Description
Position Output of the Laser position
Intensity Output of the Laser intensity value
Speed Output of the Laser actual speed
20 bit position data, 11 bit speed. The number of
Position +
data bits must be set to 31. Max. possible
Speed
resolution = 0.1 mm.
After the position data a toggle-bit is following.
Position + This changes its condition (high->low or
Toggle-Bit low->high) after each SSI cycle and means, that
the position value was calculated new.
