Overview

The Error block is an Input block that is a source for Position Error data. The output from the Position Error block is the updated Axis Position Error value, as determined by the Subsample Code. The position error is the difference between the axis’s command position and actual position.

The configuration values for this block are as follows:

Axis Number	The number of the axis which is the source of the position error data. This number may be absolute or linked to the Model Number.
Subsample Code	A code which determines the schedule for updating this block (every sample, even samples only, etc.) See Subsampling.
User Data 0	Application-specific data. See User Data Storage.
User Data 1	Application-specific data. See User Data Storage.

The Output of the ErrorPosition block is the Axis Position error value. The position error is the difference between the axis’s command position and actual position.

This block has no inputs.

The Axis Number of the axis providing the position error data is determined by the Axis Number parameter. This number can be absolute or linked to the Model number.

The block has two user data fields (User Data 0, User Data 1) to store application-specific data for convenient storage and retrieval. See User Data Storage for details.

The block's update schedule is determined by the Subsample Code (See Subsampling). The following Parameter Dialog Box can be opened by double-clicking on the block in a Simulink Model:
