I’m in the middle of a ramp step in AVA and the device has unexpectedly stopped ramping. Why?

This indicates that the experiment is paused.

It’s possible that another device, in a step set to end during the ramp, is waiting for end conditions to be met before it can finish and move on to the next step, as this would pause the Schedule.  This is shown on the right hand side of the example below.

Here, the circulator cannot heat fast enough to reach its end setpoint in the specified time.  As the default end conditions for a circulator step are for both duration and setpoint to be achieved, the step cannot immediately move on.  Meanwhile, the overhead stirrer, which is ramping, is paused at its current stirring speed.
