● Synchronous motor, rotary
● Linear motor
● Induction motor
The higher value from the two calculations indicates the maximum motor speed.
HF Drive with VPM
● Synchronous motor
Note
Minimum value of the motor leakage inductance
The motor leakage inductance/armature inductance, including series inductance (L_motor),
must not be less than 2 • p0233. If necessary, this condition must be complied with by using
a suitable series inductance (p0353).
In order to compensate the shift of the filter resonant frequency as a result of the motor, from
a motor leakage inductance/armature inductance of < 3.6 · p0233, an additional capacitance
must be activated in the HF Sine Filter Module (p5174.0 = 1). The default setting for
switching-in the additional capacitance is automatically applied when commissioning the
system for the first time.
The capacitor can also be manually parameterized using parameter p5174.0 (see also
Chapter Overview of important parameters (Page 164)).
● The parameter is activated if the motor leakage inductance is < 3.6 • p0233.
● The parameter is deactivated if the motor leakage inductance is > 3.6 • p0233.
