Siemens 808d system is adopted for high-speed CNC drilling and milling machine. Batch debugging steps of this single power head high-speed CNC drilling and milling machine are as follows:

(11) relevant parameters and instructions of spindle debugging

After confirming that the connection of the spindle is correct, the self-learning process is first performed after power on, as follows:

① Unplug T3 terminal to ensure that ST has no signal input. Note: if the T3 motor is not pulled out, the state is wrong after self-learning, and the speed cannot rise

② When the parameter a1.10 (DN) = 7, the driver starts the self-learning mode, and the screen displays Lear, which will last for several minutes

③ When the LED displays f.0, the motor self-learning is completed, and the parameter a1.11 (DN 13) is set to 1, and the motor self-matching parameters

④ Self learning completion
