Inverter properties
In the subchapters, the inverters available in DSD are described. The tabular representation makes
it possible for you to easily compare the properties to each other.
10.3.4.1
Frequency inverter
Frequency inverters are suitable for simple, speed-controlled drive tasks, and they are cost-effective.
A speed feedback is not necessarily required.
