Transverse 2 Axis
The Transverse 2 axis is also called a Dual Transverse axis. It can be used for either a second cutting station or as an axis
that turns a chuck for pipe or rectangular tube cutting.
Speed 0 To: Specifies speed ranges and customizes the acceleration rates for these speeds. When a speed range that
is lower than the maximum speed is entered, a new range at the maximum machine speed setting is created.
You can set a maximum of 5 speed ranges.
To reduce the number of Speed To ranges, enter the maximum speed in the highest range and the additional
range fields will be removed from the screen.
Proportional Gain: Proportional Gain correlates to elastic stiffness in the control loop. Increasing the proportional gain
increases the static stiffness, but decreases response of the servo loop.
Under proportional loop control, the drive system will apply a restoring torque to the motor in proportion to
the position error of the axis.
With a Proportional Gain too high, the system will be unstable which will result in overshoots and a generally
“nervous” and shaky axis. This is also referred to as a “hot” control loop.
With a proportional gain too low, the system will respond in a loose or sloppy manner. This can be seen in
the test pattern when the outside corners become rounded and the circle segments do not all meet in the
center.
