I was working on the coolant pump Thursday. Wired it up on Low voltage in Delta configuration and hooked up the smallest Capacitor I had on hand. I could feel a Hum on the casing, but no coolant. On and off trying a few different things and smelled smoke. Not good. Next day reached out to my high sc...

I see from the pic I did not have one of the X+ home was not set either. That took a few minutes to realize when I was trying to "set" home.

Bingo! Thank you!!

Presuming you mean that INP16, on the Alt-i display, changes from Green to Red when you trip the X+ limit switch, then the next step is to make sure that you have entered "16" as the X+ limit input number, on the Machine Configuration -> Motor Parameters table. Yes that is what I meant. T...

I confirmed with a meter that I have continuity from the switch to the input, the LED confirms that, but wanted to make sure the wiring was correct.

Ok, following the Centroid Hardinge Retrofit Manual rev 041104 I see I should be checking for limits and home to be set to 1 for Z-, 2 for Z+, 3 for X- and 4 for X+. Not sure where to see this as referenced. If they mean Inputs 1 to 4 , I find them as inputs 13 to 16, which lines up with the paramet...

Working on X- (8LS) and X+ (7LS) limit switches today. This lathe is equipped with the X home (9LS) switch but it is not hooked up. Looking at the drawings that came with the lathe it was not even called out. Well the yellow wire is called out, but go to an empty spot on the terminal block. Anywho.....

Everything seems to be working now. I had to do a factory reset in the VFD and go over the settings. Also moved a few wires once I got a better grasp on what had to go with what. Spindle works. X and Z both work. Turret indexer works. Collet closer works. I do need to check the limit switches since ...

I couldn't take it any longer. I hit Run on the VFD. Motor ran. Was a little loud on the chirping. Then I read thst the motor playe info needed to be entered before starting the motor. Got that info in the best I could. Read somewhere about the Autotune. Got that ran. Still hearing a chirpping as th...

Well looky there....the answer is right in the first pic I took with the terminals in it.

Now why are the instruction manual showing a different layout as to what is on the VFD?
