ML605EX1 Resolver In

Block

Mask

Description

The ML605EX1 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 ML605EX1 block by entering the same 'Controller Name' as specified in the OpCtrl ML605EX1 block. The OpCtrl ML605EX1 block controls the initialization of the settings of one specific ML605 development board 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 a 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

Value

Description

0

No error.

-1

Block could not be matched with an OpCtrl ML605EX1 block (check the 'Controller Name' value), or ML605 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 ML605 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 ML605 card than the value specified in the 'Data outport width' parameter. Extra data were discarded.
