Actual Value Acquisition - Siemens Sinamics GM150 6SL3835-2LN44-2AA0 Operating And Installation Instructions

Consider the following properties during the configuration:
● Short-circuit voltage u
● Transformer taps for voltage adjustments:
● The voltages and insulation for the secondary-side windings must be dimensioned as

secondary windings with respect to ground. Because the transformers generally have
temperature evaluation systems in the windings, the specified test voltage is required for
strengthened insulation. If no control circuits have been installed in the windings, the test
voltage in accordance with the basic insulation is sufficient.

Actual value acquisition

Actual current and voltage values are recorded by the AVT combination module
combination module converts analog signals into digital signals and forwards them to the PSA.
The signals are transferred to the PSA via fiber-optic cables.
