System Messages - Alphabetical List *E-STOP from user enable switch* (-912) Explanation: An E-STOP condition has occurred because the user enable switch (formerly called the Hold-to-Run switch) has been released. During MANUAL mode, releasing this switch performs a controlled power-off rather than an E-STOP. User action: Hold the user enable switch and re-enable HIGH POWER as desired. If the switch was already pressed, check the switch and the associated connectors and wiring. *E-STOP from user E-STOP button* (910) Explanation: An E-STOP condition has occurred because the user E-STOP button circuit has been broken. User action: Restore the user E-STOP button circuit.
Re-enable HIGH POWER as desired. *E-STOP from user muted safety gate* (-921) Explanation: An E-STOP condition has occurred because the user muted safety gate has been opened during automatic mode. During MANUAL mode, this error should not be seen. User action: Close the muted safety gate and re-enable HIGH POWER as desired. If the gate was already closed, check the switch, the associated connectors, and wiring. *E-STOP unstable* (-939) Explanation: The E-STOP source has not been resolved. User action: Check if there is noise on the E_STOP line. Executing in DRY.RUN mode (50) Explanation: The DRY.RUN switch is enabled and program execution has been requested.
Thus, no motion of the robot occurs. User action: None unless motion of the robot is desired. In that case, abort execution of the program and disable the DRY.RUN switch. *Expected servo node not found* (-679) Explanation: After a servo bus reset, eV+ has not detected all the required nodes on the servo network. Either the network has failed because of noise, a servo node has failed, or a servo node has been unplugged. User action: Use the SRV.NET command to determine which node is causing this error. Verify that all servo network connectors are secure. Reinitialize your servo network. Reboot your robot controller. If the problem persists, contact Omron Adept Customer Service.
