Official Troubleshooting Steps
Message value: Fault cause: %1, supplementary informati on: %2, preliminary parameter number: %3 Drive object: All objects Reaction: NONE Acknowledge: IMMEDIATELY Cause: The macro cannot be executed. Fault value (r0949, interpret hexadecimal): ccccbbaa hex: cccc = preliminary parameter number, bb = supp lementary information, aa = fault cause Fault causes for the trigger parameter itself: -20: Called file is not valid for parameter 15. -21: Called file is not valid for parameter 700. -22: Called file is not valid for parameter 1000. -23: Called file is not valid for parameter 1500. -24: Data type of a TAG is incorrect (e.g.: Index, number or bit is not U16). Fault causes for the parameters to be set: -25: Error level has an undefined value. -26: Mode has an undefined value. -27: A value was entered as string in the tag value that is not "DEFAULT". -31: Entered drive object type unknown. SINAMICS-Alarms -32: A device was not able to be found for the determined drive object number. -34: A trigger parameter was recursively called. -35: It is not permissible to write to the parameter via macro. -36: Check, writing to a parameter unsuccessful, parameter can only be read, not available, incorrect data type, value range or assignment incorrect. -37: Source parameter for a BICO in terconnection was not able to be determined. -38: An index was set for a non-indexed (or CDS-dependent) parameter. -39: No index was set for an indexed parameter. -41: A bit operation is only permissible for para meters with the parameter format DISPLAY_BIN. -42: A value not equal to 0 or 1 was set for a BitOperation. -43: Reading the parameter to be changed by the BitOperation was unsuccessful. -51: Factory setting for DEVICE may only be executed on the DEVICE. -61: The setting of a value was unsuccessful. Remedy: - check the parameter involved. - check the macro file and BICO interconnection. See also: p0015, p0700, p1000, p1500
