Dead Time Compensation (Menu Index 4.4.4.5) - Danfoss iC2 Application Manual

Application Guide | iC2-Micro Frequency Converters
Parameter
152
number:
Data type:
uint16
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
1440
number:
Data type:
uint8
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.

Dead Time Compensation (Menu Index 4.4.4.5)

7.5.3.5
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.
