Dear Technology Team!
Would you be so kind to tell me popularly about the difference between simple "du/dt filter + VPL" and "du/dt filter COMPACT + VPL" ------------------------------------------------------------------------------------------ |

Hello, you find these information in the SINAMICS engineering manual chapter 1.10.2: dv/dt filters plus VPL and dv/dt filters compact plus VPL are very effectively limiting both the voltage rate-of-rise dv/dt and the peak voltage VPP on the motor winding to the values given below. • dv/dt filter plus VPL: • Voltage rate-of-rise dv/dt < 500 V/µs • Peak voltage VPP (typically) < 1000 V for VLine < 575 V • Peak voltage VPP (typically) < 1250 V for 660 V < VLine < 690 V • dv/dt filter compact plus VPL: • Voltage rate-of-rise dv/dt < 1600 V/µs • Peak voltage VPP (typically) < 1150 V for VLine < 575 V • Peak voltage VPP (typically) < 1400 V for 660 V < VLine < 690 V The dv/dt filter plus VPL is capable of limiting the peak voltage to values below the limit curve stipulated in IEC/TS 60034-17:2006 (VPP < 1350 V), and the dv/dt filter compact plus VPL is capable of limiting the peak voltage to values below the limit curve A stipulated in IEC/TS 60034-25:2007 (VPP< 1560 V). Additional the maximum permissible motor cable length are different. |
