Appendix B Braking Resistance
B.1 Braking resistance
The motor’s electric potential energy will charge inverter’s capacitance up
reversely if speed of the motor decends too quickly or load of the motor wobbles too
quickly while the inverter is running, which will increase the voltage upon power
modules suddenly and is easy to make the inverter damaged. The inverter will
control it according to load size and performance. You have to connect external
resistance to realize timely energy discharge when the braking is not enough. To
connect external resistance is a kind of energy consumption braking mode, As all the
energy is consumed by the braking resistance.
EDS300 series’
the built-in braking unit is optional and you can add external
braking resistance , But the external resistance need booking.
