High response speed interpolator unit for position control
Capable of 40 to 1000 divisions
Produces quadrature A/B signals with a resolution from 2 µm to 125 µm, when used in combination with the optionally available Digiruler PL25 head unit and the SL110/130 scale unit (scale signal wavelength: 5 mm), or with the PL60 and the SL331 scale unit (scale signal wavelength: 2 mm).
MJ100: Supply voltage 5 V input Line driver (EIA-422) output
MJ110: Supply voltage 12 to 30 V input Open collector (lOL=50 mA) output
MJ100 also generates U/ V/ W phase output with a period of reproduced DIGIRULER signal (5 mm with PL25; 2 mm with PL60)
