Zero zones for speed optimizing
A. Zero zones for fine points
When positioning to fine points, the control system checks that each axis is within its zero
zone before the next movement is begun. This is done to achieve the positioning accuracy
required. This check is normally not performed when positioning to coarse points.
The size of the zero zone for the different types of fine points are stored as system -
parameters. The system works with zero zones in the form of monitor increments (a certain
rotation of the motor shaft in question). Checking and changeing of the size of the zero
zones, is performed
in mm.
Programmed position
Small zero zone
Large zero zone
Extra large zero zone
Size of
zero zone
Route of TCP
The size of the zero zone expressed in mm is almost in agreement with the actual size under
the following conditions only:
- The movement is performed with maximum extended robot arm and with TCP 0 active.
This means that in most cases a smaller real zone is obtained than that expressed in mm.
Description
The system contains a parameter with a zero zone value for each type of fine point:
