How can I solve this problem ?

Please find the information in the list manual of the DCM under the following link: https://support.industry.siemens.com/cs/document/109825202/sinamics-dcm-list-manual-firmware-version-5-1-sp1-(based-on-5-1-sp1)?dti=0&lc=en-WW For fault value = 207: Temporarily reduce the rated motor current (p50100) so that the rated motor current is significantly less than the device rated current (e.g. p50100 = 50 % of r50072[1]).
