Example 3 :ANSI/RIA R15.06-1999
Safety distance calculation according to ANSI/RIA R15.06-1999 (in a case where the detection zone
is orthogonal to the direction of approach)
Formula S = [K x (Ts + Tc + Tr)] + Dpf
S : Safety distance (mm)
K : Approaching speed of the body or the part of body into detection zone (= 63 inch/s)
Ts : Final stop time required when stop control is issued to machine (s)
Tc : Maximum response time of machine's control system (s)
Tr : Maximum response time of the SL-V and its interface (s)
Dpf : Additional distance (mm) from the approach factor as in the following figure. This value varies
depending on the SL-V detection capability.
ANSI/RIA R15.06-1999 establishes K = 63 inch/s (= 1,600 mm/s) as a minimum speed.
