Stopping Distances and Times
The following graphs present information required by Clause 7.2 n) of ISO 10218-1. This
information should be used to calculate the safe distance needed when designing and
installing safeguarding devices.
The graphs show the time elapsed and distances traveled between the initiation of a stop sig-
nal and the cessation of all robot motion.
For stop category 1, the stopping time and distance values depend on the speed, load, and
extension of the robot, stated for 33%, 66% and 100% of the maximum payload (5.5kg). Data
provided is for the three joints of greatest displacement (J1, J2 and J3).
NOTE: Where lines overlap (and may not be visible) differences are not sig-
nificant.
