22 Regeneration Warning
A rotating motor has kinetic energy, regeneration occurs when the kinetic energy that was stored in the motor
during motion is returned to the system during deceleration. This energy must be absorbed by the DC bus
Capacitators, which in turn raises the bus voltage or dissipated by friction.
It is possible under certain conditions that regenerative action will raise the bus voltage above the RGM
drives rated maximum voltage. If this occurs the drives will shut down with an over voltage fault. If
regeneration does shut down the drive, the user will either need to modify the application by slowing down the
process, or use a power supply with regeneration capability.
