Hi,
I'm using the drv8434s to contrrol a step motor with a maximum of 400 steps, It is used to control a valve.
I'm trying to use the stall condition detection in case the valve can't be opened or closed, and I'm not using the learn stall count, so I fixed a value for stall threshold .
I fixed this value for my tests in a condition that I was sure the stall occurred, but for some reason that I don't know, the Fault never occurs.
I intentionally caused a stall from position 187, but at no point I have a nFault error.
I made some captures of the torque count and the value of the driver's registers. The threshold was configured with the value 100, and what I'm reading from the drive is:
Where:
fault 0
diag1 0
diag2 0
ctrl1 a0
ctrl2 8f
ctrl3 0
ctrl4 30
ctrl5 18
ctrl6 64
ctrl7 30
