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
over-voltage 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.

+5V Keep-Alive Feature:
+5Volts can be fed to the +5V terminal to keep the logic alive when the DC bus voltage is removed. This is very useful
when an encoder is present, as the position of the system is then known when the DC bus is re-applied. An internal volt-
age fault will have to be cleared and the motor re-enabled when the DC bus is re-applied. A .4 Amp or larger supply is
required for the keep-alive supply.
