Cause: Unable to carry-out a quick commissioning. The existing actual topology does not fulfill the
requirements.
Alarm value (r2124, hexadecimal):
The cause is in byte 1 supplementary information is included in byte 2 and the high word.
Byte 1 = 1:
For a component, illegal connections were detected.
- byte 2 = 1: For a motor module, more than one motor with DRIVE-CLIQ was detected.
- byte 2 = 2: For a motor with DRIVE-CLiQ, the DRIVE-CLiQ cable is not connected to a
motor module.
- high word = preliminary component number of the component with illegal connection.
Byte 1 = 2:
The topology contains too many components of a particular type.
- byte 2 = 1: There is more than one master control unit.
- byte 2 = 2: There is more than 1 infeed (8 for a parallel circuit configuration).
- byte 2 = 3: There are more than 10 motor modules (8 for a parallel circuit configuration).
- byte 2 = 4: There are more than 9 encoders.
- byte 2 = 5: There are more than 8 terminal modules.
- byte 2 = 7: Component type unknown.
- byte 2 = 8: There are more than 6 drive slaves.
- byte 2 = 9: Connection of a drive slave not permitted.
- byte 2 = 10: No drive master available.
- byte 2 = 11: There is more than one motor with DRIVE-CLiQ for a parallel circuit.
- high word = not used.
Byte 1 = 3:
More than 16 components are connected at a DRIVE-CLiQ socket of the control unit.
- byte 2 = 0, 1, 2, 3 means e.g. detected at the DRIVE-CLiQ socket X100, X101, X102,
X103.
- high word = not used.
Byte 1 = 4:
The number of components connected one after the other is greater than 125.
- byte 2 = not used.
- high word = preliminary component number of the 8th component.
Byte 1 = 5:
The component is not permissible for SERVO.
- byte 2 = 1: SINAMICS G available.
- byte 2 = 2: Chassis available.
- high word = preliminary component number of the 1st component found that resulted in
the fault.
Byte 1 = 6:
For a component, illegal EEPROM data was detected. These must be corrected before the
system continues to run-up.
- byte 2 = 1: The Order No. [MLFB] of the power module that was replaced includes a space
retainer. The space retainer (*) must be replaced by a correct character.
- high word = preliminary component number of the component with illegal EEPROM data.
Byte 1 = 7:
The actual topology contains an illegal combination of components.
- byte 2 = 1: Active line module (ALM) and basic line module (BLM).
- byte 2 = 2: Active line module (ALM) and smart line module (SLM).
- byte 2 = 3: SIMOTION control (e.g. D445) and SINUMERIK components (e.g. NX15).
- byte 2 = 4: SINUMERIK control (e.g. NC SINUMERIK 730.net) and SIMOTION
components (e.g. CX32).
- high word = not used.
Note:
Connection type and connection number are described in F01375.
