Abstract
PURPOSE: To ensure an independent control for the open loop control even in case some fault takes place at the feedback control circuit by providing the synchronous type automatic/manual switch.
CONSTITUTION: Synchronous type automatic/manual switch 4 is provided. Automatic/manual switch 2 applies the velocity setting signal given from main controller 1 to comparator 21 to be compared with the velocity feedback signal given from revolution velocity sensor 9 in the automatic mode; while in the manual mode switch 2 applies the necessary velocity setting signal to comparator 21 for comparison with the velocity feedback signal for each series through the manual knob and the operator. Then velocity controller 3 receives the velocity deviation signal of comparator 21 to perform the proportion/integration control function, and the output signal is applied via switch 4 to rake tube controller 5. In this case, if switch 4 selects the output signal in the automatic mode, the output of controller 3 is applied to operating unit 5 in exactly an identical control system to conventional. While in the case of the manual mode of switch 4, the control signal of controller 5 is delivered quite independently from the feedback control to ensure the direct control of the rake tube.
