AllInOneDC Power On Behavior

Post by johnballard »

Hi,

I'm very happy with my Lagunmatic 250 milling machine with AllInOneDC retrofit. I recently eliminated my phase generator and replaced the reversing contactors with VFD's. Everything is working nicely on 240V single phase and I have been making money.

I have one leftover issue. Once in a while I will power the mill off when the z-axis is at the Z+ limit (where it has to be to use the air operated drawbar). When I power back up, I cannot home the mill. I cannot jog either. I have to remove the cover from the z drive, manually move Z off the z+ limit, and then I can home. I don't like getting my fingers into the belt drive :o

I'm sure there are many things I can do, but I would appreciate any advice.

p.s. I made some changes to the source code to run the VFD's. Also, I have two lube pumps; one for the ways, the other for the screws (different oil). The NO alarms were connected in parallel, but I will change them over to NC and provide both inputs to the PLC to have separate 'low oil' messages.

You should be able to select Slow, Continuous jog mode, then press the yellow Z-minus jog button to jog down until the limit switch clears.

Have you tried that?

No, I don't think so. I will test that tomorrow.

I knew there must have been an easy way...
