Function
This parameter defines the mutual inductance of the connected motor.
The approximate value of the mutual inductance results from no-load current according to the formula
below:
M
(Vmot
– Rstat*Io) / (2
fmot* Io)

Function
This parameter defines the time constant of the low-pass filter of the bus voltage readout.
Changing this value can avoid motor oscillations, especially when no load is connected to the motor.

Function
This parameter defines the minimum speed of the connected motor. This is the reference speed
forced when the active speed reference is at its minimum value.
NOTE
The value set as the min. speed is used as the saturation of the global reference; the speed
reference will never be lower than the value set as min. speed.

Address
1029
Function
This parameter defines the maximum speed of the connected motor.
This is the reference speed forced when the active speed reference is at its maximum value.
NOTE
According to factory setting, when the equipment is AC power supplied (from optional, auxiliary
AC grid), the motor speed reference is equal to the value in parameter C029.
