This machine started to give up this problem. When machine changes the tool, the tool arm will stop half way with the error TOOL NOT UNCLAMPED. air keeps blowing.. then if you press CE and start button, it would proceed with the tool change and proceed with the program. This would happen with every toolchange..
Action;-
Dismantled/inspected and assembled the belleville springs, cleaned everything.
Checked both limit switches on the Drawbar piston.
everything looks ok.
However by accident, when testing with the meter the lower microswitch during toolchange, if the meter is left connected, the tool change would proceed without a problem.
Then I bridged the lower microswitch with a Zener Diode, the machine would work, tool change works but it will skip blowing air in the spindle taper to clean and will not do spindle orientation.
I put M19 before each tool change and got round the problem this way. Machine seems to work ok but something is not right.
Somebody encountered anything like this? I do not want to leave it like this definitely.
I am suspecting something may be a problem with the swinging arm 30 POS tool-changer. Anybody has a schematic of how this works?
Thanks in advance.
