A.1.4 Regeneration resi stors
Dependingon the application, Mic roFlex e100 might require an external regeneration resistor to
bec onnected to pins R1 and R2 of connector X1. The regeneration resistor dissipates energy
duringbrak ing to prevent an over-voltage error occurring.
Baldorpart number RG56 is recommended (56Ω, 44W). However, if the r equired dissipation is
greaterthan this , Baldor part number RG39 may be used, rated at 100W.

WARNING: A regener ation resistor may generate enough heat to ignite combustible
materials. To avoid fire hazard, keep all combustible materials and
flammable vapors away from the brak e resistors. Ensure that the resis tor
hasclearanc e of at least 50mm (2 in) above and below and 26mm (1 in) left
andright.
