The drive default setting is Ur I mode which means that the drive will carry out an autotune
NOTE
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,
Motor Too Hot or Over Volts trips.
