Tip!
In the Lenze setting, the "linear V/f characteristic" mode is set as motor control. The
parameter settings are preset so that, if the frequency inverter and the 50 Hz
asynchronous machine match in terms of power, the controller is immediately
ready for operation without any further parameter setting expense and the motor
operates satisfactorily.
Recommendations for the following application cases:
• If the frequency inverter and the motor differ widely in terms of power,
set
I
max
) to 2.0 I
N(motor)
.
• If a high starting torque is required
set V
min
) in motor idle state so that the rated motor current (
) flows at a field frequency of f = 3Hz.
• For noise optimisation
set the switching frequency (
to "3" (16 kHz
sin var
).
• If you need a high torque at low speed we recommend the control mode “vector
control".
