encoder window is the number of encoder
counts away from this position the system can
be. If the encoder window is set too small the
system may move continually while searching
the exact position requested.
Check this to enable stage servo. This makes
the stage attempt to stay at the programmed
position. Use this function to overcome drift
in time-lapse experiments.
When in servo mode the controller will
attempt to keep the stage at a particular
position. The servo window is the number of
encoder counts the stage can move before the
controller will respond and correct the
position.
