Limit Switches on Velmex Motorized Linear Stages
Limit Switches are electro-mechanical devices that regulate the motion on positioning devices. On Velmex products they are primarily used to stop/turn off the motor when activated preventing over-travel of the carriage/slider. They also can be used to send an event signal. Limits connect with controllers, such as the Velmex VXM™ Step Motor Controller. Velmex uses several different types.
• Adjustable (moveable) limits, which are standard on BiSlide Assemblies and optional on XSlide and UniSlide Assemblies.
• Fixed end of travel limits, which are standard on XSlide Assemblies and optional on UniSlide Assemblies. These are not adjustable.
• Internal limits which are only available on the UniSlide MB90 Series.
• Home switches, which actually reference a point rather than limit travel, are used on Rotary Tables and can be used on XSlide Assemblies.
It is possible to purchase motor-driven Velmex stages without limits, however, it is not recommended and it may effect the warranty should you incur any damage.
The following at-a-glance chart outlines the Velmex Stage and what limits can be used.
