蒂森部分代码（Thyssen part of the code） The local bus and group control bus, the well bus, and the bus connected to the transducer should be tested for looseness or corrosion, and some other plug-ins and wiring should be carefully checked. X3 (local bus), X4 (group control bus), X5 (frequency converter bus), X14, X15 (well path bus) If there is a problem, it could cause a crash, or (-). 6, MN6 brake power supply, power supply board The control voltage of the brake magnet (90V/180VDC) is provided by the MN6 system. In the running of power supply should be measured MN6 X3 output is (90V/180VDC) if the operation error will cause the brake open and closed to normal There is also a possibility of (-). 7, MF3 or 4 in the car If the cars MF3 or 4 interface is not good or bad, it may occur (-) - if the above are no problems, then you can consider Change the board, try it ~ replace this board, do not need to diagnose, change what Dongdong to the same model ~ as long as there are chips, installed on the OK!!! 8, MC2 motherboard problems If the plug-in or motherboard on MC2 if there are any problems also occur (--) - if the above are no problem, but (-) always can not solve the case, recommend the use of diagnostic check on the motherboard of the input and output signals and the fault code analysis to not directly replace the motherboard!!! 9, CPI frequency converter problem If the CPI inverter is overheating or malfunction, it is possible to (-) stop the ladder! In this case, the air conditioner can be cooled by air conditioning, and the control cabinet door is opened to cool down When the CPI inverter is out of order, the emergency stop will also result in the emergence of - - - spot You can check the frequency converter fault with PT ~ and then analyze and confirm the fault!!! Or the speed parameter or other parameter settings of the inverter will also cause a sudden stop, then appear (-), and you need to use PT to determine whether the CPI parameter is correct. 10 encoder failure
