Title:
DEVICE FOR CONTROLLING DRIVE OF MOLD OSCILLATION
Document Type and Number:
Japanese Patent JP3026173
Kind Code:
B2
Abstract:

PROBLEM TO BE SOLVED: To provide a driving control device which can sufficiently restrain oscillation characteristic in a resonance system and can stably work a mold oscillation device in a desired operation waveform.
SOLUTION: In a control device 60 according to a command signal SC from an input signal generator (show no figure), the servo motor command arithmetic means 64 inputs quantity Xm of mold state arithmetically outputted based on a mold positional signal SM from a positional sensor 46 with a mold positional arithmetic means 61, quantity Xr of rod state arithmetically outputted based on a rod positional signal SL from a positional sensor 47 with a rod positional arithmetic means 63 and quantity Xs of spool state arithmetically outputted based on a revolutional number signal SR from a revolutional number signal 48 with a spool positional arithmetic means 67, and a servo motor revolutional speed command is calculated and outputted to a servo amplifier 50. Then, the servo amplifier 50 supplies the driving current to the servo motor 43 according to the servo motor revolutional speed command and the revolutional number signal SR.
