Spindle safety

[JesseH]

As a safety we monitor flow into the spindle via WAITDI"flow" as stop state, ? Can I ....... IF DI"flow" =,0; THEN SetDO "spindle_on",0;......now if we loose flow the spindle will stop and the robot will be in stop state

Do you mean as a stop state - robot program only will stop?
In the second example do you want to stop the robot and the spindle to stop at the same time when you check the flow?

Both checks seem only to check the flow at some point in the logic before the robot starts to move. Probably a TRAP routine would be better suited if you need to constantly monitor a signal while the robot is executing a program.

Yes I want to monitor flow while we're running. If the spindle looses coolant it will burn up, so if the spindle stops at any time durning the run i want the robot to as well, protecting the work piece....? How would that look as a trap if i use:
Waitdi "flow",1; to check flow
Waitdi "pressure",1; to check pressure
SetDO "spindle_on",1; to turn on spindle
IF DI "flow"=,0; THEN SetDO "spindle_on",0;
IF DI "pressure" =,0; THEN SetDO "spindle_on",0;
…….…program.………
