Parameters described in this page can be accessed by:
Code Name / Description Adjustment range Factory setting
drC- [MOTOR CONTROL] (continued)
SPG
[Speed prop. gain]
0 to 1,000% 40%
g
T
Speed loop proportional gain.
Visible if [Motor control type] (Ctt) is not set to [Standard] (Std), [V/F 5pts] (UFS) or [V/F Quad.] (UFq).
SPGU
[UF inertia comp.]
0 to 1,000% 40%
g
T
Inertia factor for following motor control laws.
Visible if [Motor control type] (Ctt) is set to [Standard] (Std), [V/F 5pts] (UFS) or [V/F Quad.] (UFq).
SIt
[Speed time integral]
1 to 65,535 ms 63 ms
g
T
Speed loop integral time constant.
Visible if [Motor control type] (Ctt) is not set to [Standard] (Std), [V/F 5pts] (UFS) or [V/F Quad.] (UFq).
SFC
[K speed loop filter]
0 to 100 65
g
T
Speed filter coefficient (0(IP) to 100(PI)).
FFH
[Spd est. filter time]
0 to 100 ms 6.4 ms
g
Accessible in Expert mode only.
Frequency to filter the estimated speed.
CrtF
[Cur. ref. filter time]
0 to 100 ms 3.2 ms
g
Accessible in Expert mode only.
Filter time of the current reference filter [of control law (if [No] (nO): stator natural frequency)].
UFr
[IR compensation]
0 to 200% 100%
T
Used to optimize torque at very low speed, or to adapt to special cases (for example: for motors connected in parallel, decrease
[IR compensation] (UFr)). If there is insufficient torque at low speed, increase [IR compensation] (UF r). A too high value
can avoid the motor to start (locking) or change the current limiting mode.
SLP [Slip compensation]
0 to 300% 100%
g
T
This parameter cannot be accessed if [Motor control type] (Ctt) is set to [Sync. mot.] (SYn).
This parameter is written at 0% when [Motor control type] (Ctt) is set to [V/F Quad.] (UFq).
Adjusts the slip compensation around the value set by the rated motor speed.
The speeds given on motor nameplates are not necessarily exact.
If slip setting is lower than 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 higher than actual slip: The motor is overcompensated and the speed is unstable.
U1 [U1]
0 to 800 V according to rating 0 V
g
V/F profile setting.
This parameter can be accessed if [Motor control type] (Ctt) is set to [V/F 5pts] (UF5).
F1 [F1]
0 to 599 Hz 0 Hz
g
V/F profile setting.
This parameter can be accessed if [Motor control type] (Ctt) is set to [V/F 5pts] (UF5).
U2 [U2]
0 to 800 V according to rating 0 V
g
V/F profile setting.
This parameter can be accessed if [Motor control type] (Ctt) is set to [V/F 5pts] (UF5).
F2 [F2]
0 to 599 Hz 0 Hz
g
V/F profile setting.
This parameter can be accessed if [Motor control type] (Ctt) is set to [V/F 5pts] (UF5).
