Hello, on this occasion I have a problem with my 1998 vf4. The problem began with errors in the tool change. That is, when I ordered a tool change, the spindle was oriented first but in the middle of the operation it began to move in both directions. and again he was oriented.
The same thing happens when I press the orient button, the spindle moves to the orientation position but in an instant it turns back and forth consecutively.
Additionally, I realized in normal condition without commanding a spindle orientation, as soon as I hit reset to remove the alarms, I cannot move the spindle by hand, it is only possible by pressing the emergency button.
