  • Digital Potentiometer MCP41100 and Arduino

    HelloI am working on a CNC machine. I am using a brushless dc motor as a spindle ( Motor specs. 18V, 30A, 21000rpm).I will be using a motor driver to control the spindle motor. Driver specs: Working Voltage: DC 10-50VOutput Voltage: Linearity Under LoadMaximum Current: 60APersistent Current: 40AFixed frequency: 25KhzSpeed Control Range: 0%~100%Speed Regulation Method: Potentiometer (Tape Switch)Speed Control Type: Regulating CurrentForward Reversal: SupportSupport Motor: DC Brush Motor(Driver board link : https://www.banggood.com/DC-10-50V-122448V-60A-PW...But the problem is the driver board uses a 10K pot, and my cnc controller board gives out PWM singal via only two pins i.e +10V and GND. so how do i connect those two PWM pins to the microchip to eleminate the pot on the motor driver...
