The result is same even if I did P971=1 (EEPROM save). I tried by keeping motor parameters in HP then also same problem that P100 is going back to 0 only. Suggest remedial measures. Thanking you, Vijay

Check operating instruction manual to know how to remove IO board(Appendices) and also how to set dip switch (Section 3.5.1) Then your data will not be changed You can download manual from here https://support.automation.siemens.com/WW/llisapi.dll/24294529?func=ll&objId=24294529&objAction=csView&nodeid0=10804928&lang=en&siteid=cseus&aktprim=0&extranet=standard&viewreg=WW&load=content&start=11&csSort=-DOCDATUMBEITRAG&subtype=133300

In contradict to manual,with full reference available frequency is reaching 60Hz ifswitch is in downward position, in theupward position it is reaching only 50 Hz. Thanks for your prompt response.

JensS Posts: 739 Rating: (55)	When changing from Europe to USA by using only p0100 the setup going lost with power cycle. It is needed to use the DIP. Might by you’ve taken the wrong one, see attachment. Attachment DIP_50_60Hz.pdf (290 Downloads)

Contact with Siemens office in your place...(only they could change firmware)... Best regards, Hristo Mihalev

If not, please quote me the firmware version of your MM440, and I will see if there is a later version. Cheers, Graeme Attachment P0100.JPG (228 Downloads)
