Overview

The Absolute Value block outputs the absolute value and magnitude of the input value. Strictly positive, the output value matches the input value without regard to its sign. Fractional values are preserved.

The block is calculated at the update rate, determined by the Evaluate Block.

The configuration values for this block are as follows:

Evaluate Block	This block allows you to specify whether the block executes Every Sample, Every Other Sample (Odd or Even), or Every Fourth Sample (and specify the First, Second, Third, or Fourth). This provides greater flexibility in controlling the execution of a model and to preserve performance for other areas of motion control.
User Defined Block Priority	When selected, allows you to enter a Priority Code to modify Execution Ordering of this block. For more information, see Block Execution Order and User Defined Block Priority.
Priority	For an explanation of how the Priority field is used by the MechaWare Model Downloader, see Block Execution Order and User Defined Block Priority.
User Data 0	Application-specific data. See User Data Storage.
User Data 1	Application-specific data. See User Data Storage.

The Absolute Value block outputs the absolute value of the input value.

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

The block's update schedule is determined by the Evaluate Block. The following Parameter Dialog Box can be opened by double-clicking on the block in a Simulink model:

Declaration

Public Method

	class ABSBlock: public virtual Block { public: // User accessible coefficients };
	Required Header: mechaware.h

Description

The Absolute Value block performs a floating point absolute value operation on the input, effectively stripping its sign, forcing a positive value of the same magnitude.
