Ur S: Stator resistance is measured each time the drive is enabled and run
Ur: No measurement is taken
Fd: Fixed boost
Ur A: Stator resistance is measured the first time the drive is enabled and run
Ur I: Stator resistance measured at each power-up when the drive is enabled and run
SrE: Square law characteristic
In all Ur modes, the drive operates in open loop vector mode.
