More Viper problems

[kilrabit]

Having trouble with two Viper 100 boards bought last March.

One blinks red rapidly as soon as I turn it on, it got increasingly worse over a period of about 4 months on tripping out. As long as the machine was running, it would work fine. Spent many hours retuning, and checking electronics. If that axis sat still for more than 3 minutes, the board would fault out. I took this one out and moved a spare to that axis, a viper 200, am still waiting for a programmable fix for the board so the axis do not jump, without going through extra steps.

I now have another board that is doing the same as the previous, they are the same age.

Can you tell me what the problem is? Or how I can fix this without throwing them in the trash?


It seems to be saying that there is over amperage, but when I check the amps running, very seldom over 4 amps of current. I have checked the tuning repeatedly and cannot see a problem.

Where are you, Kilrabit? I'm in Dublin and about to start a 4 axis retrofit with the viper 200's. What breakout board are you using, in any. What controller?

I use a c-10 BOB from cnc4pc.

I use Mach3 as a controler

If you want to return them, i will check and fix them for you.
You just pay shipping.

What size motors ? what voltage are you running ?

Larkin,


I am running 1200 oz servos, at 72 volts.


If you could tell me what you think is the problem, I will fix them here. It will take about 10 days round trip to Canada and back. Also do you have the fix for the field programming in the field on my other boards? The trim and amp adjustment work fine , when you turn them down, the yellow and red lights come on as they are supposed to. The red just continues to flash rapidly, if I move it to another axis it does the same.

i r machinist,

I am about 120 miles west of San Antonio tx. Northwest of Uvalde about 30 miles. Out in the middle of nowhere, which sure is nice.

Camp Wood area? Did some hunting there. I'm from Ozona and McCamey, which is just a little closer to nowhere (Sanderson) than where you are. I've still got family in Ozona, but spend my vacations at a place we have outside of San Angelo. What are you wiring up?

Tell me all your drive settings.Use ? and 1 and 2
What version is the firmware , use the v command.

Do the drives hold (lock) in both directions if you turn the shaft.

I wish i lived in Texas... you should come up here to canada and i'll show you real cold and wilderness.

Larkin,

I did not check to see if it was still holding when it trips out, I will be back up there Saturday, and let you know. Also the version number, I think it was 2.6 but will double check. I did notice when I used the "z" command it did not set to factory defaults. I will try using another bank when I get back.

i r machinist,

I am 28 NW miles from Uvalde, 26 miles SW from Camp Wood, and 25 miles E from Brackettville, on the West Nueces river. That will put you in the general area.

This set of boards are on a 10' X 6.5' Gantry Router

Larkin,

The firmware is 2.6h, and when faulted out no power to the servo, free wheeling
