Sinamics S120 Fault Codes and Alarms, Part I

There are several differences between faults and alarms on Sinamics S120 Drives. Check out our website for all of our Siemens products.

TypeDescription
FaultsWhat happens when a fault occurs?
- The appropriate fault reaction is initiated
- Status signal ZSW1.3 is set.
- The fault is entered in the fault buffer.

How are faults eliminated?
- Remove the original cause of the fault
- Acknowledge the fault
AlarmsWhat happens when an alarm occurs?
- Status signal ZSW1.7 is set.
- Alarms are "Self Acknowledging" meaning they are reset when the cause of the alarm has been eliminated.

List of Sinamics S120 Faults and Alarms

F01000:  Internal software error
Message Value: Module: %1, Line: %2
Drive Object: All Objects
Reaction: OFF2
Acknowledge: POWER ON
Cause: An internal software error has occurred. Fault value (r0949, interpret hexadecimal)
Remedy: Evaluate fault buffer.
Carry out a POWER ON (power on/off) for all components.
If required, check the data on the non-volatile memory (memory card).
Upgrade firmware to a later version.
Replace the control unit or contact MRO Electric.

F01001:  Floating Point Exception
Message Value: %1
Drive Object: All objects
Reaction: OFF2
Acknowledge: POWER ON
Cause: An exception occurred during an operation with the FloatingPoint data type. The error may be caused by the basic system or the OA application (e.g. FBLOCKS, DCC).
Remedy: Carry out a POWER ON (power on/off) for all components.
Check configuration and signals of the blocks in FBLOCKS.
Check configuration and signals of DCC charts.
Upgrade firmware to a later version.
Contact Service Hotline.

F01002:  Internal software error
Message Value: %1
Drive Object: All objects
Reaction: OFF2
Acknowledge: IMMEDIATELY
Cause: An internal software error has occurred
Remedy: Carry out a POWER ON (power on/off) for all components.
Upgrade firmware to a later version.
Contact Service Hotline.

F01003:  Acknowledgement delay when accessing the memory
Message Value: %1
Drive Object: All objects
Reaction: OFF2
Acknowledge: IMMEDIATELY
Cause: A memory area was accessed that does not return a “READY”.
Remedy: Carry out a POWER ON (power on/off) for all components.
Contact Service Hotline

N01004 (F, A):  Internal software error
Message Value: %1
Drive Object: All objects
Reaction: NONE
Acknowledge: NONE
Cause: An internal software error has occurred. 
Remedy:  Read out diagnostics parameter (r9999).
Reaction upon F: OFF2
Acknowl. upon F: POWER ON
Reaction upon A:  NONE
Acknowl. upon A: NONE

F01005:  Firmware  download for DRIVE-CLiQ component unsuccessful
Message Value: Component number: %1, fault cause: %2
Drive Object: All objects
Reaction: NONE
Acknowledge: IMMEDIATELY
Cause: It was not possible to download the firmware to a DRIVE-CLiQ component
Remedy: Check the selected component number
Check the DRIVE-CLiQ connection
Save suitable firmware file for download in “/siemens/sinamics/code/sac/”
Use a component with a suitable hardware version
After POWER ON has been carried out again for the DRIVE-CLiQ component,                               download the firmware again. Depending on p7826, the firmware will be                                       automatically downloaded.

A01006: Firmware update for DRIVE-CLiQ component required
Message Value: Component number: %1
Drive Object: All objects
Reaction: NONE
Acknowledge: NONE
Cause: The firmware of a DRIVE-CLiQ component must be updated as there is no suitable firmware or firmware version in the component for operation with the Control Unit.
Alarm value (r2124, interpret decimal): Component number of the DRIVE-CLiQ component
Remedy: Firmware update using the commissioning software: The firmware version of all of the components on the “Version overview” page can be read in the Project Navigator
under “Configuration” of the associated drive unit and an appropriate firmware update can be carried out.
Firmware update via parameter:
– Take the component number from the alarm value and enter into p7828.
– Start the firmware download with p7829 = 1.

A01007: POWER ON for DRIVE-CLiQ component required
Message Value: Component number: %1
Drive Object: All objects
Reaction: NONE
Acknowledge: NONE
Cause:  A DRIVE-CLiQ component must be powered up again (POWER ON) (e.g. due to a firmware update). Alarm value (r2124, interpret decimal): Component number of the DRIVE-CLiQ component. If the component number is 1, a POWER ON of the Control Unit is required. 
Remedy: Switch off the power supply of the specified DRIVE-CLiQ component and switch it                   on again.
For SINUMERIK, auto commissioning is prevented. In this case, a POWER ON is                           required for all components and the auto commissioning must be restarted.

A01009 (N):   CU: Control module overtemperature
Message Value: –
Drive Object: All objects
Reaction: NONE
Acknowledge: NONE
Cause: The temperature (r0037[0]) of the control module (Control Unit) has exceeded the specified limit value.
Remedy: Check the air intake for the Control Unit.
Check the Control Unit fan.
