Hello, Presently, I am commissioning 15 A, 4-Q, 400VAC 6RA80 DC Master Controller (V1.2) getting it interfaced with 3rd Party Bridge (B6 Configuration) via Pulse Interface Card.Please refer to the attachment for the Pulse Interface Configuration.While doing the configuration, it was found that the with internal EMF feedback at connector r52951, the value is zero although the DC Voltage is developed at C and D terminals. In turn r50038 (Actual Armature Voltage) is also zero or it is fluctuating. Even when the drive state is 7.0, some voltage is developed around +15 VDC to - 15 VDC and it is continuously fluctuating. But it remains same even if the firing angle ref is changed at P50601. The same soultion is workable with 6RA70. Secondly, when X177:29 - 30 is used instead of internal feedback, then r50038 value is available but it is fluctuating a lot (about 70%) although the voltage at C and D remains stable. How can this problem get solved?? Moreover, is there any differnece between voltage feeback circuit of 6RA70 and 6RA80? Please help. Thanking you in advance.

You did select the wrong product! Use the SINAMICS DCM Control Module! http://support.automation.siemens.com/WW/view/en/52234840/133300 |
