Mits 4A

what mean alarm Z 70 0008 ?

You might need to check your information on the model you've identified
Mitsubishi never produced a model 4. The controller series

went L0, L1, L2, L3, L300 L500 and so on.

Either way a Z70 alarm is thrown when your machine looses its
absolute position information (i.e. your machine home has been lost)

This problem usually occurs when a - a battery went dead, or there's a
bad encoder.

You can download the correct instruction/operation manual from
meau . com in the US, and there will be instructions on how to
reestablish you home positions.

I think he's referring to the machine model MH4A.

[karci]

yes it is MH 4A

If it's an MHI machine with a Mitsubishi control, then you
will want to verify the controller model number by looking
at your diagnostics screen or the model number of the control.

These machines might have come with a M500 or M600 controller
from Mitsubishi Electric.

THE Z70 alarm means that your absolute position was lost,
as noted in my previous post.

Once you establish what controller model you have, you can
download the correct manual from www. meau . com to
see how to reestablish that postion information
