F0.00 Braking start voltage 300V
～
2500V
Model
confirmed
☆
This parameter is used to set the starting braking voltage of the braking unit.
220V voltage level, default braking voltage is 350V;
380V voltage level, default braking voltage is 670V;
480V voltage level, default braking voltage is 760V;
F0.01 Braking hysteresis voltage 0V
～
100V 20V
☆
This parameter is used to set the hysteresis voltage during braking.
Generally when setting braking start voltage and braking stop voltage, there must be a
hysteresis loop. Such as settings F0.00=670V,F0.01=20V,when the bus voltage d0.00 is higher
than F0.00, start braking. When the bus voltage d0.00 is lower than (F0.00-F0.01), stop braking.
When the original state is in braking state, and the value of d0.00 is within F0.00 ~ (F0.00-
F0.01), the braking state is maintained.
F0.02 Default brake voltage selection 0
～
2 1
★
This parameter is used to set the default braking voltage for different voltage levels.
When setting to 0, corresponding to 220V voltage level, the default braking voltage is 350V;
When setting to 1, corresponding to 380V voltage level, the default braking voltage is 670V;
When setting to 2, corresponding to 480V voltage level, the default braking voltage is 760V;
F0.03 Braking rate 0%
～
100% 100%
☆
This parameter is used to select the braking rate.
When braking rate is set to 100%, it shows that the braking is fully open, at this time the
braking effect is the best, with the fastest voltage drop, but the brake resistor temperature rises
quickly.
When the braking rate is set to 0%, it shows that the braking is turned off, at this time even
if it reaches the braking condition, the braking does not work.
