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%
Parameter type: Range, 10 - 100%
Setup: All setups
Conversion index: 0
Data type: Uint16
Change during operation: True
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%
Parameter type: Range, 10 - 100%
Setup: All setups
Conversion index: 67
Data type: Uint16
Change during operation: True
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%
Parameter type: Range, 40 - 90%
Setup: All setups
Conversion index: 0
Data type: Uint8
Change during operation: False
N O T I C E
This parameter cannot be adjusted while the motor is running.
N O T I C E
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
Parameter type: Range, 30 - 200%
Setup: All setups
Conversion index: 0
Data type: Uint8
Change during operation: True
N O T I C E
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.
