Setting Limit Switches on Various XY Stages

There are two sets of limit switches on nearly all XY stages. The two on the top of the stage as shown figures 1a & 1b below are used to limit the range of motion in the Y-axis. The two shown figure 2 a & 2b below are used to limit the range of motion in the X-axis, and these are located on the bottom of the stage. The X-axis limit adjustment setscrews can be accessed by moving the Y-axis towards the front of the microscope. You will need an Allen wrench that was supplied with the stage to make these adjustments.

Do not over-tighten the limit switch’s setscrews. Tighten only until the limit assembly does not move. Over-tightening the upper assemblies causes them to bend outward and even break. Also, ensure that the upper limit assemblies are held firmly against their rail to prevent them from touching or scratching the leadscrew cartridge.

MS-9500 stage

The limit switches are set at the factory to allow the longest range of travel in the X and Y axis. However, the limit switches have been designed to allow you the user to limit the range of travel of the stage. This can be done to prevent the stage from running into the microscope, or parts of the microscope such as the objective shown in the example below. Please note that if you set the limit switches as shown in the example below you will be limiting the stages travel to only scan a 25 x 75 mm slide. This is just an example and the limit switches can be set to cover any range of travel. Please also note that if the limit switches are set such that the stage encounters the mechanical limit of motion before the limit switches are reached the stage does have an over current protection. This is provided only as a safety measure, and the stage can be damaged if the limit switches are not properly set.

Please refer to the above figures 1a ~ 2b, and the figures below to set the limit switches to prevent the SI-INV-STD slide insert from hitting the objective.
