Siemens CNC servo maintenance includes ：802C S、802D SL、810D DE、820D SL、840C CE、840D DE、840D SL、840Di SL、S120 NC circuit board 、 CNC servo drive module 、 Control module 、 Power module, etc .

Fault analysis and detection and fault hardware replacement , According to the fault alarm and working performance of Siemens frequency converter, preliminarily judge the type of fault and which hardware has problems , Then narrow the detection range according to the preliminary judgment , Accurately find the faulty hardware through troubleshooting and replacement of new accessories . During the maintenance process, you need to be familiar with the structure and components of Siemens frequency converter , At the same time, maintenance engineers need to detect and eliminate .

Common faults ： No display 、 Call the police 、 Lack of phase (lf)、 Over current （oc）、 Overvoltage (ov)、 Undervoltage (lv)(uv)、 Overheated (oh)、 overload (ol)、 Grounding (gf)、 Load short circuit （sc）、 Parameter error 、 Yes display no output 、 The module is damaged 、 The inverter wiring is damaged 、 The power supply of frequency converter is abnormal 、 Slow speed and other common fault phenomena in frequency converter maintenance . There are many practical reasons for the above frequency converter faults, which need to be analyzed in detail .

Power drive board 、 Main control board of frequency converter 、IGBT modular 、 Filter capacitor and other capacitors and resistors . It is possible that a single hardware module is damaged , Sometimes several modules fail at the same time , This requires accurate detection and troubleshooting of maintenance engineering .
