Application
Direct drive joint modules are applied in robots, medical equipment, and precision manufacturing to enhance efficiency and accuracy.
Notes
1. Do not disassemble the motor privately;
2. All interfaces do not support hot plugging. You need to plug in the wires before powering on. At the same time, the ground wire of the control signal needs to be connected;
3. The motor is not allowed to suddenly stall during high-speed operation;
4. Do not use overvoltage;
5. Monitor the motor temperature in time, and make the motor work in a reasonable temperature range by reducing power or increasing heat dissipation;
6. Before installing the device, it is recommended to use the host computer to debug the same working conditions first;
7. Update the firmware in time to obtain better motor performance;
