Hello everyone!
Milling machine Mazak vqc 15/40, controller Mazatrol M-32, 1990 year.
We faced with problem that linked with changing tools M06!!
Steps of changing tools :
1. Start command T04(preparing tool) M06(changing tool in spindle)
2. Machine send spindle in zero position 1. Home position of machine , use mechanical limit switch.
3. Spindle go down in zero position 2 by Z axis.
4. Opens the door tool box
5. Axis Y move in (+) direction in zero position 2, position for changing tool.
In this step axis Y move 5 mm and stop machine "Over travel axis +Y" ( In this case works optical switch that responsible for extreme stop servo motors and hydraulics system)
My opinion, command from optical switch must be ignored after step 4, but it's work and machine stop!!
We checked mechanical and optical switches they are work good. Mechanical system it's ok, without damages.
Can someone ideas what happened!!!
