Hi there,
I would be grateful if someone could shed some light on this for me. I have read various tutorials on stepper motors but have not been able to clear up a question I have.
I understand that if a force greater than the holding torque of a motor is applied to it then the motor position could become out of synch with the position held by the controlling program.
A way around this could be to advance until a limit switch is triggered and then to reset it's position from this known position. But this causes a lot of disruption in the application.
An better solution would be to interrogate the motor controller on the motor's position and then correct the deviation. My question is whether the motor controller device holds the actual physical position of the motor or the position where it thinks it is, i.e. (before it was forced).
Once again I would be thankful for any help.
