Application
The 4Nm direct-drive joint motor is used in high-precision direct drive scenarios such as collaborative robots, precision turntables, and medical equipment, and has zero backlash and high response characteristics.

Note
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.
