FAQ

Q1: Is TF-Luna available with 3.3V or other power supply voltage?

A1: Sorry, it is not available for the time being. The Standard power supply of TF-Luna is 5V±0.1V. If you have any further requirement, please contact our sales person to consult a customization design matter.

Q2: TF-Luna will heat up after operating for a while. Is it broken?

A2: This is the normal operating condition of the product. The temperature of the chip and circuit board will slightly up after a continuous operation, which is a normal case.

Q3: Can TF-Luna be connected with Arduino or Raspberry Pi for use?

A3: Yes, it can. TF-Luna adopts serial communication protocol so that it can connect to any control board supporting serial port communication.

Electronic Protection: Over Load: Triggers when exceeding 80% of stall torque for 25ms. Clear by sending new position command. Customizable threshold and duration. Over Current: Triggers when current >2A for 2s. Output disabled until new position command received. Customizable current threshold. Over Voltage: Triggers when voltage <4V or >8V. Auto-resets when voltage returns to normal range. Customizable voltage range. Over Hot: Disables torque output when temperature >70°C. Operating Modes: Mode 0: Position Servo (Default) - 0~360° absolute position control Mode 1: Speed Closed-loop - Maintains speed under load Mode 2: Speed Open-loop - Speed decreases with load Mode 3: Stepping Mode - Relative position movement Multi-Loop Mode: ±7 absolute rotations at highest precision (non-volatile). Resolution expandable. Step Middle Position: One-click calibration for any 360° installation position. Set middle position by writing 128 to address 40. Command Signal: Digital Packet Protocol Type: Half Duplex Asynchronous Serial Communication ID range: 0-253
