| ControllerName | Bind this block to an OpCtrl block by entering the same 'Controller Name' as specified in the OpCtrl block The OpCtrl block controls initialization of the settings of one specific FPGA card in the system. |
|---|---|
| DataOut port number | Set the number of the DataOut port to be controlled by this block, in the range [1:64] for the VC707, TE0741 and TE0741 OP48xx FPGAs and [1:32] for all others. |
| Slot infos | This non-editable parameter displays the physical location of the digital input channels related to the selected DataOut port, as obtained from the parsing of the configuration file. |
| Available channels | This non-editable parameter specifies the maximum number of quadrature encoder input values returned by the DataOut port as defined in the RT-XSG bitstream. Each quadrature encoder input value comes from the decoding of a set of A, B and Z input signals. |
| Number of Encoder Signals | Set the number of quadrature encoder input values to be returned by the block. The value must be less than or equal to the value of the 'Available channels' parameter. |
| Auxiliary Output type | Select the type of the second output. Raw stands for raw data received from FPGA and Angle for the current angle value. |
| Rate Unit | Select between Hz and RPM (Revolution per Minute). |
| Angle Unit | When the 'Auxiliary output' parameter is set to 'Angle', this parameter is editable. Three units are available for angle: degree, radian and revolution. |
| Sample time (s) | This parameter allows the user to specify the block sample time in seconds. The default value is 0, which specifies a continuous sample time (note that the sample time is borrowed from the separated subsystem) while -1 specifies an inherited sample time. A functionality block and its associated controller block must execute at the same sample time. |
| Resolution | This parameter stands for the number of cycles of the A and B signals per revolution. It is necessary to set this parameter to the right value to get a good estimation of rate. |
| Clockwise rotation | This parameter is used to decode the direction of rotation. |
| Minimal rate | This parameter is used to detect the null rate. Under this value, Rate is assumed to be null. This parameter uses the unit specified by 'Rate Unit'. |
