It looks like I need to start by testing the A50L-0001-0175 IGBT modules. The machine indicated it was in high gear. But it should have been in low. I suspect it overloaded while tapping but I wasn't...
The AC spindle servo unit appears to be a 15S series.

I think the service manual is GFZ-65015E. I'm reading the PDF now.
I found...
Opened the cabinet and took a look. I have an AL-12 alarm on the spindle drIve.
I found this thread that covers some possible repairs....
Yesterday while rigid tapping the tap bound up and generated an error. In my haste, I rebooted the machine and removed the tap without capturing the error. I thought maybe I'd bottomed out but it was...
I disassembled the gearbox and cleaned it up in the parts washer. I greased everything with fresh grease. I used Mobilux EP2 because that's what I had on hand. I put everything back together. I did...
Relays all checked out. I pulled the motor and water/coolant poured out of the motor. I split the gearbox from the motor and the motor was froze up. Gearbox and the motor had a visible water line. I...
The sensor that corresponds with DGN #1002.7 appears to be working. It's at the end of the shaft on the right side. When I press the button to home the magazine the motor that drives the right angle...
I looked up the error in the operating manual and it states:
The magazine does not rotate although the magazine start command has been issued. Or the magazine shifted. Either a sensor error or...
servtech, your suggestion was spot on. I replaced the poppers yesterday morning and so far no more oil pressure issues. After replacement I tested with paper and the flow looked very even. I suspect...
Thanks so much for your help. They turned out to be AJB-1 which crossed to the HJB-1 that I ordered this morning. I ordered enough to replace them all. I'll see how it goes in a few days when the...
I figured out what I need. I'll pull the size off the units in the morning and get some coming. I'll bet they're gummed up and stuck open. Can they be cleaned? Or is it not worth the effort?
...
That makes a lot of sense. Is the shoe lubricator at the shoe, maybe the brass block where the tube connects? Or located at the distribution? I assume I'm looking for a poppet valve of some form.
I blocked off after the pressure switch and confirmed the pump maintained pressure and the switch appears to function correctly. I removed the back panel so I could get a better view. With the Y axis...
I'm suspecting a leak someplace. I verified the pump motor is running and the pump cam appears to be moving very slowly, as it should. If I pump it up and then come back a few minutes later the...
The machine has been off for a few months. Today when I brought up the machine I noticed it would only execute one line at time, like it was in single block mode. Checking the alarm screen I seeing...
I edited the ladder on my 0TA a couple of years ago to add chuck clamp/unclamp for bar pulling. I used an eprom programmer, I bought off Amazon, to download the binaries off the eprom chips. Dalvi...
I run an 0TA control on a SZIM lathe. As lshingleton mentioned, you'll want to use G74.
You may find this handy:...
I think I have this sorted. I hosed down all the pockets with some fresh coolant. I then mixed up a dilute solution of cimclean and sprayed down each pocket and gave them a good scrub with a nylon...
I'm thinking my pockets are simply gummed up. It has been a very hot summer and we've been running infrequently. I'm now in the process of removing all the tools from the belt. What is the best...
Alright, this morning I reset the arm and checked my codes before re-attempting. Rather than swapping to the same tool I was attempting previously I randomly selected another and it changed without...
The tool changer arm on my Matsuura MC1000V7 is rotating into position, the drawbar activates (release), but the arm doesn't drop down to complete the change. After a few seconds it generates the...
I'm beginning to suspect my spindle encoder may be the cause. Today I'm running parts that are all in HI gear, no speed changes, and my drives are turning off at the END of my program. The parts are...
Ok, I think I have this fixed. In MDI if I run S0M3 the spindle was hovering around 2 to 3 rpm. That's a lot of drift. My understanding it should be 2 rpm or less to prevent tool change issues. The...

I ran a couple dozen parts and never once had a timeout issue shifting from HI to LO but going from LO to HI would timeout every other time. After re-enabling the drives and homing the carousel the...
Lubricator was full of oil. Can't recall when I last topped it up. Maybe it's not working. I pulled some lines and added a drop or two of oil. Cycled the gearbox for an hour or so. Lots of failures....
Recently, when shifting from LO to HI gear, say 1000 rpm to 7500 rpm, the shift has been timing out. I have to re-enable the drives, re-home, and then it's good at full speed. Shift down again and...
+1 on losing steps. Check the Z axis screw is clean and lubricated. I've had similar issues on my 4000. It's typically time to clean and lubricate when steps are lost and/or my speeds and feeds are...
I have the IN/OUT issue sorted. I must have changed something in the serial parameters when I installed the Calmotion USBCNC-INT DNC. Fortunately I had dumped all the settings prior to moving the...
