Detailed instruction of parameters
The usage of motor in weakening control.
Function code P03.22 and P03.23 are effective at
constant power. The motor will enter into the
weakening state when the motor runs at rated
speed. Change the weakening curve by modifying
the weakening control coefficienct. The bigger the
weakening control coefficienct is, the steeper the
weak curve is.
The setting range of P03.22:0.1~2.0
The setting range of P03.23:10%~100%
P03.24 set the Max. Voltage of the inverter, which is
dependent on the site situation.
The setting range:0.0~120.0%
Preactivate the motor when the inverter starts up.
Build up a magnetic field inside the inverter to
improve the torque performance during the starting
process.
The setting time:0.000~10.000s
0~8000
Note: P03.24~P03.26 are invalid for vector mode.
