Re: To shunt or not to shunt? (shunt regulator)
Great, thanks for the response. I intend to let the motors fail if they are going bad and then replace them, is there a risk with doing this? My long term goal is to convert the lathe to CNC, learn to make a POST for Pro-E then sell off everything and go shopping for better equipment (another couple...

Re: To shunt or not to shunt? (shunt regulator)
Hi Scott, OK between changing the taps and removing a cap on my rotary phase converter I have the DC voltage down to 118VDC no load and 102 with the mill spindle on. When I start my lathe with the mill running the voltage goes to 100 VDC. Am I OK to run? Hope you can get back to me I want to start i...

shunt regulator / phase converter issues
I am still in a bind. The X-former taps are set to 250VAC (highest setting) and I went out and bought an infrared thermometer at harbor freight. Here are the things I tried with results. Spindle on, no shunt regulator, I get 112 VDC Spindle off, no shunt regulator, I get 128 VDC (is this too high?) ...

Re: To shunt or not to shunt? (shunt regulator)
"Not to Shunt"
I'll pull the shunt regulator and make adjustments.
The shunt regulator would have been connected to the cap before the DC3IOB.
Glad I asked before I installed. Fun starts tonight If I can make 110DC without it.
Thanks for the input.
Regards,
Chris

Re: To shunt or not to shunt? (shunt regulator)
Hi Scott, On my 5hp lathe, I have an issue where the coolant pump overload contactor trips when not running the spindle at the same time. I believe this is because of the wild leg on the rotary phase converter. I wanted to make sure the mill did not have this issue as it is only 3 hp. I am using a F...

To shunt or not to shunt? (shunt regulator)
Hello out there, Last time I was working on my project I cleaned up all my wiring and powered up to check the DC supply. 110VDC on the dot. I am ready for my install now and I decided to let everything run for 30 minutes. I am running off a 10ph rotary phase converter and have a wild leg and just wa...

SD1 in place of DC1
Is it possible to install and use an AC servo with a DC3IOB/MPU11 kit. I have purchased a Nikken rotary table thinking I would change over the servo, I think I can do it buy I'll have to disassemble a spare servo I have and put a taper and a key on it. Worried about even small amount of run out. I a...

electronic gearing and gear hobbing
Is it possible to drive a 4th axis as a slave to the spindle to hob a gear using Centroid software?

Check out this link.

Not recommending it, just thought it was interesting.

Re: manual Z axis help/ideas wanted
OK this is good. Can I add a single hand wheel to run Z? If so can I hack the design to make a handle similar to what you would see on the side of a Bridgeport head. Also is there a way to get the % load of the z-axis servo out to the outside world? I am a mechanical design engineer by day and have ...
