Code 201330: <location>Topology: Quick commissioning not possible

Issue Description & Safety Warning

The Siemens SINUMERIK 840D CNC has triggered a critical <location>Topology: Quick commissioning not possible 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

Message value: Fault cause: %1, supplementary informat ion: %2, preliminary component number: %3 Drive object: All objects Reaction: NONE Acknowledge: NONE Cause: Unable to carry out a quick commissioning. The exis ting actual topology does not fulfill the requirements. Alarm value (r2124, interpret hexadecimal): ccccbbaa hex: cccc = preliminary component number, bb = supplementary information, aa = fault cause aa = 01 hex = 1 dec: On one component illegal connections were detected. - bb = 01 hex = 1 dec: For a Motor Module, more than one motor with DRIVE-CLiQ was detected. - bb = 02 hex = 2 dec: For a motor with DRIVE-CLiQ, the DRIVE-CLiQ cable is not connected to a Motor Module. aa = 02 hex = 2 dec: The topology contains too many components of a particular type. - bb = 01 hex = 1 dec: There is more than one master Control Unit. - bb = 02 hex = 2 dec: There is more than 1 inf eed (8 for a parallel circuit configuration). - bb = 03 hex = 3 dec: There are more than 10 Motor M odules (8 for a parallel circuit configuration). - bb = 04 hex = 4 dec: There are more than 9 encoders. - bb = 05 hex = 5 dec: There are more than 8 Terminal Modules. - bb = 07 hex = 7 dec: Unknown component type - bb = 08 hex = 8 dec: There are more than 6 drive slaves. - bb = 09 hex = 9 dec: Connection of a drive slave not permitted. - bb = 0a hex = 10 dec: There is no drive master. - bb = 0b hex = 11 dec: There is more than one motor with DRIVE-CLiQ for a parallel circuit. - cccc: Not used. SINAMICS-Alarms aa = 03 hex = 3 dec: More than 16 components are connected at a DRIVE-CLiQ socket of the Control Unit. - bb = 0, 1, 2, 3 means e.g. detected at the DRIVE-CLiQ socket X100, X101, X102, X103. - cccc: Not used. aa = 04 hex = 4 dec: The number of components connected one after the other is greater than 125. - bb: Not used. - cccc = preliminary component number of the first component and component that resulted in the fault. aa = 05 hex = 5 dec: The component is not permissible for SERVO. - bb = 01 hex = 1 dec: SINAMICS G available. - bb = 02 hex = 2 dec: Chassis available. - cccc = preliminary component number of the first component and component that resulted in the fault. aa = 06 hex = 6 dec: On one component illegal EEPROM data was detected. These must be corrected before the system continues to boot. - bb = 01 hex = 1 dec: The Order No. [MLFB] of th e power unit that was replaced includes a space retainer. The space retainer (*) must be replaced by a correct character. - cccc = preliminary component number of the component with illegal EEPROM data. aa = 07 hex = 7 dec: The actual topology contains an illegal combination of components. - bb = 01 hex = 1 dec: Active Line M odule (ALM) and Basic Line Module (BLM). - bb = 02 hex = 2 dec: Active Line M odule (ALM) and Smart Line Module (SLM). - bb = 03 hex = 3 dec: SIMOTION control (e.g. SIMOTION D445) and SINUMERIK component (e.g. NX15). - bb = 04 hex = 4 dec: SINUMERIK control (e.g. SINUMERIK 730.net) and SIMOTION component (e.g. CX32). - cccc: Not used. Note: Connection type and connection number are described in F01375. See also: p0097 (Select drive object type), r0098 (Actual device topology), p0099 (Device target topology) Remedy: - adapt the output topology to the permissible requirements. - carry out commissioning using the commissioning software. - for motors with DRIVE-CLiQ, connect the power and DRIVE-CLiQ cable to the same Motor Module (Single Motor Module: DRIVE-CLiQ at X202, Doubl e Motor Module: DRIVE-CLiQ from motor 1 (X1) to X202, from motor 2 (X2) to X203). Re aa = 06 hex = 6 dec and bb = 01 hex = 1 dec: Correct the order number when commissi oning using the commissioning software.
