Message value: Parameter: %1, Index: %2, fault cause: %3 Drive object: All objects Reaction: A_INFEED: OFF2 (NONE, OFF1) SERVO: OFF2 (NONE, OFF1, OFF3) VECTOR: OFF2 (NONE, OFF1, OFF3) Acknowledge: IMMEDIATELY Cause: An error was detected when downloading a project using the commissioning software (e.g. incorrect parameter value). For the specified parameter, it was detected that dynamic limits were exceeded that may possibly depend on other parameters. Fault value (r0949, interpret hexadecimal): ccbbaaaa hex aaaa = parameter bb = index cc = fault cause 0: Parameter number illegal. 1: Parameter value cannot be changed. 2: Lower or upper value limit exceeded. 3: Sub-index incorrect. 4: No array, no sub-index. 5: Data type incorrect. 6: Setting not permitted (only resetting). 7: Descriptive element cannot be changed. 9: Descriptive data not available. 11: No master control. 15: No text array available. 17: Task cannot be executed due to operating status. 20: Illegal value. 21: Response too long. 22: Parameter address illegal. 23: Format illegal. 24: Number of values not consistent. 25: Drive object does not exist. 101: Presently de-activated. 104: Illegal value. 107: Write access not permitted when controller enabled. 108: Unit unknown. SINAMICS-Alarms 109: Write access only in the commissioning state, encoder (p0010 = 4). 110: Write access only in the commissioning state, motor (p0010 = 3). 111: Write access only in the commissioning state, power unit (p0010 = 2). 112: Write access only in the quick commissioning mode (p0010 = 1). 113: Write access only in the ready mode (p0010 = 0). 114: Write access only in the commissioning state, parameter reset (p0010 = 30). 115: Write access only in the Safety Integrated commissioning state (p0010 = 95). 116: Write access only in the commissioning st ate, technological application/units (p0010 = 5). 117: Write access only in the commissioning state (p0010 not equal to 0). 118: Write access only in the commissioning state, download (p0010 = 29). 119: Parameter may not be written in download. 120: Write access only in the commissioning stat e, drive basis configuration (device: p0009 = 3). 121: Write access only in the commissioning state, define drive type (device: p0009 = 2). 122: Write access only in the commissioning state, data set basis configuration (device: p0009 = 4). 123: Write access only in the commissioning st ate, device configuration (device: p0009 = 1). 124: Write access only in the commissioning state, device download (device: p0009 = 29). 125: Write access only in the commissioning st ate, device parameter reset (device: p0009 = 30). 126: Write access only in the commissioni ng state, device ready (device: p0009 = 0). 127: Write access only in the commissioning state, device (device: p0009 not equal to 0). 129: Parameter may not be written in download. 130: Transfer of the master control is inhibited via BI: p0806. 131: Required BICO interconnection not possible because BICO output does not supply floating value 132: Free BICO interconnection inhibited via p0922. 133: Access method not defined. 200: Below the valid values. 201: Above the valid values. 202: Cannot be accessed from the Basic Operator Panel (BOP). 203: Cannot be read from the Basic Operator Panel (BOP). 204: Write access not permitted. Remedy: - enter the correct value in the specified parameter. - identify the parameter that restricts the limits of the specified parameter.
