Hi all,
I've got a mirac that i had a few problems a couple of years ago but got it all up a running, It's been standing still for over a year now, i switched it on but doesn't reset/home - if i click the axis override button i can hear/see the stepper motors trying to move, i can freely move them otherwise.
My pc doesnt connect to the machine either, but im sure if the machine was able to reset, it would connect
The reset button is also a dud - its not connected to anything. any ideas?
thank you for any help in advance.

Re: Mirac not resetting.
Has the X or Z axis gone on to a limit switch?
Press & hold the "Axis Limit Switch Overide" button & home the machine. Then release the button.

hi, yes it has a limit switch by i've manually moved it into a position where it is not activating the switch.
When i press the override button, it does try to go home, even when the machine is not linked to the PC
I have tried to home the machine while pressing the button, but it says that it is not connected.
The eurocard also shows a .C on it, not even a 8 or S.
any other ideas?

Re: Mirac not resetting.
A "C" in the Eurocard usually means Circular Interpolation, so I dont know how this is occuring. With the power off try unseating and then reseating all the cards in the rack and ensure that the ribbon cable are firmly in place
The Axis Override button when pressed and held should power up the ESR (Emergency Stop Relay) See drawing attached
I can work out why the machine would try to HOME when the PC is not connectedWhen i press the override button, it does try to go home, even when the machine is not linked to the PC

Re: Mirac not resetting.
I can't understand how it could be moving/homing without the PC connected, unless it is a Fanuc Mirac and the PC is used for drip feeding??
I think a couple of photos of the machine, PC, software and electrical cabinet would help us guess what the problem could be...

Re: Mirac not resetting.
Good thinking Administrator ...................The Serial No and Year of Manufacture of the Mirac would help
Re: Mirac not resetting.
Hi guys, thank you for the information,
hmm, when i meant the machine is trying to home, could it be that it is trying to jog to its original settings, i remember that it used to do this as soon as you switched it on, it would jog slightly.
I will get some photos up soon.
I will give all the cards a clean now while i wait for the camera.
