Hello Guys,

owning a 1981 Mori seiki SL1H with Fanuc 6T controls the following problem occurred; after switching off the machine one day when it was working properly and later switching it on again, when powering on the cnc control only these alarm messages appeared and the control refuses to switch on:

210 + X ot
211 - X ot
220 + Z ot
221 - Z ot
600 PC

I don't have an electrical scheme and can't get rid of these alarms by means of resetting it.
Who can help in solving this problem?
