SPINDLE POSITION/SPEED CONTROL UNIT |
摘要 |
The invention relates to a spindle speed/position control system for use in a numerically controlled machine tool such as a lathe. To improve the measurement of spindle speed and position, detected elements (12,14) are attached directly to the rotatable spindle (7). A waveform shaping circuit (16) takes the outputs of speed and position detecting sensors (13, 15), and outputs a variety of sinusoidal and pulse signals. The sinusoidally varying signals are employed in speed detection while the pulse signals are used for position detection and control. |
