Official Troubleshooting Steps
Parameters: %1 = Channel number %2 = Axis number %3 = Error ID and gantry unit. Definitions: Error ID and gantry unit - 30XX => Gantry group cannot be closed, as not all gantry axes are in one channel. - 40XX => Gantry group cannot be closed, as the gantry axes have different ax is states, for example the axis is assigned to the PLC. - 50XX => Gantry group is to change channel due to a PLC request, not all gantry axes are known in the new channel. - 60XX => Gantry group is to be transferred to the channel due to an NC program request, but the channel does not know all the gantry axes. Reaction: NC Start disable in this channel. Interface signals are set. Alarm display. NC Stop on alarm. Remedy: Error ID: - 30XX => assign all gantry axes to the current channel, for example via axis exchange. - 40XX => set all axes of the gantry group to the sa me axis state, for exampl e assign all axes to the NC program, or assign all axes to the PLC. - 50XX => make all gantry axes known to the required channel. - 60XX => make all gantry axes known to the required channel.:end Program Continuation: Clear alarm with the RESET key.
