b1.23
Range: 0~100
Default: 100
Dynamic brake
use ratio
Unit: %
The larger the value of this parameter is, the better the braking result will
be. However, too larger value causes great fluctuation of the drive bus
voltage during the braking process. If it is set to 0, dynamic brake is
invalid.d0.13 needs to be set as 0 before using the dynamic brake
function.
b1.24
Range: Model dependent
Default: Model dependent
Dynamic brake
voltage
Unit: V
Different drive voltage grade have different range and default value,
please see the table below:
Table 6- 2 the relation of drive voltage grade with dynamic brake voltage

Note:
In actual application, you can combine dynamic braking, flux
braking and overvoltage stall control to optimize braking effect.
For example:
Set V/F over-excitation gain(d0.09) to 77 then make the over excitation
become to 1.2 times of standard when drive in decelerating.It can
increase the excitation and increase the braking capacity.
Set overvoltage stall protective voltage(d0.14) to 720V.
Set overvoltage stall gain(d0.13) to 10.
Set Dynamic brake voltage(b1.24) to 700V.
Set dynamic brake use ratio to 50%, you can modify the value
according to actual power consumption on braking resistor.
It not only cat meet the requirements of rapid deceleration but also
can avoid overvoltage in the rapid decelerating.
