ELECTRICAL DRIVES DRIVE TECHNOLOGY

Industrial three-phase drives

E2.5.3.3

Drives with educational frequency converter (E2.5.3.3) are used with the following objectives:

The importance of frequency converters for manufacturing and operating concepts has never been greater. A frequency converter optimises not only the motor operation, but often the entire driven machine.

This configuration deals with the optimal adaptation of frequency converters and machines without controlling the speed.

Electrical Drives Drive Technology

Industrial three-phase drives

Industrial frequency converters are used for machine optimisation and automation. The equipment includes an industrial, compact frequency converter. The focus of the experiments is on commissioning and parametrising the converter and investigating the machine behaviour.

The manufacturer‘s software is used for parametrisation; programming by hand is possible but not didactically useful given the large number of parameters
