Parameters
The parameters of the module are used to configure the EtherCAT Terminal as well as to set the internal evaluation and determine the measured variables.
Name | Data Type | Default | Unit | Description |
|---|---|---|---|---|
|
|
|
| Scaling factor for voltage measurement, for adapting the raw values to the actual voltage (e.g. for voltage transformers). |
|
|
|
| Measuring range of the voltage measurement, for setting the maximum measured voltage of the EtherCAT Terminal (690 V for EL3783, 100 V for EL3783-0100). |
|
|
|
| Threshold value for the voltage measurement, below which the measured values are considered inaccurate or invalid. |
|
|
|
| Defines the behavior for inaccurate voltage values (e.g. set to zero). |
|
|
|
| Scaling factor for the current measurement to adapt the raw values to the actual current (e.g. for current transformers). |
|
|
|
| Measuring range of the current measurement for setting the maximum measured current of the EtherCAT Terminal (Auto for automatic current measuring range switching). |
|
|
|
| Threshold value for the current measurement, below which the measured values are considered inaccurate or invalid. |
|
|
|
| Defines the behavior for inaccurate current values (e.g. set to zero). |
|
|
|
| Nominal frequency of the system (e.g. 50 Hz or 60 Hz) as a reference for frequency-dependent calculations. |
|
|
|
| Time constant of the first filter for smoothing the frequency measurement. |
|
|
|
| Time constant of the second filter for smoothing the frequency measurement. |
|
|
|
| Number of grid half-waves used to calculate effective values. |
|
|
|
| Number of grid half-waves used for the analysis of harmonics. |
|
|
|
| Update rate of the calculated phasors (pointer variables for voltage and current). |
