PRODUCT DESCRIPTION
YASKAWA ELECTRIC LKEB-23P7 - Regenerative Resistor Unit
The YASKAWA ELECTRIC LKEB-23P7 is a regenerative resistor unit designed to dissipate excess energy generated by AC servo motors during deceleration or braking operations. This passive component is critical for maintaining stable bus voltage within the servo drive system, preventing overvoltage faults, and enabling high-performance motion control in demanding industrial applications. It is specifically engineered for integration with Yaskawa's Sigma series servo drives, supporting precise control in machinery requiring frequent starts, stops, and rapid reversals.
