Common Issues and Solutions
Step motors do not lose steps under normal conditions. To prevent stalling, motors should be sized appropriately for the load and operated at speeds providing 50% more torque than needed. Stalling does not damage the motor as it results in low output torque and slight current drop.

Manual Linear UniSlide® Assemblies For Nearly Four Decades Velmex... positioning equipment has been used to produce linear and rotational motion in scientific, research, machine, instrument and industrial applications. Hundreds of thousands of UniSlides and BiSlides are in use providing simple, rugged, reliable motion. Velmex applications are limited only by your imagination. For example: measurement, alignment, inspection and QA/QC, optical focusing, antenna alignment, film and animation work, medical and biological analysis, for moving probes, sensors, components, and thousands of other uses. If you need precise, versatile movement in one, two or three dimensions, do it more efficiently and less expensively with a Velmex UniSlide®, BiSlide® or XSlide™. UniSlides are available in nearly 1000 standard models, including Free Sliding, Screw Drive, Graduated Knob and Scale with Vernier. Read position from 0.025” to 1 micron using mechanical or optical mechanisms. Finally, our Rapid Advance models save time. That is an impressive array of products, but the real versatility of UniSlides is their amazing flexibility. Every UniSlide is built to order. Customers are not limited to off the shelf products — you can customize your UniSlide to meet your exact requirements. Rapid/fine motion, thumb screw locks, special finishes, way covers, revolution counters, position encoders or some other feature? We can do it. BiSlide, XSlide and UniSlides Assemblies from Velmex, we’ve put quality into motion. Manual Introduct

Graduated Knob UniSlide Assemblies Measures position to 0.001” or 0.01 mm. Scale and Vernier Screw Drive UniSlide Assembly Your position is measured from the combined readings of the linear scale and engraved knob or drum dial. Each This type adds a precision engraved English or Metric scale and vernier to the Screw Drive UniSlide. Vernier position on the slider is offset to allow placement of a “Y” cross slide without blocking view of lower unit. Travel, as listed in the Price List, is reduced by 0.3” when the vernier cover plate comes into contact with the Rogan knob. See also the Rapid Advance...
