Parameters for ES930: Current PS In Tab

The power output stages, which are offered by the ES930 for use cases such as controlling actuators, are integrated in the module via half-bridge switches. This makes individual extensions to the hardware system obsolete.

In this tab you can configure the current measurement in the output path for these half-bridge switches in order to monitor the correct functioning of the power stages. The current measurement provides the present value of the electric current and different additional filter options.

Note

Using current measurement disables the use of one analog input, digital input, or thermo channel.

The following list shows the parameters in the Current PS In tab of the ES930:

Shows a consecutive number for each entry in the hardware configuration table.

You cannot edit this field.

Use this checkbox to enable or disable this signal for further configuration steps.

Disabled signals will not be available in the Experiment Environment.

You can also use the context menu commands Enable All Channels and Disable All Channels to enable or disable all channels at once that are displayed on the selected tab.

Shows the name of the measurement variable assigned to this channel. The name can be edited. It must be unique for the whole configuration.

Enter the unit according to the signal to be measured.

The selected unit appears in the corresponding measure windows.

Defines the default acquisition rate necessary for your measurement task.

The acquisition rate can be selected for the six channels together. It is used as default rate within the measuring environment (e.g. INCA Experiment Environment), but you can overwrite it (e.g. in INCA's Configure Variables dialog).

Note

A large number of channels with high acquisition rate can push your system to its performance limits.

If an event raster is defined in the Events tab, the event raster (e.g. BEvent) for the corresponding channel is also available in this field.

Defines whether the digital filter is switched on or off.

When the digital filter is turned off, the field turns red to indicate that aliasing effects might occur, i.e. that signals can be distorted. In the Filter Frequency column the string --- is displayed to indicate that no filter frequency is selected.

Note

If an event raster is selected in the Rate column, it is not possible to select a digital filter, and this field is disabled.

If the value in the Digital Filter column is set to On, you can select the filter frequency for the digital filter. Which frequencies are available depends on the selected rate.

Note

Detailed descriptions of the filter characteristics can be found in the User's Guide of the device.

Enter the lower physical value according to the sensor used.

You can find this value in the datasheet of your sensor.

Note

You can only enter a value if the formula used has the type "Identity" (Sensor = phys) or "Linear", i.e. the sensor connected to this channel is subject to linear calibration. However, if you use a special conversion formula, this field is empty.

Enter the upper physical value according to the sensor used.

You can find this value in the datasheet of your sensor.

Note

You can only enter a value if the formula used has the type "Identity" (Sensor = phys) or "Linear", i.e. the sensor connected to this channel is subject to linear calibration. However, if you use a special conversion formula, this field is empty.

Enter the value of the lower sensor signal according to the lower physical value.

Note

You can only enter a value if the formula used has the type "Identity" (Sensor = phys) or "Linear", i.e. the sensor connected to this channel is subject to linear calibration. However, if you use a special conversion formula, this field is empty.

Enter the value of the upper sensor signal according to the upper physical value.

Note

You can only enter a value if the formula used has the type "Identity" (Sensor = phys) or "Linear", i.e. the sensor connected to this channel is subject to linear calibration. However, if you use a special conversion formula, this field is empty.

When you click into this field, an editor opens where you can create special conversion formulae.

Note

If you use a special conversion formula, the fields of the Phys bottom, Phys top, Sensor bottom and Sensor top parameters are empty.
If you modify the values in the fields Phys bottom, Phys top, Sensor bottom or Sensor to the formula is automatically adapted.

Enter the lower limit of the expected physical measurement range.

This value is used together with the values of the Phys bottom, Sensor bottom and Formula parameters to calculate the amplification factor.

The highest amplification factor possible is selected to ensure that none of the connected channels is overloaded.

Enter the upper limit of the expected physical measurement range.

This value is used together with the values of the Phys top, Sensor top and Formula parameters to calculate the amplification factor.

The highest amplification factor possible is selected to ensure that none of the connected channels is overloaded.

Shows the lower physical limit of the measurement range actually possible for this channel.

This value is determined by the values of the Phys bottom, Sensor bottom and Formula parameters as well as by the actual measurement range of the module.

You cannot edit this field.

Shows the upper physical limit of the measurement range actually possible for this channel.

This value is determined by the values of the Phys top, Sensor top and Formula parameters as well as by the actual measurement range of the module.

You cannot edit this field.

Enter any comment for that signal. The comment may be displayed along with the signal in some dialogs in the rapid prototyping or measurement and calibration tool used.

Note

You can only enter a comment for signals that are selected in the Sel. column.
