A.1.4 Regeneration resistors
Depending on the application, MicroFlex e100 might require an external regeneration resistor to
be connected to pins R1 and R2 of connector X1. The regeneration resistor dissipates energy
during braking to prevent an over-voltage error occurring.
Baldor part number RG56 is recommended (56Ω, 44W). However, if the required dissipation is
greater than this, Baldor part number RG39 may be used, rated at 100W.

WARNING: A regeneration resistor may generate enough heat to ignite combustible
materials. To avoid fire hazard, keep all combustible materials and
flammable vapors away from the brake resistors. Ensure that the resistor
has clearance of at least 50mm (2 in) above and below and 26mm (1 in) left
and right.
