What to do if Siemens Control Unit displays 'Monitoring time, sign-of-life expired'?
- Ddaniel18Sep 23, 2025
If your Siemens Control Unit displays 'Monitoring time, sign-of-life expired', check the PROFINET connection.
What to do if Siemens Control Unit displays 'Monitoring time, sign-of-life expired'?
If your Siemens Control Unit displays 'Monitoring time, sign-of-life expired', check the PROFINET connection.
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.
What to do if Siemens SINAMICS G120D shows F30004 error?
To troubleshoot the F30004 fault on your Siemens Media Converter, start by checking if the converter fan is running and ensure the ambient temperature is within the allowed range. Also, verify that the motor isn't overloaded and consider reducing the pulse frequency.
What to do if Siemens Media Converter displays 'Unit switchover: Calculation of the parameter values after reference value change unsuccessful'?
If your Siemens Media Converter displays 'Unit switchover: Calculation of the parameter values after reference value change unsuccessful', select the value of the reference parameter so that the parameters involved can be calculated in the per unit notation.
How do I fix 'Frequency at the probe input too high' on my Siemens Control Unit?
To resolve the 'Frequency at the probe input too high' error on your Siemens Control Unit, reduce the frequency of the pulses at the probe input.
What to do if Siemens Control Unit displays 'Torque/speed too low'?
If your Siemens Control Unit displays 'Torque/speed too low', check the connection between the motor and the load. Adapt the parameterization corresponding to the load.
What should I do if my Siemens Media Converter says 'PROFIBUS: Cyclic connection interrupt'?
If your Siemens Media Converter shows 'PROFIBUS: Cyclic connection interrupt', you should establish the PROFIBUS connection and activate the PROFIBUS master with cyclic operation.
What to do if Siemens Media Converter displays 'STOP cam approached with the incorrect traversing direction'?
If your Siemens Media Converter displays 'STOP cam approached with the incorrect traversing direction', check the wiring of the STOP cam.
What to do if Siemens Control Unit displays 'Write task for parameter rejected'?
If your Siemens Control Unit displays 'Write task for parameter rejected', the converter should be reset to the factory setting. However, resetting the safety functions is not allowed because they are currently enabled. Remedy with operator panel: p0010 = 30, Parameter reset; p9761 = …, Enter password for the safety functions; p0970 = 5, Reset Start Safety Parameter. The converter sets p0970 = 5 if it has reset the parameters. Then reset the converter to the factory setting again.
What to do if Siemens Media Converter displays 'Motor temperature sensor fault'?
If the Siemens Media Converter displays a 'Motor temperature sensor fault', ensure the sensor is correctly connected, verify the parameterization, or deactivate the temperature sensor fault.
