Abstract
PURPOSE: To prevent machinery from vibrations by controlling the driving speed and phase angle lags of plural vibrating machines to kill vibrating directions of these machines with each other.
CONSTITUTION: In a frequency and phase controller connected to vibrating machines M1 and M2 respectively through a servo unit, the driving speed (revolution speed) for these machines is set by frequency, and the phase angle lag is separately set for each machine. When these settings are given, the frequency and phase controller and the servo unit are worked to maintain the set driving speed and phase angle lags. The output by a vibrometer provided at a vibration-preventing point is stored in a storage circuit, and a command signal is output from a command program circuit in an integrated command unit for changing displacement values of the driving speed and the phase angles properly to reduce vibration.
