Abstract
A control system for a conveyor system of a machine includes a motor to drive the conveyor system, and a pump operably coupled to the motor. A solenoid actuator actuates the pump. The control system includes operator interfaces to enable an operator to provide inputs indicative of a desired engine speed, and a desired conveyor speed. The control system includes a controller which determines a pump speed based on the desired engine speed, and determines a maximum possible motor speed based on the pump speed and a maximum possible gear ratio between the pump and the motor. The controller determines a desired motor speed based on the desired conveyor speed. The controller determines a solenoid actuation current based on the desired motor speed and the maximum possible motor speed, and supplies the solenoid actuation current to the solenoid actuator to control a speed of the conveyor system.
