Changes to the motor thermal protection feature of the MICROMASTER, SIMATIC &
SINAMICS inverters
On 9th November 2010 Underwriters Laboratories Inc.(UL) revised the standard for "safety of power
conversion equipment" which covers Siemens inverters. These changes in the standard become effective
from the 9th of May 2013.
The changes relate to the performance of the software motor protection offered by the inverter, in that
when the inverter is power-cycled it must now retain the motor temperature data for use when power is
reapplied.
The following products have had a software update to comply with the new requirements.
• MICROMASTER 420 software V1.3 or above.
• MICROMASTER 430 software V2.2 or above.
• MICROMASTER 440 software V2.2 or above.
• SINAMICS G110 software V1.2 or above.
• SINAMICS G110D software V3.6 or above.
• SINAMICS Pool CU-2 software V4.6 or above
(CU230P-2, CU240E-2, CU240B-2, G120C, CU240D-2, CU250D-2).
• SIMATIC ET200pro FC-2 software V4.7 or above
These products now, by default, store the motor temperature (r0034 for SINAMICS G110 and
MICROMASTER 420; r0035 for SINAMICS G110D and MICROMASTER 430/440) and re-use this value
when power is reapplied:
Parameter P0610 has been changed to reflect this new requirement as follows:
The default value of parameter P0610 is now 6 and the following settings have been added:
• Value 4 = Warning Only, no reaction, no trip, save temperature on power down.
• Value 5 = Warning, Imax reduction, trip F0011, save temperature on power down.
• Value 6 = Warning , no reaction, trip F0011, save temperature on power down.
*) Those units have other settings and default values. Please refer to the relevant parameter lists.
The following products will not have the software update to support the new requirements.
• All MICROMASTER 3 variants
• All MICROMASTER 410
• All MICROMASTER 411
• All MICROMASTER 436
• All MICROMASTER MMI / CM2
These products are unchanged from their original design, but this is no longer compliant with the new
requirements.
These products may still bear the UL symbol but it is now the end users responsibility to provide listed
motor overload protection external to the inverter.
We suggest the end user consider devices such as the Siemens overload relay 3RU series on the motor
side of the inverter in order to provide the motor protection, details of which can be found at the link
