Kollmorgen A-80737-2 Regeneration Control Board

Description:

The Kollmorgen A-80737-2 Circuit Board ACS-REG2-225 is a regeneration (regen) control board designed for Kollmorgen servo amplifier systems. It monitors the DC bus voltage and controls regenerative braking circuitry to safely dissipate excess energy generated during motor deceleration, protecting the drive from overvoltage conditions. Commonly installed in Kollmorgen SBD2 servo amplifiers, CNC machinery, automated production equipment, robotics, and industrial motion control systems where controlled regenerative braking and DC bus protection are required. Maintenance teams and system integrators use this circuit board for OEM replacement, servo drive repair, retrofit projects, and industrial motion control maintenance. 

Applications:

The Kollmorgen A-80737-2 is used in servo drive systems to regulate regenerative energy during motor deceleration. It is commonly found in CNC machine tools, packaging equipment, printing presses, robotics, material handling systems, and other precision motion control applications utilizing Kollmorgen SBD2 servo amplifiers. The regeneration board protects the DC bus by activating the braking circuit whenever regenerated energy causes the bus voltage to rise above its preset threshold.
