Greetings Team, I purchased this kit a year ago and have now reached the stage of installing the hickory control. I removed all electrical components except for the limit switches for accessories such as the umbrella tool changer, gearbox proximity switches, etc. All electrical boxes and sheet metal were removed, sandblasted, and painted. I've begun a picture gallery as suggested

and have attached the schematics and manuals I'm using, specifically Schematic S15219. My software was version 5.0, so I upgraded to 5.20. I've also installed the MPG-6, and everything appears to be functioning well. I'm setting up this bench in my basement where I only have access to 220v single phase power. My shop is equipped with 240v 3 phase power with a wild leg. The Centroid schematic is quite clear, indicating that 220v single phase is connected to L1C and L2C. Ground to PE and G terminals.

Do I leave L1,L2,L3 open for the bench test?
I assume when I install in my shop (3 Phase) I will land wild leg on L1?
Do I install Leadshine motion studio on the CNCPC?

Thanks
Dan

Looking good so far!

I think you should be safe to leave L1, L2, L3 disconnected for the bench test with the caveat that you cannot command the motors to move. You'd be able to test communications to the drives, check encoder readings, and do some parameter setup but nothing that requires powering the motors.

I'm going to defer to someone with more knowledge on electrician stuff about the wild leg question.

You can install MotionStudio on the CNCPC or any other computer that is more convenient. It is not a bad idea to have it on the CNCPC since then you will always have the software and backed up parameter settings with the machine.

Thank you I appreciate the advice. I need to order the VFD for the spindle. It is a Mitsubishi SJ-11-AP. Max amperage is 64 and max input voltage is 200. See picture. It would also be 3 phase 240-volt input.


I have no experience with the products and would like to get the best bang for my buck. any suggestions?

I will have room in my electrical cabinet for the VFD with all other parts but also have a second cabinet on opposite side of the machine I can use. I was thinking of using the space to store all the tooling as it is next to the tool changer. Would it be best to install teh VFD far away from Hickory?

Thanks
Dan

Step 6 page 45 Hickory Installation Manual. (initial setup for Absolute Encoder) I believe I have set this up correctly but would like your confirmation I am correct. I have a 3 axis mill so I set P316 to 448? The next step is (Configuring Encoder Counts per Revolution) My encoder type is 23bit optical It appears one revolution of the encoder will be 32767 do I multiply by 4? I believe I am over my head at this point. LOL I need to verify my lead screws pitch per revolution as well. Please advise. Dan

Since you are using Leadshine EL7 drives and corresponding motors, the encoder resolution reported to the drive is 23 bits and the drives will be set to report 20 bit positions to the Hickory. The Hickory sets this up on the EL7 drives on startup. Your counts/rev setting should stay at the Hickory default of 1,048,576 counts/rev.

Correct, parameter 316 should be set to 448 for your 3 axis machine.

For the screw pitch, please follow TB36. If you are reluctant to drive the axis without having the pitch, you can try to rotate the screw manually to get a starting value.

I was able to complete everything up to item 6 Jog the Motors. I opted not to do this as I only had the single phase connected. I did however have one issue when I attempted Disable Stall Detection.

After manually rotating x,y,z

I was not able to get (stall detection disabled) to pop up. although I could see the rotation and the direction was correct as seen on x , y , z. I could only slightly move Z as it has a brake, but I could see it move one count in either direction. If you look at this next screen shot I see -65536 in the 8th axis. How do I clear that or is that an issue at this point?

8th axis encoder?

Thanks Dan

Looking at your previous report, you have Axis 8 set to encoder port 1. Are you planning on using that port for a spindle encoder? Is anything connected to it?

[Ahdsmall]

I have no spindle connected.

[centroid467]

It's not an issue really but if you want to get rid of the meaningless numbers, set parameter 315 to 0.0000.

OK I appreciate the information. I will start the wiring for the main panel I plan to install the VFD in the same panel. I will reach out to automation direct for VFD, contactors ,circuit breakers etc.
