Only be effective for the inverter that built-in braking unit.
Used to adjust the duty ratio of braking unit, the higher the usage rate is, the higher the duty ratio of
braking unit is, the stronger the braking effect is, the bigger the inverter bus voltage fluctuation in
braking process is.

Over-excitation control can inhibit the bus voltage rise, avoid the overvoltage fault. The bigger the
over-excitation gain is, the better the inhibition effect is; buy over-excitation gain is too large, easy to
cause the output current increases, need to weigh in the application. Increase the over-excitation filter
coefficients to slow the speed of inverter response over-excitation control, on the contrary, you can
speed up the inverter response the speed of over-excitation control.

Select the inverter frequency change mode in the process of start and stop.
0: Straight-line acceleration/deceleration
Output frequency increase or decrease according to the linear. VD560 provide four kinds of
deceleration time. Select by multi-function digital input terminal (F5-01~F5-05).
