Thank you for this information. From this perspective the best way I can think of to monitor the timing would be to output a breakpoint signal everytime the motor reaches it's target position. For this approach you would need a counter device like the
PXI-6602 or the counters of any Multifunction DAQ Device to measure the time between the pulses generated at the breakpoint outputs.
If you combine this with blending you should get the best results possible.
