(1) Output unit
(a) This device is used to set the unit ([mm]/[inch]) of ball screw.
(b) Set the same unit as used in the real mode (unit in the fixed parameters) for
the ball screw unit.
If the ball screw unit differs unit in the real mode, a mode switching error will
occur at the switching from real to virtual mode.
(2) Ball screw pitch(P)/Number of pulses per ball screw revolution(N
(a) The ball screw pitch connected to the servomotor and number of pulses per
ball screw revolution are displayed.
Number of pulses per ball
screw revolution (N
(b) The travel value per pulse is calculated by the ball screw pitch and number
of pulses per ball screw revolution as the formula below.
