I have rescently started working with a ~1986 Baltec Brecker punch press with a siemens sinumerik system controller on it, unfortunately my employers have not been able to supply a user's guide and manual for the cnc controll that the machine operates with and given the age of the later its doubtfull that they'll bother looking for a spare one.

I cannot say what type of controller it is because there are no tags on it anywhere but from what I've searched over the net I have found it to be similar to the siemens sinumerik system 3M and 3T controllers for either a lathe or a mill, the only difference being that its a punch press and it lacks the spindle controlls on the panels, other than that its identical.

I am mostly interested in the description of the codes that the controller operates with so if anyone has any idea or better yet could point me to a manual for this I would be very greatfull.
