking models and external braking resistor, this function should be set to “0”.

Only in the inverter deceleration process, and detected high-voltage DC bus exceeds a
predetermined value, the dynamic braking will be implemented
2 : General Type
Under any state, when the inverter detected high-voltage DC bus exceeds a predetermined
Value, the dynamic braking will be implemented.
When the inverter is running on emergency deceleration state or load great fluctuation, it
may appear over-voltage or over-current. This phenomenon is relatively prone to happen when
the motor load inertia is heavy. When inverter The inverter internal DC bus detected voltage
exceeds a certain value, the output brake signal through an external braking resistor implement
energy-braking function. Users can select inverter models with a braking function to apply this
feature.
