14-36 Field-weakening Function
Default value: [0] Auto Parameter type: Option
Setup: All setups Conversion index: –
Data type: Uint8 Change during operation: True
Select the field-weakening function mode in Flux mode.
Option Name Description
[0] Auto The drive calculates the optimal torque
output.
[1] 1/x The drive reduces torque output.
Magnetizing reference is set inversely
proportional to the speed using a static
curve.
14-37 Fieldweakening Speed
Default value: Size related Parameter type: Range (10–60000 RPM)
Setup: All setups Conversion index: 0
Data type: Uint16 Change during operation: True
Enter the start speed for option [1] 1/x in parameter 14-36 Field-weakening Function.
14-38 Field Weakening Controller Gain
Default value: 20% Parameter type: Range (0–100%)
Setup: All setups Conversion index: 0
Data type: Uint16 Change during operation: True
Set the integral gain for field weakening controller.
4.13.5 14-4* Energy Optimising
Parameters for adjusting the energy optimization level in both variable torque (VT) and automatic energy optimization (AEO) mode in
parameter 1-03 Torque Characteristics.
14-40 VT Level
Default value: 66% Parameter type: Range (40%–90%)
Setup: All setups Conversion index: 0
Data type: Uint8 Change during operation: False
Enter the level of motor magnetization at low speed. Selection of a low value reduces energy loss in the motor, but also reduces load
capability.
