Title: AXSCRIPT - Input Leg - Power Flow Enabled - Question
Post by: Mike Nash on April 29, 2021, 06:14:25 PM

I'm migrating a project from DO-06 to BX that runs a stepper.

I see in Help where the instruction can be interrupted, but what happens to a move or timer or whatever, at the moment the Input Leg goes false? And where/how does it get back into the script when enabled?

I mostly want to know if a trapezoidal incremental move is going to decel to zero mid-move, finish the move first, or just turn off the axis outputs?

And how it completes the step when re-enabled?

I need it to interrupt the move by ramping to stop, then finish the move when re-enabled.

Look at the Axis structure .suspend member that will do what you want as long as it hi the motion will ramp to a stop and stay stopped once it clear ramp back up and finish the move.

Thanks,

I finally spotted the .Suspend, but had already done it with the regular trapezoidal and just loading the distance to complete the move before enabling again. That's how I had done the D0-06.

The 3 axis stepper system I made I wrote a whole different program for each axis just for testing and just the motor on the floor

Why guess if it might crash.....which I did several times anyways  :)
