Regeneration

If you plan to use a regulated power supply you may encounter a problem with regeneration. If you rapidly

decelerate a load from a high speed, much of the kinetic energy of that load is transferred back to the power

supply. is can trip the overvoltage protection of a switching power supply, causing it to shut down. Unregu-

lated power supplies are beer because they generally do not have overvoltage protection and have large

capacitors for storing energy coming back from the drive. ey are also less expensive. See previous section on

Connecting the Power Supply

for details on the RC-050 regeneration clamp.
