Country: USA
Application: Robotics
Protection: Perimeter Guarding
Formula: D >V(t
S
− V = 63 in./sec.
− t
= 20 ms (FF-SPS4)
1
− t
= 200 ms (machine stop time; including response time of all interconnecting components,
2
such as relays, solenoids, brakes, etc.)
− C = 33.5 in. (USA)
− D
= 63 (0.020 + 0.200) + 33.5 in. = 47.36 in.
