UFr [IR compensation]
1)
25 to 200% 100%
This parameter can be accessed if [motor control type] (Ctt) is not [V/f Reg 2P] (UF2) and [V/f Reg 5P] (UF5) .
Enables increase in the optimization of the torque at very low speed ( [IR-compens.] (UFr) if the torque is not sufficient).
Make sure that the value of [IR compens.] (UFr) is not too high in relation to the heated motor (risk of instability).
SLP [Slip compensation]
1)
0 to 300% 100%
This parameter can be accessed if [motor control type] (Ctt) is not [V/f Reg 2P] (UF2) and [V/f Reg 5P] (UF5) .
Allows the adjustment of the rated motor speed by entering the set slip compensation.
The speeds given on motor nameplates are not necessarily exact.
• If slip setting is < actual slip: The motor is not rotating at the correct speed in steady state, but at a speed lower than the reference.
• If slip setting is > actual slip: The motor is overcompensated and the speed is unstable.
1) This parameter can also be accessed via the [SETTINGS] (SEt-) menu.

VC2 [Vector control 2pt] [No] (nO)
This parameter cannot be accessed if [Motor control type] (Ctt) is not [Sync. Motor.] (SYn) .
nO [No] (nO) : Function not active.
YES
[Yes]
(YES) : Function active.
Is used in applications in which the motor rated speed and frequency must be exceeded to optimize the operation for constant power, or if the
maximum voltage of the motor must be limited to a value below the line voltage.
The voltage/frequency profile must be adapted based on the capabilities of the motor for operating at maximum voltage (UCP) and maximum
frequency (FCP).
