Reginaldo, da uma olhada na pagina 8 do manual: 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. This can trip the overvoltage protection of a switching
power supply, causing it to shut down. 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.
Pelo que entendi, estes drivers podem trabalhar regenerando, apenas tem de cuidar da parte das fontes, por que se for fonte chaveada e for protegida, a tensão vai aumentar e a fonte pode desligar.
