Applied Motion STM23C-3CE - Manual (Page 15)

If you plan to use a regulated power supply you may encounter a problem with regeneration. If you rapidly decel-
erate a load from a high speed, much of the kinetic energy of that load is transferred back to the power supply. This
can trip the over-voltage protection of a switching power supply, causing it to shut down and/or over-voltage your
STM. We offer the RC-050 “regeneration clamp” to solve this problem. If in doubt, buy an RC-050 for your first
installation. If the “regen” LED on the RC-050 never flashes, you don’t need the clamp.
