Can't calibrate TIM101 PZ Motor

[mathias157]

Hi, i'm having trouble calibrating the PZ motor at initialization.

When my LabVIEW program has finished or the TIM101 is turned off, it resets absolute step values to (0, 0) regardsless of where it ended. If everything runs smoothly this isn't a problem, i'll just end the program with letting it move back to (0, 0). 

However, if an error occurs i need to calibrate it by manually looking the last data of the last absolute step values up - i thought i could do this with the SetPositionSteps function, but nothing happens. This is the initialization part of my code, where i want to be able to calibrate in the case of an error (Note i convert between mm and steps):

Thanks for any help.

Best regards, Mathias
