What to do if Siemens Control Unit displays 'Motor overspeed'?
- KKevin BurchSep 4, 2025
If your Siemens Control Unit displays 'Motor overspeed', activate precontrol of the speed limiting controller (p1401 bit 7 = 1).
What to do if Siemens Control Unit displays 'Motor overspeed'?
If your Siemens Control Unit displays 'Motor overspeed', activate precontrol of the speed limiting controller (p1401 bit 7 = 1).
What to do if Siemens SINAMICS G120D shows 'Power Module overtemperature'?
If your Siemens Media Converter displays a 'Power Module overtemperature' error, verify the ambient temperature is within specified limits, confirm that load conditions and duty cycle are appropriately configured, and check for cooling failures.
What to do if Siemens Control Unit shows 'I2t Motor Module overtemperature'?
If your Siemens Control Unit displays 'I2t Motor Module overtemperature', check and reduce the motor load if necessary. Check the motor's ambient temperature, the thermal time constant p0611, and the overtemperature fault threshold p0605.
How do I resolve 'Motor temperature sensor fault' on Siemens Control Unit?
To resolve a 'Motor temperature sensor fault' on your Siemens Control Unit, ensure that the sensor is correctly connected and check the parameterization (p0601).
What to do for 'Automatic restart aborted' on Siemens Control Unit?
If your Siemens Control Unit shows 'Automatic restart aborted', increase the number of restart attempts (p1211). The current number of start attempts is shown in r1214. Increase the wait time in p1212 and/or monitoring time in p1213. Create ON command (p0840). Increase the monitoring time of the power unit or switch off (p0857). Reduce the wait time for resetting the fault counter p1213 so that fewer faults are registered in the time interval.
How to fix Siemens Control Unit showing 'DC-link voltage undervoltage'?
If your Siemens Control Unit shows a 'DC-link voltage undervoltage' error, check the line voltage (p0210).
How to resolve 'Line phase failure' on Siemens Control Unit?
To address a line phase failure on your Siemens Control Unit, check the converter's input fuses and inspect the motor cables.
Why does my Siemens Control Unit show 'Power Module overtemperature'?
If your Siemens Control Unit displays a 'Power Module overtemperature' message, verify that the ambient temperature is within the defined limits, the load conditions and duty cycle are configured correctly, and that the cooling system is functioning properly.
What should I do if my Siemens Control Unit displays 'Motor blocked'?
If your Siemens Control Unit indicates that the motor is blocked, ensure the motor can rotate freely. Also, check the torque limit: r1538 for a positive direction of rotation and r1539 for a negative direction of rotation.
How do I fix a 'Ground fault' error on my Siemens Control Unit?
To resolve a ground fault error on your Siemens Control Unit, check the power cable connections, inspect the motor, examine the current transformer, and check the cables and contacts of the brake connection for any breaks.
