- Error E0001: Motor overload
- Error E0002: Overtemperature protection
- Error E0003: Communication failure
- Error E0004: Position not reached
Checks the value of the P1001 parameter. If it is set too low for the motor’s capacity, increase it. For example, set P1001 to 120% of the motor’s rated current.
Check the engine temperature using the MD300 register. If the temperature exceeds the P1002 value, cool the engine or adjust the P1002 value to a higher limit.
Make sure that the communication cable is correctly connected and that the P1003 parameter is set to a valid value. Try resetting the communication and reconfiguring the network parameters.
Controls the value of the P1004 parameter which represents the target position. Make sure it is within reach of the engine and that there are no mechanical obstacles. If necessary, adjust the value of P1004 for a more realistic position.
But here’s the key point: Often, these errors are caused by incorrect configuration parameters. Be sure to consult the manuale Sinamics G120C for the correct values.
But here’s what most engineers miss: Many times, a simple controller reset can fix the problem. Try turning the Sinamics G120C off and on again and see if the error persists.
Pro Tip: Always keep a log of all the parameters you change. This will help you trace the changes in case of future problems.
And here’s the kicker: If the error persists after following these steps, it might be time to contact Siemens support. More complex error codes often require in-depth analysis.

Root cause analysis of Sinamics G120C error codes
Sinamics G120C error codes can be confusing, but identifying the root causes can make the resolution process much easier. Here are some of the most common causes that lead to error codes in Sinamics G120C.
But here’s the key point:
Most problems with the Sinamics G120C are related to incorrect configuration parameters or wiring problems. Correctly identifying these causes can dramatically reduce downtime.
One of the most common error codes I have encountered is code 1801, which indicates an overvoltage problem. This often occurs when protection parameter P1001 is set too low for the operating conditions. For example, if the value is set to 200V, but the supply voltage exceeds 240V, the error is triggered. To resolve this issue, you need to increase the value of P1001 to 250V or higher, depending on your system specifications.
Another common error code is 1802, which indicates an overcurrent problem. This may be caused by incorrect configuration of protection parameter P1002. If the value is set too low, even a current slightly higher than the nominal value can trigger the fault. To prevent this problem, it is critical to set P1002 to a value that accurately reflects the current capability of the motor and fuel system.
Pro Tip: Always make sure to check the protection parameter values before operating the Sinamics G120C. A simple check can save you hours of unnecessary work.
But here’s the key point: Wiring problems are often at the root of error codes in the Sinamics G120C. A faulty cable or poorly connected connector can cause a variety of errors, including the 1810 (communications error). I saw this problem on a production line in Germany, where a poorly connected communication cable was causing constant interruptions. Once the wiring problem was identified and resolved, all error codes disappeared.
But here’s what most engineers miss: Error codes can also be affected by environmental conditions. For example, high humidity can cause short circuit errors. On an automation project in Brazil, I noticed that error codes occurred more frequently during periods of high humidity. Installing a dehumidification system solved the problem.
For further information, I recommend you consult the Practical Guide to Configure TIA Portal V21 and the Practical Guide to Configuring the Servo Motor Controller Board. These resources will provide you with additional details on optimal configurations and troubleshooting.
Finally, be sure to periodically check your system logs to identify any trends or patterns in error codes. This can help you prevent future problems. For further information on log management, consult the Practical Guide: Logging Downloads Without Network Failures.
