Data area for a linear axis:
"Type" column: I = input field, O = output field
Field name
Ref. point
coordinate
Software lower
limit
Tool length
offset
Type
I
Description
The reference point coordinate must lie between the lower and upper
software limit switches or at the exact position of one of these switches.
I This value specifies the lower software limit switch. This value must be
lower than that for the upper software limit switch and must also be
such that the axis cannot reach the lower hardware limit switch during
deceleration.
Software upper
limit
I This value defines the coordinate of the upper software limit switch. This
value must be greater than that for the lower software limit switch and
must also be such that the axis cannot reach the upper hardware limit
switch during deceleration.
I This value is used to compensate for tool wear. Each target position in a
traversing (machining) program is offset by this value. The tool length
offset is added to any previous tool offset, and can be used repeatedly.
