Starting point after referencing the machine:
- The cylinder for spindle support is extended
The spinport.comp component monitors the position of the axis.
- When the axis reaches position 900, the cylinder is retracted, and when the axis reaches position 1600, the cylinder is extended again.
position axis.x.pos-cmd > 900 Cylinder retracted
position axis.x.pos-cmd > 1600 Cylinder extended
What I need now is a check to see whether the cylinder is really retracted at the axis position between 900 and 1600 so that the axis can move through!For monitoring purposes, the cylinder is equipped with a reed contact when retracted.
Another factor that must be taken into account during monitoring is that the axis travels a certain distance during the time the cylinder is moving.The spindle support is at the axis position 1250 and I am traveling at a maximum speed of 4 m/s.
After thinking about it, also with your help, all that really needs to be checked is whether the cylinder is retracted between axis positions 1000 and 1500.
position axis.x.pos-cmd > 1000 and < 1500 ---> cylinder retracted
I think 100 mm in both directions should be enough for the cylinder movement!?!If that is the case, everything is fine. If the cylinder is not retracted, all axes must be stopped.
Now the only question is whether the check should be monitored in the spinport.comp file or in the HAL,and what could the code look like?
