Software for Initial Operation and Parameterization:
vector7x

The software vector7x is used for parameterizing the frequency converters and for optimizing the application. Various tools allow easy optimization of the controller.

The graph-supported parameterization of the position controller allows optimizing the tool change or the behavior in threading operations.


The parameterization of the speed controller can be optimized while the motor is running
