Transformation ratio - active
When using an interposing transformer, or if the main supply cable is looped several times
through the current measuring module or the current / voltage measuring module, you can
enter the transformation ratio.
Activate the checkbox if you wish to use this option. The parameterized current setting
continues to correspond here to the actual rated motor current and does not have to be
converted.
The transformation ratio is calculated from the ratio between the rated motor current [A] and
the measured current [A] or any multiple of the ratio.
Note
This parameter is only available when using SIMOCODE pro V
PB above version *E03*.
Transformation ratio - primary
Enter the primary current here, with the "Transformation ratio - active" checkbox activated.
Range: 0 to 8191.875 (default: 0).
Transformation ratio - secondary
Enter the secondary current here, with the "Transformation ratio - active" checkbox
activated. Range: 0 to 15 (default: 0).
Note
In the case of motors with two speeds, the same or different transformation ratios can be set
for each speed, depending upon whether the same or two different interposing transformers
is/are used for each speed.
