Our vfd is a lenze m3220b. 240v 3 phase input. 2hp 3 phase output. It failed again after 2 yrs. of service. The drive is running a HSC20d pump. 1.2 SF, 6.4 Amp motor. The bridge rectifyier failed on the VFD. Service to the property is 240V 1 phase.
My question is can I use a 240v 1 phase VFD instead of a 3 phase 240v VFD for the input? What hp drive do I need to run a 2hp motor on a 1 phase 240v input.
I believe the drive is bing damaged due to an unballanced load on the input since the drive input is 3 phase. Using 3 phase in is lowering the hp to the motor by 50%.
