The drive default setting is Ur I mode which means that the drive will carry out an
autotune every time the drive is powered-up and enabled. If the load is not going to be
stationary when the drive is powered-up and enabled, then one of the other modes
should be selected. Not selecting another mode could result in poor motor performance
or OI.AC, It.AC or OV trips.
