vidhyadharan Posts: 39 Rating: (1)	dEAR sIR, Im using sinamics G120 90KW VFD,And Im using the control unit CU240E-2DP FOR FAN APPLICATION. MY VFD IS GEETING TRIPPED WHEN THE VOLTAGE FLUCTUATION COMES FOR 2SEC. But I dont want my VFD gets tripped that time. I have enabled the kinetic buffering as well as reduced the Vmin level to 65% But still My VFD is getting tripped during the power fluctuation. If the VFD is tripped then total plant will come to standstill. Please help me to sort out this issue

Do you know that if you are in U/f control mode, you should use P1280 instead of P1240 to activate the buffering? Also P210 should be decreased if possible. Is it also possible to activate restart P1210.
