The Siemens 6SL3040-1MA01-0AA0 is a Sinamics Control Unit CU230-2 PN. It is designed for use with several drives. It is a control central modules in which the closed-loop or open-loop functions are implemented for one or more line modules and/or motor modules. The number for VFD drive depends on the required performance, the required additional functions, and the required operating mode (servo, vector, or U/f). The software and parameters are stored in a plug-in memory card, and the option slot can be used to expand the number of terminals or adapt other communication interfaces to the higher-level control.
If your application requires more than one control unit, the number can be increased accordingly and interconnected via the Profibus. The 6SL3040-1MA01-0AA0 communicates with its associated components, like motor modules, line modules, sensor modules, and terminal modules, via the internal system’s DRIVE-CLiQ interface. The module has 12 isolated digital inputs, and 8 non-isolated digital inputs/outputs.
With the 6SL3040-1MA01-0AA0, an open input is interpreted as “low”, and terminal M1 must be connected so that the digital inputs (DI) can function. This can be completed by either providing the ground reference for the digital inputs, or by using a jumper to terminal M. If at any time the 24V power supply is briefly interrupted, the digital outputs are deactivated. If at any time the memory card is withdrawn or inserted while the 6SL3040-1MA01-0AA0 is in operation, then data can be lost and a plant standstill could occur. Only withdraw the memory card when the control unit is in a no-voltage condition. Electrical fields and electrostatic discharge can also result in the memory card being damaged, so observe ESD regulations when handling it.
There are several differences between faults and alarms on Sinamics S120 Drives.
What 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
What 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) 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.

A blog we posted earlier this week about the Micromaster 420 troubleshooting referenced the Faults and Alarms list for the Micromaster series, so we decided that it would make sense to make the list of Micromaster 420 Faults and Alarms directly available. This is from the corresponding manual for the Micromaster 420 series, but it is buried within the manual which most people most likely don’t even have. Hopefully this helps with your troubleshooting.
Often people have difficulty installing a replacement drive that we send out, and normally it just takes the troubleshooting tips from the manual to get them up and running. However, the manual isn’t always the easiest to find or sort through, so below we’re posting the Siemens Micromaster 420 Troubleshooting section from the manual which should help anyone who is working to get the issues with their drive sorted out. To check out the full list of Siemens Micromaster drives on our site you can visit the link here or email email@example.com
