After starting the machine and passing through reference points, the MDI does not execute command M 03 / M 04 / (which mean rolling respectively clockwise and counterclockwise) and M 19 / spindle orientation /. Also, the tool holder, which is situated in the spindle, can not be unlocked even though the hydraulic system works.
Otherwise, the movements on the XYZ axes in the same MDI mode are executed.
The management system is Fanuc 6M-B
