Abstract
In some implementations, a controller may monitor, during a ramp up period of a fluid pump driven by a motor that is controlled by a variable frequency drive (VFD), an intake pressure of the fluid pump and a discharge pressure of the fluid pump. The controller may detect, based on monitoring the intake pressure and the discharge pressure, whether the intake pressure satisfies an intake pressure threshold or the discharge pressure satisfies a discharge pressure threshold. The controller may cause, via the VFD, reduction of a torque of the motor based on the intake pressure satisfying the intake pressure threshold or the discharge pressure satisfying the discharge pressure threshold.
