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.
P03.22 is only valid for vector control mode 1.
The setting range of P03.22: 0.1~2.0
The setting range of P03.23: 10%~100%
P03.24
Max. voltage limit
P03.24 sets the maximum voltage of the inverter,
which is dependent on the site situation.
The setting range: 0.0~120.0%

Pre-exciting time
Carry out motor pre-excitation when the inverter
starts up. Build up a magnetic field inside the inverter
to improve the torque performance during the
starting process.
The setting range: 0.000~10.000s
