Torque limit when operating on a SINAMICS S120 with field weakening
The SINAMICS S120 converter injects a field weakening current, which means that the
motor can operate above the voltage limiting characteristic. The method used by the
converter to inject the field weakening current has a significant influence on the curve
characteristic.
The characteristics shown apply to operation on a SINAMICS S120 converter.
Field weakening operation is always active for a SINAMICS S120 converter.
The shape of the characteristics in field weakening mode depends on the position of the
voltage limiting characteristic. Therefore, an appropriate torque-speed characteristic is
assigned in the field-weakening range for each converter output voltage.
