 Axis parameter DRIBUSLE (P63) = 0.
Parameters involved in the calculation of the velocity command:
 Axis parameter G00FEED (P38) = Maximum feedrate of the axis = 20000.
 Axis parameter PITCHB (P86) = Leadscrew pitch = 20.
 Motor gear ratio:
axis parameter INPREV (P87) = Input revolutions =3.
axis parameter OUTPREV (P88) = Output revolutions = 1.
 NP121 (drive) = it automatically loads the value of axis parameter INPREV (P87) of the CNC.
 NP122 (drive) = it automatically loads the value of axis parameter OUTPREV (P88) of the
CNC.
 NP123 (drive) = it automatically loads the value of axis parameter PITCHB (P86) of the CNC.
Parameters involved in the calculation of the position feedback.
 axis parameter NPULSES (P8) = number of pulses per turn of the encoder
= 18000 / (3 / 2) = 12000. (only integer values are allowed).
 axis parameter SINMAGNI (P10) = Multiplying factor if the encoder is sinusoidal = 200.
 axis parameter EXTMULT (P57) = Multiplying factor of the feedback = 1.
 Axis parameter PITCHB (P86) = Leadscrew pitch = 20.
