6–8: Reserved
Note: Setting mode 1–8, 100% corresponds
to three times of the motor current.
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 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 coefficient. The bigger the weakening
control coefficient is, the steeper the weak
curve is.
Setting range of P03.22: 0.1–2.0
Setting range of P03.23: 10%–100%
P03.24 set the Max. Voltage of the inverter,
which is dependent on the site situation.
Setting range: 0.0–120.0%
