Question Safely manage end of travel limits?

I'm still currently designing a linear actuator and was just considering the location of end of stroke limits. But this got me thinking about how others handle safeguarding an out of control actuator?
Usually when one actuator is extending another will be operating in the opposite direction but if one actuator was to stop for any reason (end of travel being one possible scenario), then what stops the other working actuators sending the rig into self destruct mode?
I'm guessing that the actuator and the frame needs to be designed to withstand the full force of the motor thus causing it to stall or blow a fuse before any mechanical damage?
Another thought I had was that all over travel limits could be wired back to the controller which could inhibit all drives at the same time and signal which actuator had failed?
Are there better ways to handle over travel?

@RandomCoder - good questions. I hadn't wondered about the endpoint switches but just about the whole getting actuators coordinated thing myself. Even before you hit ends of limit to shut something down, you will have had one actuator go way far out from its commanded position though.

I think it's OK but no experience with 6 DOF to say for sure. The way I think about it is your platform is ideally connected at three points to the actuators which connect at three points to the bottom frame. Since three points define a plane, any point can do pretty much anything and the plane of the platform will just tilt out of desired position. But since each point is made up from two actuators, I still think you are OK because the runaway actuator in extension or retraction will just cause the location of their shared point to pivot around the actuator end that isn't running away.

Might have it wrong and would need to think about it as the actuator connections move farther from each other, but I still think the platform will just tilt out of position and otherwise be OK. Each actuators' endpoint detection can probably just shut itself down but I think I'd shut it all down. Still might be in for a ride before it does shut down though.

I believe this scenario you mention is why the platforms aren't over constrained. If you had four actuators with each at the corner of a square or rectangle, if one runs away, it is then trying to bend the platform instead of just tilt it.

If you design your rig correctly then no combination of actuator positions should break anything. My limits also control the PWM, so that the actuator will stop driving in that direction when triggered. I do also have a panic button which will interrupt the controller data (tag block on the standard 1280 hardware).

I use 2 limit switches on each Actuator to stop before it gets to the end also a ES button and SMC3 limits too
