HELP ON SANYO TCM-V822 HIGH SPEED MOUNTER

It could be the servo pack. We shut down the machine sometimes back and lastly sold it. The servo pack doesn't last long. Anyway,good luck to you.

You can contact Hitachi High Technologies America, they are still supporting these machines (972-615-9102). It also sounds like you could have a servo problem.

We have a TCM-V822 over in the warehouse that had a severe head crash.

If you suspect you have a bad servopack, contact Unidec. They can test it for you. If it tests bad they can rebuild it for you and you won't have to wait for months to have one custom built for you in Japan.

They tested one of mine for free and it turns out it was fine. http://www.unidec.com. I took the servopacks out of my V822 for spares (we still have a V850). I looked up your error codes in the V822 troubleshooting manual. REEL TIMING 01 18 - "The R axis is not stopped when it takes the next action" REEL SERVO ALARM 01 01 - "An error signal from the R-axis servomotor driver was detected." "Check the 7-segment LED display on the servomotor driver."

The 7-segment display will give you an error code. I don't have the error codes in front of me right now, but the datasheets are still available. It might give you a clue as to what condition the servopack is in (Maybe it's over current, over heat, under voltage, over voltage... something?) If you don't know, the R-axis servopack is near the center of the machine behind the back covers. It's the big one on the far left.

When I had trouble, it was with the XY table. My errors were XY TIMING 01 XX "The X axis or the Y axis is not stopped when it takes the next action" and XY INTERLOCK 01 XX "The X axis worked at an index angle at which it should not work". It turned out my servopack was fine, but the table was actually binding and causing an overcurrent condition in the servopack.

You have 5 green LEDs on your reel axis servopack (P, MP, A, B, C). Origin your feeder carriages and look at these LEDs. C should be on steady, as I believe this is your "home" LED. A and B should not be flashing. It doesn't matter if they are on or off.. or if one is on and the other is off, but they shouldn't be flashing. If they are flashing, adjust the "zero" potentiometer slowly until they stop flashing. You shouldn't have to turn it far from the factory markings on the pot.

While you're down there, observe all the other pots. If some of them have been changed from their factory settings... someone probably played with them and it might be a good idea to turn them all back to the marked factory settings and try running your machine that way.
