F2.08 Dynamic braking initial voltage Setting range: 300~400V/600~800V
This parameter is effective for inverters with built-in braking unit and is used to
define action parameters of inverter’s built-in braking unit. When the inverter’s
internal DC side voltage is higher than dynamic braking initial voltage, the built-in
braking unit acts. If external braking resistor is connected, the inverter’s internal
DC side pumping voltage energy will be released through the braking resistor so as
to reduce the DC voltage. When the DC side voltage reduces to certain value
([F2.08]-50V), the inverter’s built-in braking unit is closed, as shown in Figure
6-14.
