In addition, an independent speed setpoint exists for setting the speed at which rated voltage
is achieved can be used for motors that have the duty cycle to allow for increased flux at lower
speeds than rated. Once the motor voltage is achieved, it is held at this point for higher speeds
at reduced flux.
This feature is set by the parameter "Speed at rated volts" (ID 3145), and can be used with or
without the Adjustable Flux Demand table – provided the table is set up properly. Essentially, this
feature sets the point at which field weakening begins.
