    Re: New to me Tree Journeyman 425

    Trying to figure out which terminals on the HY GT 7.5kW VFD to connect the Acorn 0-10vdc analog output to. This is a photo of the terminal board. The terminals don’t match the manual exactly.. I have the parameters configured to us AI1, I think. Forward and reverse commands are working correctly (they were not wired yet when I took this photo).

    Looks like you use GND and A1

    Re: New to me Tree Journeyman 425

    That's what I thought, too. I tried the GND terminal next to AI1 last night and it didn't work. Thinking I'll try the GND on the upper row between +10v and S1..

    That makes sense. Who knows how they wired the thing internally.

    Switched to AI2 and assigned it to speed control in the settings. Connected to the GND terminal next to AI1 and the AI2 terminal. Now have speed control.

    Awesome. Looks like their manual needs a little more clarity.

    Indeed it does.

    Just took the first cut. Used Intercon to write the simple program. I have some learning to do. It went well!

    New to me Tree Journeyman 425

    Received the Hitachi SJ-P1 drive for the spindle. This is a very nice drive. And, they are rated for single phase supply to very high HP levels. I bought the P1-00800-LFUF 15kW model rated for 31a output continuous when powered from single phase. Drive comes with bracket for wall or through wall mounting which places the heat sink and fans outside the enclosure. This is how the original drive was mounted when it was new. I had to open up the hole a little.







    The spindle motor has an encoder and Hitachi has an encoder interface option for the P1 drive. I think I’m going to give closed loop sensor vector a try and see what that’s like. I’ll also have a chance to run the thermistor wire to the drive when I run the encoder wire and replace the motor main leads with modern VFD cable.

    I’m adding a few relays when they get here. I want the spindle fan to run for a few minutes after the spindle stops, so I ordered an off delay timer. And, I need to replicate the spindle FWD and REV outputs to drive the spindle fan contactor.

    The machine is getting close. I’ll get the probe receptacle and spindle load meter wired and I’ll be pretty much done with the conversion. Very happy with the machine thus far.

    Short video of the spindle and drive doing their thing.

    Getting close to completing the mill build. Still a few details. Got the way covers cut out of rubber sheet. Looks like it will do the job. Touch probe receptacle is in and the probe works great with the built in probing cycles.



    This was a bore probing cycle on a 1.0000 Mitutoyo ring gauge.



    Plan is to make a keyboard tray/mount like so:


    Starting to look the part. Next up is getting the table chip enclosure back on.

    For the most part, the mill is ready to use. As I type that I realize I have some tidying up to do with the air stuff and the wire trough cover.

    Used it for a real job tonight. The Y axis cover needed clearance for the position of the new motor pulley. There is a knockout in the cover. Used the probe to locate the existing hole. Mind blowing how well this works! I’ll make an appropriate cover for the opening.



    As it sits now with chip shields in place. The table is really high when close to the quill. 48” in these photos.

    This is such a cool project. Great work. What monitor did you choose?

    Asus VT168H 15.6” 1366x768 HDMI VGA 10-Point Touch. Very happy with the screen. Size was a driving factor for choosing this monitor. No complaints. I bought an Amazon Warehouse deal and was about $50 less than normal price.
