VFD DC Overvoltage में Trip हो रहा है ? DC Overvoltage Fault क्यूँ होता है ? VFD Troubleshooting | #vfd #overvoltage #dc #electrical #bolbulbulindustrialelectrical
Sir, good evening . Your very nice explanation. I wish to ask why dc bus high voltage fault where as dc bus voltage is 580V and as soon as giving power tripping.
Hi sir hamare paas dalta El vfd ka ou error araha ha. Input 220v to 240 ha aur out put 3 phase 220v ha. Jasay he main run karta hun aik dam ou ka error Ata ha. Jab gear motor ke wires ko hatata hu phir fault nahi data. Please help me
Motor decoupling karne se sahi chal Raha hai ? Ou fault means DC bus overvoltage. Agar load jyada hoga ya jamming condition hoga to ye fault ayega. Motor & gear box check kare.
Sir ACS 355 mai f0001 code aa rha hai overcurrent ka motor ka IR , WR sahi hai decouple karvake uski shaft ko ghuma kar dekh liya hai koi jamming nahi hai Phir bhi vo fault dikha rha hai aur rpm 11 se 12 tak hi jaa rha tha ( sidha drive ko replace kar du )
Hello mam I have danfoss fc102 which is running smoothly. But i am getting an alarm repeatedly as( 2 warnings see alarm log) i checked and found its earth fault and short circuit. I checked the circuit and motor found everything in condition. Please help me to find the solution for this.
Does motor trip or alarm comes in running condition ? If motor trips , disconnect the motor and start the VFD. Measure the voltage . If it's trip then fault is in VFD.
@@BOLBULBULIndustrialElectrical sir hamare site me Ahu's Moter ke liye 15kw ka abb vfd drive laga huwa hai use trip alarm show ho raha aur vfd only hand mode me run ho raha please sir problem kya ho sakta hai bataye please
VFD is variable frequency drive. VFD incoming supply is in 50 HZ . But output supply is in variable frequency. To obtain that variable frequency incoming AC supply is concerted to DC. Then by modulating that DC we get different frequency voltage .
