6.3 Parameter Setting
Parameters can be set and changed with the PC software.
Parameter settings and changes become valid by performing a “software reset” by the PC software or
turning the power supply off and back on again.
6.3.1 Basic Settings
This section describes the parameters that must be set in order to operate P-Driver.
(P-Driver can be operated simply by setting these parameters, if only positioning operation is required.)
(1) Electronic Gear
These are parameters for determining the amount of unit movement of the actuator per 1 pulse of the
command pulse-train input.
Amount of unit movement for linear axis = Minimum amount of movement (e.g. 1, 0.1, 0.01 mm)/pulse
Amount of unit movement for rotational axis = Minimum amount of movement (e.g. 1, 0.1, 0.01
deg)/pulse
