5. Setup

5.1 Physical Connection

Connect the HTS-35H servo to your control board or power supply using the provided cable. Ensure correct polarity for power connections (V+, GND) and proper serial communication lines (TX, RX).

5.2 Wiring for Development Boards

The HTS-35H servo is compatible with various development boards such as Raspberry Pi, Jetson Nano, and Arduino. The three-channel design (top, left, right) facilitates flexible wiring configurations. Refer to the specific wiring diagrams for your chosen development board.

5.3 Setting Servo ID

Each HTS-35H servo has a unique ID, with a default value of 1. For applications requiring multiple servos on a single bus, you must assign a unique ID (0-253) to each servo using the provided debugging software. This prevents communication conflicts.

6. Operating Instructions

6.1 Control via Serial Communication

The HTS-35H servo is controlled using UART serial commands. You will need to implement the communication protocol in your microcontroller code to send commands for position, speed, and other parameters.

6.2 Using Visual Debugging Software

HIWONDER provides visual debugging software to simplify testing and parameter configuration. This software allows you to:

• Control servo rotation and position.
• Monitor real-time data such as position, voltage, and temperature.
• Set various parameters including servo ID, working mode, rotation speed, position deviation, LED light status, temperature alarm, and stalling alarm.

7. Maintenance

• Keep Clean: Regularly clean the servo's exterior to prevent dust and debris from entering the internal mechanisms.
• Avoid Overload: Do not exceed the specified torque limits to prevent damage to the gears and motor. The servo provides feedback to help monitor this.
• Proper Storage: Store the servo in a dry, cool environment away from direct sunlight and extreme temperatures.
• Check Connections: Periodically inspect all wiring and connections for wear or looseness to ensure reliable operation.

8. Troubleshooting

• Servo Not Responding:
  • Check power supply voltage and current. Ensure it meets the 9-12.6V requirement.
  • Verify all wiring connections (power, TX, RX) are secure and correctly oriented.
  • Confirm the servo ID is correctly set and unique if multiple servos are on the bus.
  • Test with the visual debugging software to isolate if the issue is hardware or software related.
• Erratic Movement or Jitter:
  • Ensure the power supply is stable and provides sufficient current.
  • Check for electrical noise in the system; separate power and signal lines if possible.
  • Verify the communication baud rate matches between the servo and the controller.
• Overheating:
  • Reduce the load on the servo.
  • Check for any mechanical binding that might be causing excessive strain.
  • Monitor temperature feedback via software to prevent damage.
