On-line diagnosis and off-line diagnosis...
1. Online diagnosis
The on-line diagnosis of CNC lathes in Dalian refers to the control programs of the CNC system. In the normal operating state of the CNC system, the CNC system automatically controls the input/output of the CNC controller, PLC controller, servo system, PLC, and other external components connected to the CNC. Installation stops automatic testing, inspections, and displays status information and fault information. In addition to the alarm number and alarm content on the screen, the system displays the state of the NC internal marker register and the PLC operation unit in real time, providing great convenience for fault diagnosis.
2. Offline diagnosis
When the numerical control system's numerical control system is faulty or if it is necessary to determine whether it is an ancient fault, it is often necessary to suspend processing and stop the inspection. This is the off-line diagnosis. The day of off-line diagnosis is to repair the system and fault location. It tries to locate the problem in the smallest possible range, such as to a certain area or a module.
During the dry period, the CNC installation adopts diagnostic tape to stop the offline diagnosis of the CNC system. The diagnostic tape provides the data required for diagnosis. During diagnosis, the contents of the diagnostic paper tape are read into the RAM in the CNC installation. The micro processor in the system stops analyzing according to the corresponding output data to determine whether the system is faulty and confirms the fault location. The recent CNC system employs engineers. Panel, modified CNC system or special test installation stop test.
