Code 14404: [Channel %1: ] Block %2 illegal parameterization of transformation
Issue Description & Safety Warning
The Siemens SINUMERIK 840D CNC has triggered a critical [Channel %1: ] Block %2 illegal parameterization of transformation 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: Error has occurred when selecting transformation. Possible causes of error: - An axis traversed by the transformation has not been enabled: - is being used by another channel (-> enable) - is in spindle mode (-> enable with SPOS) - is in POSA mode (-> enable with WAITP) - is concurrent Pos axis (-> enable with WAITP) - Parameterization via machine data has an error - Axis or geometry axis assignment to the transformation has an error, - Machine data has an error (-> modify machine data, restart) Please note: Any axes not enabled might be signal ed via alarm 14092 or alarm 1011 instead of alarm 14404. Transformation-dependent error causes can be in: TRAORI: TRANSMIT: - The current machine axis position is unsuitable fo r selection (e.g. selection in the pole) (-> change position slightly). - Parameterization via machine data has an error. - Special requirement with respect to the machine ax is has not been fulfilled (e.g. rotary axis is not a modulo axis) (-> modify machine data, restart). TRACYL: The programmed parameter is not allowed when transformation is selected. TRAANG: - The programmed parameter is not allowed when transformation is selected. - Parameterization via machine data has an error. - Parameter is faulty (e.g. TRAANG: unfavorabl e angle value (-> modify machine data, restart) Persistent transformation: - Machine data for persistent transformation ar e wrong (-> consider dependencies, change machine data, restart) Only with active "OEM tr ansformation" compile cycle: The axes included in the transformation must be referenced. Reaction: Correction block is reorganized. Interface signals are set. Alarm display. Remedy: Please inform the authorized personnel/service depar tment. Modify part program or machine data. Only with active "OEM tr ansformation" compile cycle: Reference the axes included in the transfo rmation before selecting transformation. Program Continuation: Clear alarm with NC ST ART or RESET key and continue the program.
