Problem- System stopped working, will not home or jog.

[AnthonyOhio]

Centroid CNC11 with DC3IO and Ajax 29in/lb motors.
This is a newer system, only used about 30 days since install.

The system was working on thurday without any problems. I finished a part and performed a normal shut-down.

Saturday I turned on the machine and pressed cycle start to home the machine and received an error regarding the optical connection. I attempted to jog the machine in all axis and it failed showing 410 errors on x, y, & z, and one 411 error on Z.

I shut down the system, remove each fiber optic cable blew the connector out with air and reinstalled one at a time.
(when I received this drive it did not have plugs preventing dust/dirt from entering the fiber optic ports, and the base was bent. )

Rebooted the system. =same problem
(1) 05-14-2011 13:59:18 199 CNC Started
(1) 05-14-2011 13:59:18 Dual port base address = 0
(1) 05-14-2011 13:59:40 411 Z axis(3) full power without motion [homing attempt]
(1) 05-14-2011 13:59:45 406 Emergency stop detected
(1) 05-14-2011 13:59:47 410 Z axis(3) position error [jogging attempt, same result on all axis]

I tested the limit switches using the alt-i screen. =OK
Checked servo power supply voltage. =OK
I Turned off stall detection. =No movement of servo motor
Connected motor leads to servo power directy. =Motor works
The drive board displays #1 (as it should)
The MPU11 has the 3 solid and 1 flashing led (as they should be)
All machine voltages are normal.

Monday
I rebooted the system and I still have the same problem.

I believe that the drive board may be dead.

Any ideas, I am out of things to check.

That sucks! i got that 410 error on a couple of my mills latly, and found the power supply, 12v &5v was out. (Its on the back of the drive) one of the power supplies showed the volts good, but it didnt have any amps. If yours is working, Being very carefull so you don't electricute yourself, did you try to manually (with a insulated handle screwdriver) push in the E-Stop contactor and jog an axis? if the axis jogs while holding in the e stop contactor, then something in your e stop circuit is bad. of coarse, im assuming the e stop contactor never pulled in.

follow your e stop circuit, check for continuity where it goes through the axis drive, amoung other places.


no power comming to the drive from the encoders, will stop it from comming alive. Are all your encoders plugged in?

Did you build this system yourself? If not, have whoever built it check it out.

Centroid/Ajax does have some dang nice hardware and software, unless yours was abused somehow, i think your problem is fairly simple.

Good Luck

I replaced the driveboard and everything is good.
I agree that this system is far better than many out there and i enjoy using this machine.
