Implement s-ramp on stepper

[UDanz.1]

Hi, I need to implement an s-ramp for a stepper motor.

Currently using L6482.

Can you please point me in the direction of the correct controller + driver?

Thanks!

The question has been moved from the "STM32 Motor Control" section to the "Motor Control Hardware" section (the question is not about the STM32 MC SDK).

Hi @UDanz.1​,

You can use the L6482 in Step-clock mode and drive it with an external MCU.

In Step-clock mode the motor motion is defined by the step-clock signal applied to the STCK pin.

At each step-clock rising edge, the motor is moved one microstep in the programmed direction and the absolute position is consequently updated.

Consider that when the system is in Step-clock mode, the SPEED register is set to zero and the motor status is considered stopped regardless of the STCK signal frequency. So you have to change the TVAL_HOLD value according your requirements.

I hope this post can help you; if so, consider to mark it as best answer by clicking the label "Select as Best".
