2.1.2 Limiting 

Stage 

Motion

The provided ceramic driving plate should not exceed the stage. It
must be supported by a solid even backing along all its length, in
order to avoid breaking when motor is pressed against it.

The Ceramic driving plate should also be at least 20 mm longer
than the stage travel length, otherwise the motor finger tips might
be damaged.

If the above requirements are not met, limit the stage travel
distance using end stops.
