Appendix 4 Braking resistance
1.1 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 only need to connect
external braking resistance to realize timely energy discharge when the braking
function is needed. To connect external resistance is a kind of energy consumption
braking mode, as all the energy is consumed by the braking resistance.
We can add built-in braking unit for EDS1000-2S0004~2S0037 with additional
cost upon receival of your requirement; EDS1000-4T0007G~4T0150G have
built-in braking unit, but no braking resistance.
When braking function needed, please connect external braking resistance
according to below table.
