For example, with a resolution as fine as 8 nm, speeds of over 250 mm/s are achievable. Aerotech's Dedication to the Science of Motion is reflected in some of the unique features of the MXH series. Not only does the MXH boast industry-leading data rates, but for atypical resolution requirements, Aerotech can create custom multiplication factors. -

Note: MXH multipliers are available in -A and -B versions as factory supplied configurations. Multiplication selections are possible in 0.25 increments up to MXH256, which multiplies into an integer after x4 (i.e. 0.25 or 0.5, 1.25, 33, etc. Unacceptable values are 1.7, 2.4, etc.). From MXH256 to MXH512, multiplication selections are possible in x1.0 increments. Chapter 1 www.aerotech.com... -

2. At high speeds, a chirping noise can be heard when the table is accelerating and decelerating. 3. Using Aerotech’s application software as a diagnostic tool, a harmonic or a sub-harmonic of the fundamental encoder frequency may be seen in the position error or velocity error plots of the axis scope window. -
