3 Comprehensive Tuning

The comprehensive tuning section provides a simplified methodology for tuning critical parameters and selecting the appropriate resistors for the following pins in MCT8316AT.

  • RMP_1

  • RMP_2

  • LDANGLE

  • CONFIG_1

  • ILIMIT

  • CONFIG_3

  • SLEW_RATE

Note: Resistor value for CONFIG_2 pin is defaulted to 75 kΩ, ±5%.

Testing is required to find the optimal resistor value for the motor. This includes replacing the resistors on the MCT8316AT pins, as necessary.
