Detailed instruction of parameters
Torque boost is used for the compensation of low frequency
torque. P04.01 is relative to the Max. output voltage V
P04.02 defines the percentage of closing frequency of
manual torque referred to f
Torque boost should be selected according to the load. The
bigger the load is, the bigger the torque is. Too big torque
boost is inappropriate because the motor will run with over
magnetic, and the current of the inverter will increase to add
the temperature of the inverter and decrease the efficiency.
When the torque boost is set to 0.0%, the inverter is
automatic torque boost.
Torque boost threshold: below this frequency point, the
torque boost is effective, but over this frequency point, the
torque boost is invalid.
The setting range of P04.01:0.0%: (automatic) 0.1%~10.0%
The setting range of P04.02: 0.0%~50.0%
When P04.00 =1, the user can set V/F curve through
P04.03~P04.08.
V/F is generally set according to the load of the motor.
Note:V1＜V2＜V3, f1＜f2＜f3. Too high low frequency
voltage will heat the motor excessively or damage.
Overcurrent stall or overcurrent protection may occur.
The setting range of P04.03: 0.00Hz~P04.05
The setting range of P04.04: 0.0%~110.0%
The setting range of P04.05: P04.03~ P04.07
The setting range of P04.06: 0.0%~110.0%
(the rated voltage of motor 1)
The setting range of P04.07: P04.05~ P02.02
(the rated frequency of motor 1)
The setting range of P04.08: 0.0%~110.0%
(the rated voltage of motor 1)
