| John Rudd:
Moving swiftly along to the next in this series of millmodding,I'm doing a 3 phase conversion using an inverter. Pictures of the motor and inverter are already in the riser block thread so I wont show them again. So after removing the original motor, the new one is bolted in place. its a direct swap, both are frame 90 size, so I wouldnt expect any issues here. The motor was prewired with its supply cables, all I have to do is run some flexy trunk from it to the inverter... More to follow, meanwhile the obligatory picture ot two. :zap: |

So,had a bit of a break from posting about this..... Its all done, wired up, inverter programmed and away we go.. I mounted the inverter enclosure on the back of the mill, seemed to be the most logical place to put it..Out of harms way and close to supplies and motor. |
| John Rudd:
Now the most difficult part of this mod was deciding on where the controls were going to go :scratch: I had already mounted them into a suitable box and after much agonising, I settled for just under the Y axis at the front on the knee.... |
| John Rudd:
After trying out the controls and generally messing with the mill, I concluded that their location was justified. I was going to try and combine the nvr switch with them but I could'tt get a box suitable to house the whole lot....Anyway it looks ok, just need a label now for the FWD-OFF-REV switch and speed pot.. See what you think? |

Neat. I need to do the same thing. Do you have the nvr switch supplying the vfd? When I tried that the standby current of the vfd wasn't enough to hold it on. Russell -russ |
