rated frequency of sinamics DCM

Dear Experts.

i have a sinamics dcm with 6RA8000-0MV62-0AA0- Z L01+S10 order code. the line voltage of sinamics is supply by 300 HZ PMG. the problem is, the thyristors firing irregularly!.  and some times they dose not firing. the thyristor is SKKT57.

i think the sinamics has problem to work with 300HZ voltage.

i will appereciate if sb can help me.

Hello.

According to the manual rated frequency of supply voltage for DCM is 45-65Hz. The option of operating with an extended frequency range can be provided on request.

Requirements apply for line quality and line interference
