Repeat positioning accuracy and positioning accuracy are important parameters for customers to buy linear motor module, so, what are the two accuracy factors affected by it? 

       The first thing to know about this problem is to understand the structure of a linear motor module, linear motor module is usually composed of linear motor, slide block group, base, structure parts, encoder, driver (optional) and so on. 

       The positioning accuracy, repetitive positioning accuracy and resolution of linear motor module are closely related to each other. In general, the accuracy of repeated positioning, is much higher than the positioning accuracy, such as 2-3 times, generally not more than 10 times, and the positioning accuracy, between the resolution and repeated positioning accuracy. Because the repeated positioning accuracy of the system is related not only to the accuracy and resolution of the encoder (displacement sensor) , but also to mechanical system errors, such as guidance system, transmission system, structural rigidity, etc. , it will reduce the positioning accuracy and, to some extent, affect the repeated positioning accuracy. The relationship among resolution, positioning accuracy and repeat positioning accuracy can be improved by improving the resolution, and of course, can also improve the repeat positioning accuracy. In general, the precision of repeated location is much higher than that of location, and the precision of location is between the resolution and the precision of repeated location.
