Mitsubishi HG-KR43BG7-1-21 AC Servo Motor for HG Series

The Mitsubishi HG-KR43BG7-1-21 (HG-KR43BG7-1-21) is an AC motion servo component engineered for demanding automation setups within the Mitsubishi HG Series and MELSERVO systems. Designed to deliver stable and accurate motion control, this unit operates with a rated output of 600 W (0.6 kW) and a rated current of 3.2 A across a 200 V AC to 230 V AC supply voltage class. It integrates a built-in dynamic brake and an integrated regenerative resistor to absorb deceleration energy and ensure rapid, dependable stopping performance in cyclic operations. The device supports high-speed SSCNET III/H communication capability, enabling synchronized multi-axis control and seamless interoperability across automated machinery. It is fully compatible with direct drive motors as well as linear encoder feedback devices, providing versatile application options for precision positioning, assembly lines, robotics, packaging machinery, and machine tooling. As a legacy motion component that has transitioned out of production, it remains a vital replacement unit for maintaining ongoing plant operations and minimizing costly downtime in established production environments.
