Examples of scenariosRobotic arm, shoulder joint, waist joint, hip joint and knee joint of humanoid robot, aerospace heavy turntable, etc.

When operating under high loads and high speeds, the joint module generates regenerative braking energy. An external "Power Discharge Module (see Power Bleeding Module)" is required to prevent errors and shutdowns due to excessive bus voltage caused by regenerative energy feedback leading to a surge in the power supply voltage.
