2.4.2Regeneration resistor (Dynamic Brake resistor)

The 2.5A and 5A MintDrives both have internally fitted regeneration resistors*. For 7.5A, 10A and 15A MintDrives, an external regeneration (Dynamic Brake) resistor must be installed to dissipate excess power from the internal DC bus during motor deceleration.

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.

Table 2 - Baldor regeneration resistor catalog numbers

All the regeneration resistors listed in section D.1.4 on page 139 are completely assembled and enclosed in a IP21/NEMA 1 rated enclosure.

*Additional resistors connected to R1 and R2 will be connected in parallel with the internal resistor.

2.4.2.1Regeneration resistor mounting

The regeneration resistor should be mounted near the top of an enclosure to maximize heat dissipation. When the motor regenerates, the yellow DB On LED on the front panel of the MintDrive will illuminate while the voltage is exceeding the safe limit. See section D.1.4 on page 139.
