Important Notes
- Operates from 6V to 8.4V DC.
- Use a regulated external power supply with sufficient current capacity.
- Do not exceed the maximum operating voltage of 8.4V.
- Avoid prolonged stalling or mechanical overload to prevent overheating.
- Ensure the servo controller and external power supply share a common ground.
- Confirm the maximum rotation angle before setting mechanical movement limits.
- The servo uses PWM positioning signals and should not be connected to a conventional DC motor driver.
- Torque and current requirements depend on the mechanical load and operating conditions.
