Scaling
Scaling of the input data for current and voltage, which are provided as inputs by EtherCAT Terminals, for example.
In the Beckhoff Information System you will find the documentation of the corresponding PLC function block FB_PMA_Scaling.
In the Beckhoff Information System you will find the documentation of the TF3650 TwinCAT 3 Power Monitoring function with descriptions of the corresponding PLC library.
Configuration parameters
- Resolution Voltage: Resolution of the voltage in bits. Value range: 1-32.
- Max Voltage: Specifies the maximum amplitude of the input voltage.
- Resolution Current: Resolution of the current in bits. Value range: 1-32.
- Max Current: Specifies the maximum amplitude of the input current.
- Factor Current Transformer: Factor of the current trans former. This is calculated by dividing the input current by the output current.
Input values
- Input Voltage 1 ... Input Voltage 3: Raw values of the voltage of the individual phases.
- Input Current 1 ... Input Current 3: Raw values of the current of the individual phases.
Output values
- Output Voltage 1 ... Input Voltage 3: Scaled voltage values of the individual phases.
- Output Current 1 ... Input Current 3: Scaled current values of the individual phases.
