Function Code Parameter Name Setting Range Default Unit Property
F1-13
Motor auto-tuning current 30–150
60 % ★
It sets the maximum current during synchronous motor auto-tuning.
You need not modify it generally.
Function Code Parameter Name Setting Range Default Unit Property
F1-15
Shaft Q inductance
(torque)
0.00–650.00
3.00 mH ★
F1-16
Shaft D inductance
(excitation)
0.00–650.00
3.00 mH ★
F1-17
Back EMF 0–65535
0 - ★
These parameters are related to the synchronous motor, and obtained by means of motor
auto-tuning.
Function Code Parameter Name Setting Range Default Unit Property
F1-25
Motor type
0: Asynchronous motor
1: Synchronous motor
1 - ★
It is used to set the motor type.
This parameter must be set correctly before motor auto-tuning; otherwise, the motor auto-
tuning cannot be performed.
Group F2: Vector Control Parameters
Function Code Parameter Name Setting Range Default Unit Property
F2-00
Speed loop proportional gain KP1 0–100
40 - ★
F2-01
Speed loop integral time TI1 0.01–10.00
0.60 s ★
F2-02
Switchover frequency 1 0.00 to F2-05
2.00 Hz ★
F2-00 and F2-01 are PI regulation parameters when the running frequency is smaller than
the value of F2-02 (Switchover frequency 1).
Function Code Parameter Name Setting Range Default Unit Property
F2-03
Speed loop proportional gain KP2 1–100
35 - ★
F2-04
Speed loop integral time TI2 0.01–10.00
0.80 s ★
F2-05
Switchover frequency 2 F2-02 to F0-06
5.00 Hz ★
F2-03 and F2-04 are PI regulation parameters when the running frequency is larger than the
value of F2-05 (Switchover frequency 2).
If the running frequency is between F2-02 and F2-05, the speed loop PI parameters are
obtained from the weighted average value of the two groups of PI parameters (F2-00, F2-01
and F2-03, F2-04), as shown in Figure 7-1.
