For a $$3$$-axes $$CNC$$ table, the slide along the vertical axis of the table driven by a $$DC$$ servo motor via lead screw nut mechanism. The lead screw has a pitch of $$5mm.$$ This lead screw is fitted with a relative (incremental) circular encoder. The basic length unit $$(BLU)$$ of the slide along the vertical axis of the table is $$0.005mm.$$ When the table moves along the vertical axis by $$9mm.$$ The corresponding number of pulses generated by the encounter is
