(1) Unit setting
(a) This is the setting for the units (mm/inch) for the ball screw.
(b) Set the same units as used in the real mode (unit setting in the fixed
parameters) for the ball screw units.
If the ball screw units and units in the real mode are different, a mode
switching error will occur on switching from the real mode to the virtual
mode.
(2) Ball screw pitch (P)/Number of PULSES per ball screw revolution (N
P
)
(a) These are the settings for the pitch of the ball screw connected to the
servomotor and the number of PULSES when the ball screw rotates one
revolution.

(b) The travel value per PULSE is calculated from the ball screw pitch and
number of PULSES per ball screw revolution.
