The Siemens SINUMERIK 840D CNC has triggered a critical [Channel %1: ] Block %2 GEOAX function: incorrect call alarm. Immediate attention from a qualified operator or maintenance technician is required to prevent secondary damage to the equipment or spoiled parts during the manufacturing cycle. Always ensure standard safety and LOTO procedures are followed before accessing electrical cabinets.
Official Troubleshooting Steps
Parameters: %1 = Channel number %2 = Block number, label Definitions: The parameters for calling the GEOAX(...) are incorrect. Possible causes: - Uneven number of parameters. - More than 6 parameters were specified. - A geometry axis number was programmed wh ich was less than 0 or greater than 3. - A geometry axis number was programmed more than once. - An axis identifier was programmed more than once. - An attempt was made to assign a channel axis to a geometry axis which has the same name as one of the channel axes. - An attempt was made to assign a channel axis to a geometry axis lacking IPO functionality (see MD30460 $MA_BASE_FUNCTION_MASK, Bit8). - An attempt was made to remove a geometry axis with the same name as one of the channel axes from the geometry axis grouping. Reaction: Correction block is reorganized. Interface signals are set. Alarm display. Remedy: Modify part program or correction block. Program Continuation: Clear alarm with NC ST ART or RESET key and continue the program.
