Bandwidth
You can use this parameter to set the maximum permissible deviation of the
measured voltage U
actual
from the desired value U
desired
.
In order to set the correct value, the transformer step voltage and nominal
voltage must be known. Note that a large bandwidth will result in a large
control deviation.
The bandwidth must always be greater than the following value:
