DRV8711: How to use PWMMODE mode

Annie Liu

Part Number: DRV8711

Hi team,

The PWMMODE of the OFF Register register uses the Bypass indexer, use xINx inputs to control outputs. The customer wants to know how to control the stepper motor with this setup? How to operate the official GUI?

Thanks,

Annie

Hey Annie,

When you check the "PWMMODE" box on the GUI it will set the bit in the Time OFF register to 1 to use the bypass indexer. After checking that box you can adjust the duty cycle for each input (AIN1, AIN2, BIN1, BIN2) and it should send the PWM signal as you move the sliders. I'm not sure what you're asking about the bypass indexer
