SRVO-105 Door open or E. Stop error R30IA controller

    Hello,

    I am facing with the problem of SRVO-105 . The controller is R30IA with M710IC robot . The controller doesn't have door switch.

    No PLC and no external TBOP connections to panel board or e-stop board (all necessary jumpers are present). The robot was working till esterday.

    When system powered on in auto mode everything seems to be normal, amplifier enabled and robot is ready to work, but after 2-3 minutes (it is random) the srvo-105 error showing up. With reset it is possible to eliminate it , but sometimes it is back immediately and some times after 1-2 minutes show up again. In manual mode the situation is same.

    All recommended steps from trouble shooting manual was done ( panel board , e-stop board, amplifier were replaced , were taken from another working unit). The connectors on E-stop board , panel board and amplifier were checked. The cold start was done.

    Nothing helped, the problem still exist.

    Any suggestions or recommendations ?

    Thank you in advance,

    Approved the thread.

    A few weeks ago I had the same problem with a brand new R-30iB Mate Plus controller. First I also thought about the Estop board or the TP cable. Our controllers are equipped with the TP Disconnect option and therefore, I was able to easily test without the TP (cable) connected. FANUC tech support told me to perform an INIT Start but the error still occured every once a while.

    The robot is connected to a PLC and controlled via the UOP signals. Before starting to randomly change parts, I took a closer look on the UOP signals and there was the problem. When the IMSTP input was set to OFF and then back to ON again before the robot was properly stopped (Prog running, Prog paused, System ready and Cmd enabled = OFF), the SRVO-105 alarm occured instead of the SRVO-037 alarm (which is the correct one when IMSTP is dropped). The same happened with the CSTOPI input. Toggling the signal too fast from OFF to ON and back to OFF again also triggered a SRVO-105 alarm.

    The PLC guy then corrected the program and everything was fine.
