Diff between Controlled Stop and Power Off Stop

Follow

Dear Ernesto,
In Controlled stop, the robot is stopped on the program path. This function is effective for a system where the robot can interfere with other devices if it deviates from the program path. In Controlled stop, physical impact is less than Power-Off stop. This function is effective for systems where the physical impact to the mechanical unit or EOAT (End Of Arm Tool) should be minimized. The stopping distance and stopping time of Controlled stop is longer than the stopping distance and stopping time of Power-Off stop, depending on the robot model and axis. Please refer the operator's manual of a particular robot model for the data of stopping distance and stopping time. 

Happy Learning :)

Thanks sarwat it was helpful. :)
