Hello,

What kind of experience you have with this fault in SINAMICS DCM ?

Problem is Under voltage of the of the Input power & Tolerance of the drive. 

I want to increase parameter p 50361 from Factory setting 0 ms, to e.g. 30 ms or 50 ms.

What is the limit for the time in ms, because I don't want to burn the thyristors. 

Thanks

Very rarely this fault is observed/trigered, since drive input supply voltage has wide tolerance i.e. in general -20% to +15%.

BTW have you entered correct input supply voltage value in p50078[0] & [1]? Which area i.e. whether in armature circuit or field circuit undervoltage is detected? Have you checked?

Max 60000ms value user can set in p50361. Are you facing undervoltage or supply voltage dip problem? Because even setting delay time in p50361 (max of 60 sec) if undervoltage detection continues for so long time, drive will trigger fault F60006.

HTH.

Hi Sim1998

We had a similar issue 4 times this month. We are suspecting that it was the utility company issue, but we just wanted to be sure that there is something else we can do in the DC drive to fix this issue or at least to minimize it. Were you able to change the parameters 50351 and 500361? Did you have the same failure again? I appreciate it if you can share any other information that could help us to solve this issue.

Thank you
