Figure 64: Synchronous Motor Start from Zero Speed with DC Start
As an alternative to rotor angle detection for a synchronous motor, it is possible to set the initial position handling as rotor angle parking
by setting parameter 5.6.3.1 Sync. Motor Start Mode to 1 [Rotor angle parking]. This option forces the motor shaft to move to a fixed
position defined by the parameter 5.6.3.5 Sync. Motor Parking Angle Reference, before ramp release.
Synchronous motor start from zero speed with DC-Start and parking is shown in the following illustration.
