Axes – Transverse or Rail
The following screen is identical for both the traverse and rail setup screens.
The CNC comes with both an advanced position and velocity servo loop. The following
parameters are available to help configure the servo loops for your specific drive and
mechanical system.
Speed 0 To
This parameter allows the technician to input selected speed ranges to customize the
gains for the various speeds selected.
Note: These speed parameters are directly tied to the Speed To field for the acceleration
rates previously noted on the Speeds setup screen. Changing these speed parameters
replaces the Speed To values entered at the Speeds setup screen.
Proportional Gain
Proportional gain correlates to elastic stiffness in the control loop. Increase the
proportional gain to increase the static stiffness, but decrease the response of the servo
loop.
