| Examples of scenarios | Robotic arm, surgical robot, and elbow joint, ankle joint, neck joint and shoulder joint of humanoid robot, 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.
