Overview

Task

When a target position is approached, the position monitoring function monitors whether the actual position reaches an exact stop window (tolerance range) within a specific time.

If a configurable limit is exceeded, the CNC generates an error message and the axis is stopped.

Characteristics

The position lag monitor checks the correct functioning of the position controller.

For example, this can identify the following problems:

• Mechanical changes to axes, e.g. increased friction due to damaged bearings or guides
• Errors in the axis position measuring systems

Parametrisation

The position monitor is configured for each individual axis in the axis parameter list.
