Parameter 14-51 DC-link Compensation

14-51 DC-link Compensation
Default value: [1] On
Parameter type: Option
Setup: All setups
Conversion index: -
Data type: Uint8
Change during operation: True
The rectified AC-DC voltage in the DC link of the drive is associated with voltage ripples. These ripples can increase in magnitude
with increased load. These ripples are undesirable because they can generate current and torque ripples. A compensation method
is used to reduce these voltage ripples in the DC link. In general, DC-link compensation is recommended for most applications, but
pay attention when operating in field weakening as it can generate speed oscillations at the motor shaft. In field weakening, turn off
DC-link compensation.
