Mask
Description
The OP7160EX1 Resolver In is based on the basic resolver which is a two-pole resolver. The Resolver In block is used to retrieve the angle and speed from the resolved signals.
Parameters
| Controller Name | Bind this block to an OpCtrl OP7160EX1 block by entering the same 'Controller Name' as specified in the OpCtrl OP7160EX1 block. The OpCtrl OP7160EX1 block controls the initialization of the settings of one specific OP7160 card in the system. |
|---|---|
| DataOut port number | Enter the index of the DataOut port to be controlled by this block, in the range [1:32]. |
| Slot info | This non-editable parameter displays the physical location of the analog input channels related to the selected DataOut port, as obtained from the parsing of the configuration file. |
| Calibration Mode | When this checkbox is selected, the mask parameters used in the Resolver In block are available as block inputs. This mode allows the tuning of parameters during execution. |
| Damping factor (Ksi) | This parameter specifies the filter's damping factor. |
| Natural Frequency (w0) | This parameter specifies the filter's natural frequency. The unit is Hertz (Hz). |
| Use internal carrier for demodulation | When selected, the Resolver In block generates its own carrier for demodulation. |
| Internal Carrier Delay | This parameter is the delay for the application of the internal carrier with the resolved signals (sine and cosine). It should be between 0 and 20e-6. This input is expressed in seconds. |
| Internal Carrier Frequency | This parameter specifies the carrier frequency. It should be between 0.01 and 90000 Hz. |
| Internal Carrier Amplitude | This parameter specifies the amplitude of the carrier that will be outputted by the Resolver In block. It should be between 0 and 16 V. The resolution is 1 mV. |
| Internal Carrier Offset | This parameter specifies the offset of the carrier that will be outputted by the Resolver In block. It should be between -16 V and 16 V. The resolution is 1 mV. |
| External Carrier Amplitude | This parameter specifies the amplitude of the carrier expected by the Resolver In block. It should be between 0 and 16 V. The resolution is 1 mV. |
| External Carrier Offset | This parameter specifies the offset of the carrier expected by the Resolver In block. It should be between -16 V and 16 V. The resolution is 1 mV. |
| Sine Amplitude (V) | This parameter specifies the amplitude of the resolved sine signal. It should be between 0 and 16 V. The resolution is 1 mV. |
| Sine Offset | This parameter specifies the offset of the resolved sine signal. It should be between -16 V and 16 V. The resolution is 1 mV. |
| Cosine Amplitude | This parameter specifies the amplitude of the resolved cosine signal. It should be between 0 and 16 V. The resolution is 1 mV. |
| Cosine Offset | This parameter specifies the offset of the resolved cosine signal. It should be between -16 V and 16 V. The resolution is 1 mV. |
Inputs
When Calibration Mode is selected, the Resolver In block displays the following inputs:
| Ksi | This input specifies the filter's damping factor. |
|---|---|
| w0 | This input specifies the filter's natural frequency. The unit is Hertz (Hz). |
| Sine Amp | This input specifies the amplitude of the resolved sine signal. It should be between 0 and 16 V. The resolution is 1 mV. |
| Sine Off | This input specifies the offset of the resolved sine signal. It should be between -16 V and 16 V. The resolution is 1 mV. |
| Cos Amp | This input specifies the amplitude of the resolved cosine signal. It should be between 0 and 16 V. The resolution is 1 mV. |
| Cos Off | This input specifies the offset of the resolved cosine signal. It should be between -16 V and 16 V. The resolution is 1 mV. |
| Carrier Amp | This input specifies the amplitude of the carrier that will be outputted by the Resolver In block. It should be between 0 and 16 V. The resolution is 1 mV. |
| Carrier Off | This input specifies the offset of the carrier that will be outputted by the Resolver In block. It should be between -16 V and 16 V. The resolution is 1 mV. |
| Carrier Freq | This input is displayed when the Resolver In block uses an internal carrier. It represents the carrier's frequency and it should be between 0.01 and 90000 Hz. |
| Carrier Del | This input is displayed when the Resolver In block uses an internal carrier. It is the delay for the application of the internal carrier with the resolved signals (sine and cosine). It should be between 0 and 20e-6. This input is expressed in seconds. |
Outputs
| Angle | Angle represented with 16-bit precision. Range of values: [0, 360] |
|---|---|
| Speed | Speed in rotations per second (Hz). |
| Car_Pu | When Calibration mode is selected, this output returns the scaled carrier wave (when Carrier Amplitude and Offset are well tuned) |
| Status | This output returns the following values: |
| Value | Description |
|---|---|
| 0 | No error. |
| -1 | Block could not be matched with an OpCtrl OP7160EX1 block (check the 'Controller Name' value), or OP7160 card initialization problem. |
| -2 | Data reception timeout. This error can be caused by model synchronization errors. |
| -3 | Data reception error: the block received less data from the OP7160 card than the value specified in the 'Data outport width' parameter. Missing data were replaced by 0. |
| -4 | Data reception error: the block received more data from the OP7160 card than the value specified in the 'Data outport width' parameter. Extra data were discarded. |
