Time delay for motion control

[Terahertz]

Hi, I=92m using LV to move a linear stage stepwise. I use =93Wait until
next ms multiple=94 in a =93for=94 loop to specify the time delay between
the steps. When the time is set to 2000 ms, things are fine. But when
it is set to < 1500 ms, the time delay is significantly shorter
between the first two steps, although the delays between subsequent
steps are OK. I need to have the time delay < 1500 ms and consistent.
What should I do?
Many thanks,
THz
