-SLP
Adjusts the slip compensation around the value set by the nominal motor
speed. This parameter only appears if parameter UFt = n in the drC- menu.

-FLG
Frequency loop gain
Linked to the inertia and the resistive torque of the driven mechanism :
- machines with high resistive torque or high inertia : gradually reduce the
gain in the range 33 to 0
- machines with fast cycles, low resistive torque and low inertia : gradually
increase the gain in the range 33 to 100. Too high a gain may result in
operating instability.

-IdC
Level of DC injection braking current
After 5 seconds the injection current is peak limited at 0.5 Ith if it is set at a
higher value.

-tdC
DC injection standstill braking time
If the time is increased to 25.5 s, "Cont" is displayed. The DC injection is then
continuous at standstill.

-JPF
Skip frequency prevents prolonged operation at a frequency range of 2 Hz
around JPF. This function prevents a critical speed which leads to resonance.
Setting the function to 0 renders it inactive.
