Delta VFDB 4132 Series Brake Module Instruction Sheet

About this manual

The VFDB 4132 series brake modules are used with Delta AC motor drives to absorb regeneration energy during motor deceleration. The modules dissipate this energy in dedicated brake resistors and must be installed with BR series brake resistors for optimal performance.

The document provides detailed specifications, wiring guidelines, voltage setting tables, jumper configuration for master/slave operation, and safety warnings such as overheat alarm activation and required grounding. It also includes dimensions and a list of compatible brake resistors.
