TI120 Series Variable Frequency Drive
Detailed parameter introduction
- 90 -
identification, two groups of adjustment parameters are automatically calculated, generally they are not
needed to be modified. If the PI setting of the current loop is too large, the current shall oscillate and the
torque shall fluctuate greatly.
P03.20
Ascending filtering time of
drive torque
rang:0.0s~6000.0s
Factory default:0.3s
P03.21
Declining filtering time of drive
torque
range:0.0s~6000.0s
Factory default:0.3s
In the torque control mode, when the difference between the load torque and the motor output
torque is large, the change rate of the motor output speed is very fast, which may cause excessive
shock to the motor output end. By setting the filtering time of P03.20 and P03.21, the motor output
speed can be changed smoothly and the mechanical shock can be reduced.
P03.22
Torque limitation coefficient in
the weak magnetic area
range:0.0%~200.0%
Factory
default:100.0%
This parameter takes effect only when the motor is running above the rated frequency. When
running in a weak magnetic area, the acceleration time is too long, and the value of P03.22 can be
appropriately reduced.
P03.23
Power limit coefficient in power
generation
range:0.0%~200.0%
Factory
default:100.0%
It is used for limiting the coefficient factor of the output power of the variable frequency drive
working in the power generation status.
P03.24
Torque control deviation
frequency setting
range:0.00Hz~10.00Hz
Factory
default:0.00Hz
Frequency difference of torque current regulator action judgment during torque control
P04 Scalar Control Parameters
P04.00
V/F curve setting
range:0~7
Factory default:0
0: straight line V/F
When running below the rated frequency, the output frequency is linearly related to the output
voltage. It is suitable for general mechanical transmission occasions, such as machine tools, large
inertia fans, centrifuges, etc.
1: multi-stage V/F
The multi-stage V/F curve is generally set by the user according to the motor load characteristics.
The setting function codes include P04.01~P04.08. The variable frequency drive automatically limits the
upper and lower limit of V/F setting value of each point to prevent setting error.
2: 1.2 power
3: 1.4 power
4: 1.6 power
5:1.8 power
