gefran ADV200 Functions Description And Parameters List

102 ADV200 • Functions description and parameters list
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 func-
tion 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 func-
tion 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.
