NEED HELP, Siemens 840D Alarms 25100 & 26020 I have been facing the same issue with these alarms. The alarms generally occur on X2,Z2,Z3. I can get the alarm to go away sometimes. In order to do this I jump the Axis brake with 24v and physically move the axis. This usually will help but is only a temporary fix. The machine will then stay on until a restart is forced. Almost every time the machine is shut down these alarms will occur. X2 will pop up and then go away with a simple machine restart. Currently Z2 and Z3 have faulted. I jumped Z3 and moved it and it is gone. Z2 however will not go away. I am going to try to clean the scale and checked the cables. They problem seems to be farther back maybe with the profibus. I am not sure if it is a voltage issue. Any help would be greatly appreciated. ------------------------------------------------------------------------------------------ |
