Set 2 (Quadratic) to obtain a quadratic V/f characteristic curve, useful for controlling pumps and fans, where torque
is proportional to the square of the speed. When this type of curve is selected, the median voltage point is xed at
0.25% of the maximum output voltage (par.2406), and the median frequency point at 50% of the basic frequency
(par.2408).

Setting of the slip compensation. When the asynchronous motor is loaded, the mechanical speed of the motor shaft
varies according to the electric slippage, which affects torque generation. The slip compensation function can be
used to maintain a constant motor shaft speed. Compensation is performed by varying the drive output frequency
as a function of its output current and the motor parameters. Thus, to obtain the best effect, the motor plate data
must be set appropriately, and the correct stator resistance value (Par.2050) must be set or measured using the
self-tuning function, The slip compensation value is calculated automatically during the self-tuning procedure or set
manually in this parameter.
During slip compensation tuning the drive must not be in the current limit condition.

Setting of the slip compensation lter. The value set in this parameter determines the slip compensation function
reaction time. The lower this parameter is set, the greater the slip compensation reaction. If this parameter is too low,
it could cause undesirable oscillations in speed after sudden variations to the applied load.
