Hi. I have a "Mazak super quick turn 250 ms" yaer 1998. When i rotate the turret manually with the fwd/ccw button the turret works fine and tool positions is correct at display. But if i trying to change tool in mdi mode the turret start rotating with high speed and stops att wrong number. it sounds like it doesent clamp. i need to reset... then it clamp. I get alarm 272 and 221 I tried to shift the clamp/unclamp valves.. worked 3 times.
