Looking to hire someone to design my system (Yaskawa Drives)

[Rdslasers]

Hello, I’m looking to hire someone to draw out a electrical schematic for my mill and my acorn system. I have a Milltronics mill with Yaskawa drives, a hitachi VFD and a acorn board with a pendant controller. I already have the computer and touch screen monitor.
The mill is very basic as I removed the ATC and flood coolant. What I need is someone that is familiar with this setup that could design the schematic for me, so I can follow it and get this mill running. I’m not comfortable enough with the drives to create the hookup. It would be much cheaper to hire someone to create this than to wire it wrong and smoke a drive or servo motor. I would also need the parameter settings for the drives and VFD.
Contact me if your interested so we can discuss this further.

You don't provide enough information about WHICH model drives you have. They may not accept step and direction signals.
Please post pictures of your current control cabinet, the axis drives, the spindle drive, and their model numbers. What HP is the spindle motor?

Here is the Acorn System Schematic for an idea.
You need to be comfortable working with electrical/electronics, be able to follow the schematic, make adjustments where necessary AND FOLLOW good CNC control wiring practices in order to be successful.

Here are the specifics of my project. It’s a Milltronics Partner VM17B. It’s 3 phase power and has a 10 Hp motor. The service drives are Yaskawa SGDB-10ADG. The z servo motor is a SGMG-09A2ABC. The x and y servos are SGMG-09A2AB. The VFD for the motor is a Hitatchi WJ200-075LF. There is a brake resister on the motor, not sure of its value, but it is the stock one that came with the mill. The spindle has an encoder, but I cannot read the part number until I remove it.
The enclosure is a new cabinet, starting from scratch. I will be running this from a American Rotary converter with a 20 hp motor. I will be using the acorn controller with a pendant, a nuk computer and a touch screen monitor, along with a keyboard and trackball mouse. I am very unsure of myself when it comes to making the connections to the drives and VDF. I also am not sure about setting up the parameters for these.
I have limited prior knowledge with CNC controllers. I owned a CNC router that I used Vectric’s software to creat my signs and other items with. Since my machining is going to be light cutting,I removed the enclosure, flood coolant, and the ATC. This mill was acquired during a divorce sell and it was very reasonable, otherwise I would have purchased a Precision Mathews mill and converted it with servos and drives that are common. There is tons of documentation for those, and would have been much easier.
I don’t expect anybody else to invest time into my project for free. I’m looking for someone who can draw a schematic for hooking these drives up to the acorn, assisting me with the settings for the drives and the VFD, and setting up my encoder snd limit switch’s.

At first glance at looking at the manual, it appears only the SGDB-10ADG will accept Pulse/Dir. However I don't see that the SGMG drive will.
So Acorn may not be a possibility.
I am not completely familiar with the two Yaskawa drives, but a call to Centroid *might* help decide whether or not OAK would be a better fit.

I am attaching the manuals I found for the drives on line (it is good courtesy for the user to locate and post the manuals)

You need to post your location. You may have to have a Centroid Tech rep do the conversion for you. It won't be as trivial as doing say a router.
I would have kept the tool changer but certainly your choice.

If its now just a bed mill, I might consider upgrading the drives and motors. You have a lot to consider, and most importantly if you have the skills to carry out the CNC Control Conversion correctly and safely.

I can't get the other manual to load, file size to large....
The other thing you have to consider is properly programming the drives, including the Spindle VFD.

The SGDC (1999, for the manual linked above) and SGDB (2003, yours?) are different generations of the Sigma drives but even so, the (slightly) more recent SGDB still seems to be analog only. For step/dir, you seem to need a later generation (Sigma 3 or later?). Given their age, you may be best to replace them with a more modern generation from Yaskawa or consider an alternative such as Delta or a bare bones Chinesium (Lichuan etc). I got some used Yaskawa servo motors and drives from a Korean machine breaker for a fraction of the new price.

The braking resistors specified by Yaskawa tend to be fairly modest. I've struggled to bring the spindle to a decently quick stop on both my Yaskawa VFDs. May not be a problem if you are not in a hurry but they specify a minimum resistor value (maximum current) which prevents much improvement. For higher power VFDs, there's a bidirectional front end that allows you to regenerate into the mains network, giving faster decel rates.

You wouldn't need a phase converter if you selected a VFD that takes 220V input. The choice may be limited but it could save cost and complexity.

Thanks for the help. I was originally told the servos would accept pulse/dir. I think I’m going to just throw in the towel and sell the mill. I only bought this because it was $1,500 and came with two new Kurt DX6 vices, a new American Rotary 20 hp phase converter, new touch screen monitor, numerous tool holders and other items.

Then you are in at a very good price.
If the machine is decent, then it may be worth replacing the motors and drives.
What was wrong with the old control?

If you are going to sell it, list where you are located
Good luck

The old controller was damaged by the owner I bought it from during the move of the mill. It was used at Ford Motor Company for prototype work. I wanted to save it, but knew I was ok if I had to sell it and the other items. I think it would be much wiser for me to purchase a PM or Grizzley import mill and convert over, as these have been done and there’s more info about their conversion. Im located in Chillicothe Ohio. I appreciate your time responding.

Sounds fine.
