* The value in parentheses is the dimension when the magnet protection cover is used.
When two or more magnetic way are used, first secure one of the magnetic way only, and then install the
coil assembly in the available space. If using one magnetic way only with insufficient space to extend the
linear guide up to the position of the coil assembly, temporarily mount a dummy linear guide in line with the
magnetic way's.
• Simplified diagram showing installation of dummy linear guide.
2. Insert a thin nonmagnetic (preferably resin) sheet (approximately 0.5-mm thick) in the air gap between the
coil assembly and magnetic way, and move the coil assembly slowly toward the magnetic way.
