Dynamic Braking
Dynamic Braking is used to prevent over-voltage faults during
rapid deceleration or constant speed run on cyclic overhauling
applications.
Dynamic Braking dissipates regenerated energy in the form of
heat. When using a DBR, use thermal protection.
The resistive load is connected across terminals PA and PB (non-
polarized). Using a low-value, high-wattage resistance as a load
for the generated current, the resistive load dissipates the
induced energy.
Dynamic Braking helps to slow the load quickly; it cannot act as a
holding brake.
The Dynamic Braking function may be set up and enabled by
connecting a braking resistor from terminal PA to PB of the ASD
and providing the proper information at
, and
.
