Function Parameters
Detailed instruction of parameters
This function code is used to compensate the change of the
rotation speed caused by load during compensation SVPWM
control to improve the rigidity of the motor. It can be set to the
rated slip frequency of the motor which is counted as below:
-n*p/60
△f=f
b
Of which, f
is the rated frequency of the motor, its function
b
code is P02.02; n is the rated rotating speed of the motor
and its function code is P02.03; p is the pole pair of the
motor. 100.0% corresponds to the rated slip frequency△f.
Setting range: 0.0~200.0%
In the SVPWM control mode, current fluctuation may occur
to the motor on some frequency, especially the motor with
big power. The motor can not run stably or overcurrent may
occur. These phenomena can be canceled by adjusting this
parameter.
The setting range of P04.10: 0~100
The setting range of P04.11: 0~100
The setting range of P04.12: 0.00Hz~P00.03
(the Max. frequency)
0: No action
1: Automatic energy-saving operation
Motor on the light load conditions, automatically adjusts the
output voltage to save energy
Select the output setting channel at V/F curve separation.
0: Keypad setting voltage. The output voltage is determined
by P04.28.
1: AI1 setting voltage. Inverters≤15kW can be set by the
digital potentiometer on the keypad and AI1 setting is not
available for the devices ≥ 18.5kW.
2: AI2 setting voltage
3: AI3 setting voltage
4: HDI setting voltage
5: Multi-step speed setting voltage
6: PID setting voltage
7: MODBUS communication setting voltage
Note: 100% corresponds to the rated voltage of the motor.
The function code is the voltage digital set value when the
voltage setting channel is selected as "keypad selection"
The setting range: 0.0%~100.0%
Voltage increasing time is the time when the inverter accelerates
from the output minimum voltage to the output maximum voltage.
Voltage decreasing time is the time when the inverter
decelerates from the output maximum voltage to the output
minimum voltage.
The setting range: 0.0~3600.0s
