0: Every change of a motor parameter leads to a recalculation based on the as-
cending rule.
1: Every motor parameter will stay on it’s value even if a different parameter got
written. So no recalculation based on the ascending rule.

If the data for 'Motor rated power factor' C1.10 is not available on the motor
nameplate, keep its default setting '0.00: Automatically identified'. However, the
rotational auto-tuning performance may be affected.
Motor slip frequency configuration
This function is used to compensate the deviation between the motor speed and
the synchronous speed caused by the load. In addition, the mechanical perform-
ance of the motor can be improved with this function.
For V/f control, slip compensation does not work in acceleration, deceleration,
DC-braking processes or regenerative mode.
