Overview

Overview

The Feedback Velocity block is an Input block that is a source for velocity data. The output from the Feedback Velocity block is the raw Encoder Feedback Velocity (counts/sample) value updated as determined by the Subsample Code.

The following parameters are used to configure this block at load time:

Motor Number The number of the axis which is the source of the position data. This number may be absolute or linked to the Model Number. Encoder Number The number of the encoder on the motor which is the source of the position. A value of 0 specifies the primary encoder, while a value of 1 selects the secondary encoder. 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 Feedback Velocity block is the raw Encoder Feedback Velocity (counts/sample) value. This block has no inputs.

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

The Encoder Number parameter specifies which of the motor’s feedback devices to use.

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:

The Feedback Velocity block is used to connect the inputs of a model. This block has no configurable parameters.
