Programming Guide
Parameter 14-38 Field Weakening Controller Gain
Table 730: Parameter 14-38 Field Weakening Controller Gain
14-38 Field Weakening Controller Gain
Default value: 20%
Conversion index: 0
Set the integral gain for the field weakening controller.
Parameter 14-39 Torque Change Threshold Limit
Table 731: Parameter 14-39 Torque Change Threshold Limit
14-39 Torque Change Threshold Limit
Default value: 20%
Conversion index: 67
Set the torque change threshold limit in % of the actual torque. When the actual torque exceeds the torque threshold value, the
drive trips within 10 ms.
5.14.5 14-4* Energy Optimizing
Parameters for adjusting the energy optimization level in both variable torque (VT) and automatic energy optimization (AEO) mode
in parameter 1-03 Torque Characteristics.
Parameter 14-40 VT Level
Table 732: Parameter 14-40 VT Level
14-40 VT Level
Default value: 66%
Conversion index: 0
This parameter cannot be adjusted while the motor is running.
This parameter is not active when parameter 1-10 Motor Construction is set to [1] PM non-salient SPM.
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.
Parameter 14-41 AEO Minimum Magnetisation
Table 733: Parameter 14-41 AEO Minimum Magnetisation
14-41 AEO Minimum Magnetisation
Default value: Size related
Conversion index: 0
This parameter is not active when parameter 1-10 Motor Construction is set to [1] PM non-salient SPM.
Enter the minimum allowable magnetization for AEO. Selection of a low value reduces energy loss in the motor but can also reduce
resistance to sudden load changes.
