    Sinumerik 810D LED LED showing fault SF and PF .

    I have a Anderson 2004 Omnitech Selexx Pal with the Siemens 810d Controllers that I am in the process of relocating and recommissioning a and could use some assistance.Currently I have the follow LED showing fault SF and PF. Would like some feedback on possible cause..

    The SF is a segment fault on profibus, and the PF is a power fault however these can be misleading, or at least not descriptive.

    A normal action to ensure that its not a controller fault is to perform a PLC and NCK reset, however this will wipe whatever PLC program and NCK configuration is in there. If you are not the OEM of the machine, you may be in a world of trouble if you attempt this without a working and current backup and the ability to restore it with a PG/PC and MPI cable.

    You mentioned that you relocated the machine. If anything was disassembled, then I would ensure that your power connections are measured and correct, and that your profibus connections are all correct. If you did not place the same profibus cables back on the same terminals, this may result in a problem. In certain topologies, a terminating resistor is required at the end of a bus line or the end of a branch. If these were moved (terminations are not on the same places that they originally were) this can cause this problem.

    Also, check all your estops and wiring of any off board estops you may have. Often these are implemented where an e-stop will put the siemens control into this state.

    PF = program fault
    SF = system fault,

    Left hand bank of leds indicate the NC, right hand leds are PLC. If the plc is in run which it looks to be as numerical display is 6 and +5 and PR (program run) are illuminated, you may just have a hardware mismatch in your hardware config (which can be diagnosed further by hooking up a laptop with s7 and going into hardware diagnostics). Do you have any alarms on hmi? If you have anything like "standard machaine data loaded" or "no connection to NC/plc" then you have suffered data loss or corruption.

    I originally did not have the IR guard light connected. I did connect them and applied correct air pressure to machine . Still no change.

    Check behind hmi panel, what is the pcu type, pcu20, pcu50, mmc102, mmc103? There should be a Siemens sticker indicating type. Hopefully you have a pcu50 with .arc backup on.

    Also check profibus connections, purple cable coming out of the ccu, it will have a red switch with 2 positions, on and off. If the plug has two purple cables, i.e. One going in, one going out then switch needs to be off. If it just has one purple cable going in, it needs to be on. This cable will route around your machine hardware, from ccu to plc i/o hmi, to control panel etc. Make sure switch settings are correct at each place.

    Re: Sinumerik 810D LED LED showing fault SF and PF .

    The CNC has a PC based hmi, that go through a cp 5611 card in a Windows 98 system. I believe I found the original parameters for CNC controller.I would appreciate it if someone could check the following link to see if the parameters are there . I need to verify I have the correct information before I call in a tech if I'm not able to do it myself. I appreciate any instructions to reinstall the parameters to my 810d controller.

    Hi Again, sorry for late response as not been on in a while. I had a look through your files and there are several backups of NC & PLC datas on there in .arc formats route path: (cnc - siemens - sinumerik - mmc103 - DH - arc.dir)

    These are sufficient datas needed for a complete reload. The only thing to watch is how uptodate those datas are, ie if it has had a new encoder, ballscrew , re-alignment etc, grid positions may differ on backup to current if the machine hasn't recently been backed up. Hope this helps.

    Hi,

    I have a similar problem with my CNC machine. The battery was broken and I have at now the 120202 "connection error".

    I have a different color light in my "SIMODRIVE" module (images light.jpg)

    Could you help me to solve this problem?

    Mi model is a Sinumerik 840D attach images with information

    Thanks a lot.

    The SF shows a system fault, and the PF a power fault, this will give you a more clear image about what happened.
    I guess the problem is related to the fact that you changes the machine. Have you ensured that all the cabled are connected? It`s always important to put the same cables in exactly same terminals, otherwise it could turn into a lag. Check the cables and terminations, probably the solutions is easier than you think. I hope the fault is not in the controller, but you can run a PLC reset. Be sure to have the possibility to restore if you make this. Otherwise, maybe one of the cables is broken? Have you checked them? I had a similar situation and the problem was in one cable. Had to order some new ones on https://www.litelume.com/
