1-56 U/f Characteristic - F
Range:
Function:
0 Hz*
[0 - 1000.0 Hz]
Enter the frequency points to manually form a U/f-characteristic matching the motor.
The voltage at each point is defined in par.1-55
.
This parameter is an array parameter [0-5] and is only accessible when par. 1-01

2.3.6 1-6* Load Depend. Setting
Parameters for adjusting the load-dependent motor settings.
1-60 Low Speed Load Compensation
Range:
Function:
100 %*
[0 - 300 %]
Enter the % value to compensate voltage in relation to load when the motor is running at low speed
and obtain the optimum U/f characteristic. The motor size determines the frequency range within
which this parameter is active.
