Tip!
Cases of application for this function:

• Operation of reluctance motors or synchronous motors during controlled acceleration

(reduction of natural frequencies caused by wrong excitation).

• Adaptation of the voltage requirement for the motor, depending on specific load

conditions.

Proceed as follows to open the dialog for parameterising the motor control:

1. »Engineer« Go to the Project view and select the 8400 StateLine controller.
2. Select the Application parameters tab from the Workspace.
3. Select the motor control "10: VFCplus: V/f definable" from the Overview dialog box in the

Motor control list field:

4. Click the Motor control V/f definable button to change to the OverviewMotor control V/f

dialog box.

• This dialog level only shows a simplified signal flow with the most important

parameters.

• When you click the >>More details button in the left-most position, a signal flow with
