5 .9 Regene ration
5 .9 .1 Rege nerative Energy Ove rview
When a m ot or and load decelerate rapidly, kinetic energy of the load drives the
m ot or shaft energy back to the drive; this is called regenerat ive energy
, or
regeneration. This energy must dissipated or absorbed
Regenerative energy that is not dissipated is added to the electrical energy
already stored in the capacitors of the bus module. If the capacitors are capable
of storing the energy, the system does not require a regeneration resistor
.
I n som e cases, often due to a high inertial mismatch between the load and
m otor, excessive energy is added to the capacitors, causing the voltage on the
capacit ors t o reach the over-voltage threshold, which then disables the drive. To
prevent over-voltage, and potential damage to the system , the excessive
regener at ive energy must be dissipated by a regeneration resist or.
