Overview
Overview
The LogCommon computes the log10(x) input value. The units of the input value are radians.
The LogCommon is calculated at the update rate, determined by the Evaluate Block.
Note: This block does not support Z21P firmware.
Example
The following example illustrates how to calculate the log10(x) and store it in UserBuffer[0].

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) or background. 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. |
Matlab/Simulink
Simulink Interface
The input to the LogCommon block is a double precision value, with units of radians.
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:
