The function code is used to set the limit of the
torque.
Setting range: 0.0–300.0% (motor rated current)
The usage of motor in flux weakening control.
Function code P03.22 and P03.23 are effective
at constant power. The motor will enter the flux
weakening state when running at rated speed.
Change the flux weakening curve by modifying
the flux weakening control coefficient. The bigger
the flux weakening control coefficient is, the
steeper the weakening curve is.

Setting range of P03.22: 0.1–2.0
Setting range of P03.23: 10%–100%
This parameter sets the max. voltage of the VFD,
which is dependent on the site situation.
Setting range: 0.0–120.0%
Pre-activate the motor when the VFD starts up.
Build up a magnetic field inside the motor to
improve the torque performance during the
starting process.
