Notes
a. Performance specifications are given for the case when the linear stage is mounted as recommended in the
Section 2.3.
b. Deviation from the Ideal Path, Referenced to a Theoretical Straight Line
c. The velocity of the stage can be adjusted to a value equal to or greater than 60% of the maximum velocity
through use of the ASCII message calls described in the protocol document.
d. If an application requires collision with the end-stop pins, which are not contacted normal use, the load should
not exceed 100 g.
e. The linear stage is not designed for continuous operation.
