Detailed instruction of parameters
This function code is used to select the electro motion and
braking torque upper-limit setting source selection.
0: Keypad setting upper-limit frequency
(P03.20 sets P03.18, P03.21 sets P03.19)
1: AI1. Inverters≤15kW can be set by the digital potentiometer on
the keypad and AI1 setting is not available for the devices ≥18.5kW.
2: AI2
3: AI3
4: HDI
5: MODBUS communication
Note: setting mode 1~9,100% 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%
Reactivate the motor when the inverter starts up. Build up a
magnetic field inside the inverter to improve the torque
performance during the starting process.
Setting time: 0.000~10.000s
0~8000
Note: P03.24~P03.26 are invalid for vector mode.
