V/f control (vector control)
6.2 Voltage boost
Drive functions
Function Manual, 11/2017, 6SL3097-4AB00-0BP5
303
Note
The voltage boost affects all V/f characteristics (p1300).
Note
Excessive motor temperature rise as a result of excessive voltage boost
If the voltage boost value is too high, this can result in an excessively high motor winding
temperature increase
- and therefore result in a shutdown (trip).

= p0305 (rated motor current · p0395 (actual stator resistance) · p1310 (permanent voltage
