L6470, move and speed change

Posted on October 08, 2013 at 11:09

Hi.

Using L6470 I need to move to absolute position with the possibility to change speed during motion. I need the Soft Stop (or something similar) when reaching the target.

Speed change during motion is possible using Run command but not using Move command (Move has the deceleration I need when reaching the target).

I already tried 2 solutions but I don't like them both:

1) Using Run and checking continuously if the motor is approaching the target position to issue a Soft Stop at the appropriate time. This is tricky because speed changes often and the ''stop time'' varies accordingly.

2) Using Run + Hard Stop when reaching target pos: this is a mechanical stress to avoid.

Is there any another possibility I'm missing?

Thank you in advance

Alessandro
