OVERLOAD #3

[pertti]

my fadal 15xt -96 alerts motoroverload # 3 machine has not worked for me. I put the new x-axle amplifier. servo, ballscrew is ok. the fault is elekctric or parameters. but I can not find fault. ATC also alert you when rotated.

failure comes when I press JOG key x, y axle run 0.1sec and overload # 3
is displayed, press the reset JOG Emergency Thurs. when I press the alarm will be the same again.
rotated by hand ballscrew home but does not affect.

The error #3 is that the motor tach. is wired wrong.swap the 2 small wires on the motor and that should fix it.stock wiring is black to red/sheild to black but sometimes they are wrong from the factory,you may also need to swap the power leads if it still faults,there are 4 combinations to try.be sure to have the motor off of the screw in case it runs away,if you can jog it is ok.if still not working reseat the control card and check the wiring.

OK. whether any other ideas? here is now night. tomorrow I'll try new things.

if you go to fadalcnc.com you can download the troubleshooting manual for free.go through the diagnostics checklist.You may also just have a bad new motor,I have had several new motors be bad out of the box over the years.you can swap with another axis to rule out the motor and you can swap amps with another,the axis cards can also be swaped as long as you swap the axis selector jumper.

Who knows? I had rather hand jog to work but now does not work. what is problem? all of which triggers the emergency stop circuit?
