Alarm 1325: communnication Error

    I am new to Yaskawa Motoman Robots and have tried my hands on Fanuc!


    I am trying to power up a NX100 robot controller with manipulator ES165N. Everything was OK till the


    Alarm 1325: Communication Error
    Robot 1[slurbt] (in all axes)


    came. I checked all the encoder cables and found them OK. Also, i tried to perform Home Position setting under the Management Mode but I could not select the axis (or all the axes using 'edit' button) and SERVO ON LED was blinking and i could not get the servo on even after pressing the deadman. I was wondering if this alarm is equivalent to pulse mismatch in Fanuc??


    Can any one suggest some ways (apart from the ones given in the manual) to overcome these issues .


    Thanks in advance!

    Aishpd,


    The 1325 alarm comes up if the system stops communicating with any encoder. You can have this at two times. One, if the robot is running and the wire to the encoder brakes or is unplugged. The second is during boot up when the system is getting the pulse count from the encoder.


    If all 6 axis are highlighted when you get this alarm, something common is bad. The first thing I would start with is the 1BC cable. If you have another NX robot, all the 1BC cables are the same so you can swap it. The next thing I would check is the 24 volt out to the encoder system. The quickest way is to swap the AXA card with another NX robot (there is no data on AXA card so you can just swap it).


    The next thing would be to call Motoman and see if a service tech could come out and have a look.

    I've had the same alarm. But in a different way. The robot moves fine as long as I keep it at speed override under 30%. If I go faster I get the 1325 alarm. I've changed the 1BC cable and axa board. Didn't help. Any suggestions?

    The CN 07 encoder plug & socket on the AXA servo control board , has separate earth wire for each encoder , check the condition of the plug pins ( you said you have already swapped out the AXA board) .
    I had issues with this plug and found the pins had been damaged from earth faults unknown.
    In your case it could be creating noise, one of the issues associated with fault 1325.

    1325: communication error (maybe the encoders cable inside the cabinet is not properly connected)


    4713: ext 24v power error (maybe the the 24 v line is not wired correctly)


    4107: your robot has lost the home position. Check if the value of the encoder in the home position menu are ok. if someone has a * you have lost the data of that axis and need to rezeroing.


    4109: another dc 24v problem. Should be a subcode whith this error.

    0000_0001 is a fuse blown. 0000_0011 is a power supply error.


    Personally I will contact Yaskawa for help.

    4107: your robot has lost the home position. Check if the value of the encoder in the home position menu are ok. if someone has a * you have lost the data of that axis and need to rezeroing.


    This is incorrect! 4107 means the last known position of the robot is not the same as the current position at startup. This can be from a power outage when the robot was moving, replacing a motor, bad harness, someone unplugging the encoder cable with the power on or the brakes are slipping. Try to confirm the "second Home" position first! do not re-zero your robot! If you have a "*" for abso data do the backup recovery.

    Problem was, that this used robot was connected to the external axis. We didnt know that before, so yaskawa support solved this problem with alarms.

    hiện tại robot Gp25 mà xưởng tôi đang sử dụng, gặp phải lỗi Alarm 1325, tôi có kiểm tra cáp kết nối thấy vẫn bình thường, tôi có tháo cáp ra đặt lại vị trí homposition của 1 động cơ S1, nhưng không được

    sau khi robot bị lỗi Alarm 1325 được 1h lại sẩy ra lỗi Alarm 4312, tôi có kiểm tra điện áp pin vẫn đủ 3.6V. Hiện tại tôi vẫn chưa biết cách sử lý

    Nhờ ace chỉ giúp với ạ

    Có nhiều vị trí pin nhé anh, có thể chỗ anh đo đủ còn chỗ khác thiếu. Hoặc dây có vấn đề ạ.
