Embodiment Construction
[0026] The specific implementation manner of the present invention will be described below in conjunction with the accompanying drawings.
[0027] The present invention provides a protection method for tool retraction of a numerically controlled machine tool. On the basis of its original functions such as speed control, torque control, and bus control, a tool retraction protection function is added to ensure the integrity of the servo drive device and the safety of the entire machine tool system. .
[0028] The tool retract protection function mainly includes trigger source setting and response mode setting. Such as figure 1 As mentioned above, when the system is running, that is, the CNC machine tool is in normal operation, the power supply 1 (380V AC) is input to the power module 2, and the power module 2 is rectified to form a DC bus 3, and the DC bus 3 is connected to the servo drive device 6, and the CNC system 4 passes through The bus 5 is connected to the servo drive ...
