"3-phase PMAC motor (sinewave)" advanced settings
When you click on the
Advanced Settings
button (see
Figure 16
), the
Advanced Settings
dialog box opens (see
Figure 17
). This is where the advanced "3-phase PMAC motor
(sinewave)" motor type parameters are set.

"3-phase PMAC motor (sinewave)" advanced parameters
Parameters name
Description
Switches PWM
frequency
Pulse width modulation (PWM) frequency in kHz.
Dead times value
Selects from the available preset the dead time duration values in microseconds (µs).
Ph/F curve
The software uses this curve to set the value of the phase shift based on the actual value of the
rotor frequency when the "set phase shift according to Ph/F curve" option is set in the main
window. The curve is a linear interpolation between two knee-points.
First knee-point
Phase shift
Sets the phase shift value of the first knee-point of the curve.
Frequency
Sets the frequency value of the first knee-point of the curve.
Second knee-point
Phase shift
Sets the phase shift value of the second knee-point of the curve.
Frequency
Sets the frequency value of the second knee-point of the curve.
Stop condition
Free wheeling
After stopping, the motor continues to spin freely.
Active braking
Motor is braked, generating a stator field 90° in advance with respect to the rotor field.
