The RPM reading seems wrong

  • Please check the distance between the optical sensor on the optical RPM probe circuit and the reflective tape on the motor. It needs to be less than 5mm.
  • If there is some logo or reflective surface on the motor, please use black tape to shield it
  • If you are using multiple pieces of tape on the rotor, ensure they are equally spaced, and set the number of divisors per turn in the “Setup“ tab. The number of tapes per turn acts as a divisor of the speed value. If you have just one piece of tape (black-white in one turn), set the number of divisors to 1. If you have 2 tapes (black-white-black-white in one turn) set the divisor to 2.
  • For the motor that has a large diameter, please put a longer reflective tape on the motor for the RPM measuring.
  • If you still find the reading is wrong on the GUI, please send us the invoice when you purchased our product, the picture of the circuit, and the description of the issue you met to support@tytorobotics.com. We will give you suggestions for further troubleshooting and solutions for the issue you met.
