Function:
Control the percentage of the magnetizing current. The parameter is active when par. 1-73
Start
is enabled. This parameter is only available in VVC+.
Function:
Control the percentage of the frequency of the test pulses. The parameter is active when
Flying Start
par. 1-73 is enabled. This parameter is only available in VVC+.
Function:
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.

0.25 kW - 7.5 kW
11 kW - 45 kW
55 kW - 550 kW
Function:
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.
