Overview

Description

The Analog Input block is used to read analog input values from inputs from Node or Motor I/O.

The Channel Number defines which analog input channel to use.

The input is read at the update rate, which is specified by the Evaluate Block

Example

The following example illustrates a simple PID Filter controlling Axis 0. It demonstrates how to abort an axis based on an Analog Input, and enable/disable the amplifier based on a Digital Input.

Note the Analog Input 0 from Node 1 is run through a Deadband filter. If the output of the Analog block exceeds 7500 (the specified Deadband Limit), the output of the Deadband is non-zero, triggering the Axis Abort.

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 Node Number of the Analog Input specifies which SynqNet Node is the source of the input.

The Channel defines which analog input channel on the node is read.

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 is opened by double-clicking on the block in a Simulink model:
