A.1.9 Regeneration resistors
Some MintDrive
II
models (2.5A and 5A) are fitted with an internal regeneration resistor (see
sections 2.2.1 and 8.1.5). Additional (external) regeneration resistors can be fitted to these
models using the R1 and R2 pins of connector X1/X1A. Resistors connected in this way will
be in parallel with the internal resistor.
If an internal resistor is not present, a regeneration resistor should be installed to dissipate
energy during braking to prevent an over-voltage error occurring.

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. Baldor regeneration
resistors are neither internally fused nor thermally protected and, under extreme
conditions, can cause a fire hazard if not suitably protected or rated for the
application.
