StA2
R/W
Frequency loop stability, motor 2
Unit: 1%
Factory setting: 20
Adjustment range: 1 to 100
Parameter active only if UFt2 = n or nLd.
Used to adapt the return to steady state after a speed transient (acceleration or deceleration),
according to the dynamics of the machine.
Gradually increase the stability to avoid any overspeed.

2043 / 1A
SLP2 R/W
Slip compensation, motor 2
Unit: 1%
Factory setting: 100
Adjustment range: 0 to 150
Parameter active only if UFt2 = n or nLd. Used to adjust the slip compensation value fixed by
nominal motor speed.
The speeds given on motor rating plates are not necessarily exact.
If slip setting < actual slip: the motor is not rotating at the correct speed in steady state.
If slip setting > actual slip: the motor is overcompensated and the speed is unstable.

LAF
R/WS
Forward limit switch
(1)
Factory setting: 0
Function active only if LAC = L2 or L3 (page
).
0 = "nO": Not assigned
129 = "LI1": Logic input LI1
130 = "LI2": Logic input LI2
131 = "LI3": Logic input LI3
132 = "LI4": Logic input LI4
133 = "LI5": Logic input LI5
134 = "LI6": Logic input LI6

LAr
R/WS
Reverse limit switch
(1)
Factory setting: 0
Function active only if LAC = L2 or L3 (page
).
0 = "nO": Not assigned
129 = "LI1": Logic input LI1
130 = "LI2": Logic input LI2
131 = "LI3": Logic input LI3
132 = "LI4": Logic input LI4
133 = "LI5": Logic input LI5
134 = "LI6": Logic input LI6

2056 / 4
LAS
R/WS
Type of limit switch stop
Factory setting: 2
Function active only if LAC = L2 or L3 (page
).
0 = "rMP": On ramp
1 = "FSt": Fast stop
2 = "nSt": Freewheel stop
9723
2043 / 18
UFr2
R/W
IR compensation/Voltage boost, motor 2
Unit: 1%
Factory setting: 20
Adjustment range: 0 to 100
For UFt2 = n or nLd: IR compensation. For UFt2 = L or P: Voltage boost.
Used to optimize the torque at very low speed (increase UFr2 if the torque is insufficient).
Check that the value of UFr2 is not too high for when the motor is warm (instabilities can occur).
Modifying UFt2 will cause UFr2 to return to the factory setting (20%).
9720
2043 / 15
FLG2 R/W
Frequency loop gain, motor 2
Unit: 1%
Factory setting: 20
Adjustment range: 1 to 100
Parameter active only if UFt2 = n or nLd. The FLG2 parameter adjusts the drive’s ability to
follow the speed ramp based on the inertia of the machine being driven.
Too high a gain may result in operating instability.
