I actually measured the Z home signal on the AUF board just before the microcontroller.? Its 0V before the axis reaches home position, and goes to 4.4V when the home position is reached. (Thanks

I have an update and request for more help. I finally got the encoder installed and wired so that it looks like the old one.? I no longer get overflow or underflow alarm. When I enable the drives,

thanks for your help. I unplugged the encoder on Z and enabled the drives.? Nothing moved and I balanced Z and Y using a volt meter on TP3.? They were not far off already.? largest deviation was

The fan is a press on fit. Yes, it has a key. I pry it off. If it breaks, they are cheap (or used to be).

I have a new to me 1.5 hp motor off of a Vari-drive J-head that is not playing nice when I hook it up to a 3 hp static phase converter (with a 3 hp idler running). I have no issues running different

First: what your machine is doing is unusual. Without the drives enabled but the machine On, none of the Axis should move. Turn the drives ON and none of the Axis should move. The control will monitor

Thanks George, I have the maintenance manual and have attached the relevant chapter here I believe. I just found and read this chapter after I got your email.? It does help me understand what you

MSI drives. Let's see what I can send. JP4 is the encoder for Z?JP9 is the command There is a trouble shooting section in the maintenance manual which i cannot access right now.I will keep looking.

Thanks again. Here is a picture of the drive.? Not sure which type it is.? You can see the pots in the upper left.

I am not at home right now. In TN installing 2 Kitamura horizontal pallet changers. When i get home, i will see what i have in my computer in pdf. My boss sold his building so all my books are in

Thanks so much for your help George.? Without it (and some more to go I'm afraid) I'm going to have to scrap this old control and upgrade.? I'd really like to get it running as is though.? I've had

You have to understand the alarms. DAC overflow means the control commanded a move but did not see encoder pulses. Did the motor move? If yes you have a position loop problem. If not, you have a

Would the problem not be with the limit switch and or the home switch? On Mon, Jan 30, 2023 at 12:16 PM, Pathwizard<willg@...> wrote: I had a problem? with my V2XT where the z axis

I had a problem? with my V2XT where the z axis wouldn't home and it seemed to be overshooting. In my ignorance and brazenness, I broke the encoder on Z axis. I've since replaced the encoder with one

I should mention that EMI was modifying the AXSBOB and the AUXBOB boards with fuses. Might be a good idea to replace them. Also the original BMDC boards that were not surface mount had a piece of wire

Common issue. Starting with the cutler hammer controls on the EzTraks, the power goes through a piggy back board with circuit breakers. This protects the BMDC. To get people running, I used to take

If I had a part number I'd be good.? This is apparently a well known issue that happens when the 5V shorts.? Seems that this is a sacrificial component.? Although I've seen this referenced a number

Post a photo, also regulator number if available. Usually 5V circuits are 1 amp or less with the occasional 1.5 or 5 amp reg. Guesstimate value, 50uh-100uh.

My BMDC has been damaged by 5V short, which burned L1. Does anyone know what part I need to replace it with? Its surface mount. (What L value and what current capacity?) Thanks for any guidance. Will

Here's the parts of the self ejecting drawbar. My mill came to me with a drawbar made of a nut welded on some all thread, pretty crappy!
