Min. flux-weakening limit of motor
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 coefficient. The bigger the
weakening control coefficient is, the steeper the
weak curve is.
The setting range of P03.22: 0.10–2.00
The setting range of P03.23: 5%–50%

Pre-exciting time
Preactivate the motor when the VFD starts up. Build
up a magnetic field inside the VFD to improve the
torque performance during the starting process.
