The inverter provides dierent funcons by means of which the drive behaviour can be fur-
ther opmised.

V/f voltage boost ^ 130
l
The parameterisable voltage boost makes it possible to
improve the starng performance for applicaons requiring
a high starng torque.
Skip frequencies ^ 131
l l l
By means of the three parameterisable skip frequencies,
crical frequencies can be suppressed which lead to
mechanical resonances in the system.
Opmising the stalling behaviour ^ 133
l
For special motors which enable an operaon in the eld
weakening range, the behaviour in the eld weakening
range can be adapted to the motor.
Slip compensaon ^ 135
l
In case of a load, the speed of an asynchronous motor
decreases. This load-dependent speed drop is called slip.
The slip compensaon serves to counteract the load-
dependent speed loss.
Oscillaon damping ^ 137
l
The oscillaon damping serves to reduce the oscillaons
during no-load operaon which are caused by energy oscil-
lang between the mechanical system (mass inera) and
the electrical system (DC bus).
l
For controlling a permanent-magnet synchronous motor, the
pole posion - the angle between the motor phase U and
the eld axis of the rotor - must be known. This funcon
serves to detect the pole posion for the currently acvated
motor encoder.
