Title: Original point resetting system for spindle
Inventor: KOBARI KATSUO
IPC: G05B19/18
Filed: 1987-11-19
Abstract: PURPOSE:To easily reset a spindle to its original point by instructing the distance between a single-revolution signal detecting point and a machine original point to a spindle amplifier from a numerical controller when a specific point of the spindle reaches said signal detecting point. CONSTITUTION:When an original point resetting command is received from a numerical controller CNC 10, a spindle motor 30 is revolved at a constant speed by a spindle amplifier 20 based on the shift command value given from the CNC 10. As a result, a single-revolution signal Pi is detected by a position detector 6 when the spindle 34 is revolved and its specific point reaches a single- revolution signal detecting point. Thus the shift distance P1 between the start of revolution of the spindle 34 and said signal detecting point is informed to the CNC 10. Then the distance P2 between the signal detecting point and a machine original point is added to the distance P1. While the value obtained by subtracting the hitherto commanded shift values from the P1 is outputted from the CNC 10 as the shift command value. As a result, the spindle 34 is positioned by the amplifier 20 and then reset to its original point.
