Parameter
number:
152 Unit: Hz
Data type: uint16 Access type: Read/Write
P 4.4.4.13 VT Level
Enter the level of motor magnetization at low speed. Selecting a low value reduces energy loss in the motor but also reduces load
capability.
Default value: 66 Parameter type: Range (40–90)
Parameter
number:
1440 Unit: %
Data type: uint8 Access type: Read/Write
NOTICE
This parameter is not active when P 4.2.1.1 Motor Type is set to options that enable PM motor mode.
P 4.4.4.14 Min. Current at Low Speed
Enter the minimum motor current at low speed. Increasing this current improves motor torque at low speed. The parameter is only
enabled for PM motors.
Default value: Size Related Parameter type: Range (Size Related)
Parameter
number:
166 Unit: %
Data type: uint32 Access type: Read/Write
7.5.3.5 Dead Time Compensation (Menu Index 4.4.4.5)
P 4.4.5.1 Dead Time Compensation Level
Level of applied dead time compensation in percentage. A high level (>90%) optimizes the dynamic motor response, a level from 50–
90% good for both motor-torque ripple minimization and the motor dynamics, a zero level turns off the dead time compensation.
Default value: Size Related Parameter type: Range (0–100)
Parameter
number:
1407 Unit: –
Data type: uint8 Access type: Read/Write
P 4.4.5.2 Dead Time Bias Current Level
Set a bias signal (in [%]) to add to the current-sense signal for dead time compensation.
Default value: Size Related Parameter type: Range (0–100)
Parameter
number:
1409 Unit: %
Data type: uint8 Access type: Read/Write
