1-61 High Speed Load Compensation
Default value: 100%
Parameter type: Range, 0 - 300%
Setup: All setups
Conversion index: 0
Data type: Int16
Change during operation: True
Enter the % value to compensate voltage in relation to load when the motor is running at high speed and obtain the optimum U/f
characteristic. The motor size determines the frequency range within which this parameter is active.
