KUE
Speed ratio
Kv
Servo gain factor, a control variable in a control loop.
Leadscrew error compensation
Compensation for the mechanical inaccuracies of a leadscrew participating in the feed. The
control uses stored deviation values for the compensation.
Limit speed
Maximum/minimum (spindle) speed: The maximum speed of a spindle may be limited by
values defined in the machine data, the -> PLC or -> setting data.
Linear axis
The linear axis is an axis, which, in contrast to a rotary axis, describes a straight line.
Linear interpolation
The tool travels along a straight line to the destination point while machining the workpiece.
Load memory
For the CPU 314 of the -> PLC, the load memory is equal to the -> work memory.
Look ahead
With the Look Ahead function, a configurable number of traversing blocks is read in advance
in order to calculate the optimum machining velocity.
Look-ahead detection of contour violations
The control can recognize and signal the following types of collision:
1. The path distance is shorter than the tool radius.
2. The width of the inner corner is smaller than the tool diameter.
Machine
Control operating area
Machine axes
Axes, which exist physically on the machine tool.
