Ok, where to begin...
We have an Amada Pega 357 with a 58 station turret with dual auto indexers.
the startup procedure, involving homing X, Y, T and C axes works fine most of the time. But when I try to, for instance enter a command in MDI mode, it obeys X and Y commands, but either ignores T commands if the MDI block is the first action attempted or goes to random locations if the turret was rotated manually beforehand.
In manual, the tool change functions as expected: retracting the turret clamp, rotating to the next tool station, then reinserting the turret clamp.
In Automatic operation, if it moves at all, it usually ends up in a random location, usually between tool stations.
Most of the time, when the turret is instructed to move using MDI commands, it doesn't move, the two circuit breakers for it and the clamp engage inside the control box, next to them a relay lights up green, on the screen is displayed "01 EXEC MF/TF/EF"
and any subsequent attempt to move the turret or the index pin returns a "06 INTERLOCK" error, or alternatively, other times, the exact same sequence of events causes the same symptoms, but without any messages on screen.
Is the machine sentient and simply playing games with me or is this a familiar problem to anyone here?
