I replaced a somewhat tired Index 55 machine with a new and tighter Clausing Kindia FV-1 CNC with Dynapath 20 control. Apart from an electrolytic capacitor and power supply glitches, it's been running fine in jog mode as a manual machine (it has the pendant handwheel option). I'm now getting repetitive work, so need to get the machine working as it should.
I have the full Autocon-Dynapath manuals, and I can use a local machine shops Mastercam X mill-3 to write code. It sounds like your servo drives need tuning. Installation manual should tell how. What I think is happening, the Y axis drive is so far out of tune it can't handle the rapid move of a (0) event. Manually jogging the machine wouldn't get up to full rapid speed which may be why you didn't have this error previously.
Sep 30, 2009 - My J325 Tree had a Delta 20 control on it when I bought it. But the comments I've heard from people with the Dynapath controls.

I believe there's an operator screen that allows a mode where the feedrate override knob also controls rapid move rate. Activate that mode and run the program at 50% or less to see what happens.
My guess is it'll run then. If the override method worked, then tune the servos per instructions. Delta 20 is an old control. If it gets to the point where you aren't able to keep the servo drives in tune go into the parameters and reset the rapid rate down to maybe 150 ipm. It sounds like your servo drives need tuning.

Thanks peninsula and Doug, Quick update on Y-servo card error: I did 'tune' the card using the Dynapath instructions in the Installation Manual (attached). Alas, the lag settings were off a little, but just as soon as I tried the Fast Jog on the Y axis, the servo card would fail. (at least I know the correct process for tuning!). So, spoke to Glen at Dynapath. He suggested swapping the X and Y cards to see if the fault followed the card or was axis specific. Did so, the same card now failed on the X axis, so I know it is the card!

Got in touch with Servo Dynamics and received a helpful email that mentioned that the error I was describing is often due the power transistors failing. So, since I have a spare non-functioning SD 1525-17 card (came with the machine as a dead spare), I am going to work on that card to see if it can be brought back to life. Volvo l 70 e parts manual. The 4 power transistors the tech mentioned are in fact MOSFET's (4 x 2SK1277's).

And since the card has to be worked on, it is standard practice to change out any electrolytic capacitor(s). There is only one on the board (220uF, 200v, 85degF), that will get changed at the same time.
Since some of the items have to come from the west coast, I think this is a project that will be finished in the new year. I'll post an update at that time. In the meantime, I am running the machine with feedrate override mode On (Mode 5 TM1 enter). At some point, I will do what Doug has suggested and change the PROM rapid setting down to 200 ipm or a bit less. The work done on this machine isn't time critical, and less strain on the hardware and the servos might make it last longer!
Thought I'd finish off this thread now the machine is working fine. After soldering in 4 new MOSFET's, I quickly learned that if you don't change the mica insulation behind the power transistors, you can cause some interesting electrical shorts = 1 ruined servo board. Found a person selling an SD lathe control unit on ebay that used 2 x 1525-17 boards. Old new stock, so got new boards for $300 each (SD wanted $1700 shipped for one). Quickly learned that the Dynapath/Servo Dynamics initial pot.

Settings didn't work for my machine (although the manual is for my machine and controller). Couldn't eliminate motor oscillation. After reading through a lot of PM messages, found one that mentioned that the best way to setup a 'new card' is to take the Test Point resistor readings from the 'old' card using a DVM. After replicating the settings, the new card worked exactly as it should. I was then able to use the lag 'tuning' technique in the above posting to balance all the drives. Everything is working fine. The machine is setup with Rapid Override (TM-1) turned on (so the Feed Override pendent control will also control Rapid moves).
I do plan to alter the PROM settings to reduce the rapid feed from 300 ipm down to 150 ipm in due course. We do small run stuff, and limiting wear and tear is more important than cycle time.
