Unit increments
Based on the unit inc, only values without the last 3 digits are
output.
Unit 0.01 mm/s
With the digital measuring system (DGCI, DDLI), only speeds
that have no after-decimal places result, since here 5 μm is
always calculated.
For the potentiometer or encoder (DNCI, DDPC), after-decimal
digits are putput, since for the potentiometer the effective
stroke length is divided by 65535 and for the encoder an
increment is calculated as 4.8828 μm.
