VD120 Series Inverter User Manual Parameter Description

F3-16
Torque Adjustment
Integral Gain
0~60000 1300
○
Vector control current loop PI regulation parameter, the parameter will automatically receive after in
the asynchronous motor complete tuning, generally do not need to be modified.
What need reminds is, current loop integral controller, integration time is not used as the dimension,
but directly setting the integral gain. Current loop PI gain setting is too big, may lead to the control
loops oscillation, so when the current oscillation or torque fluctuation change greatly, can be manually
reduce the PI proportional gain and integral gain here.
F3-17
Speed Loop Integral
Separation Enable
0: Disabled
1: Enabled
0
○
To prevent the overregulation, generally do not need to adjust.
F3-20
Max Weak Magnetic
Current
1%~300% 50%
○
F3-21
Weak Magnetic
Automatic Gain
Adjustment
10%~500% 100%
○
F3-22
Weak Magnetic Integral
Multiples
2~10 2
○
Change the F3-21 and F3-22 can change the adjustment speed of weak magnetic current, but weak
magnetic current adjust faster could lead to instability, generally do not need to manually modify.
F3-23 Torque Boost Coefficient 0.0%~60.0% 10.0%
○
F3-24
Torque Boost Cutoff
Frequency
0.00Hz~max frequency 20.00
○
In order to compensate the speed vector control low frequency torque characteristics, inverter output
voltage do some compensation when low frequency. But torque boost set is too large, motor easy to
overheat, inverter is easy to overcurrent.
When the load is heavier and motor starting torque is not enough, suggest increase this parameter,
can reduce the torque when the load is lighter.
F3-25
Exciting Current
Compensation Gain
0~500 0
○
F3-26
Torque Current
Compensation Gain
0~500 0
○
F3-27 Torque Response Gain 1~1000 10
○
For the excitation current and torque current compensation of electricity blows quantitative
component in the vector control, generally do not need to be adjusted.
