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.

Motor control list field:
4. Click the Motor control V/f definable button to change to the Overview  Motor control V/f
dialog box.
• This dialog level only shows a simplified signal flow with the most important
