How to secure falling off objects on emergency stop with the E-Pick ?

In the case of an emergency stop, there is a risk that your robot drop the object he has taken. This article will help you to avoid this problem. 

To secure the socket with E-pick, you must ensure that you always have the 24v supplying the gripper.
 
If you have a coupling with a cable directly connected to the controller, the gripper will not stop. If you plug the coupling into the wrist,  the 24V will be cut on the emergency stop and the vacuum will be lost.
 
However, in the event of a power outage, there is a risk of a falling window. 
 
The only way would be to plug it into an uninterruptible power source.
