Title:
SETTING DEVICE
Document Type and Number:
Japanese Patent JPS61220002
Kind Code:
A
Abstract:
PURPOSE:To make a troublesome procedure at the time of switching an operation place unnecessary by sampling outputs of plural setting devices by the prescribed period so as to calculate a change amount signal and forming a reference value based on said signal. CONSTITUTION:Casting speed setting devices 1 and 2 divide the prescribed voltages and output speed setting signals S1 and S2. Receiving said signals, change amount detectors 3 and 4 sample the signals S1 and S2 by the prescribed period, calculate a deviation between the previous sample value and the current one and output it as change amount signals S3 and S4 until the next sample time. An operation place switching device 5 selects either one of the signals S3 and S4 and applies it to an integrator 6. It integrates the selected change amount signal and applies it as a reference signal S6 to a speed controller 14. Thus the troublesome procedure at the time of switching the operation place can be unnecessary.
