The workpiece passed F3SG-RA’s detection zone
A workpiece has passed F3SG-RA’s detection zone. When the muting end wait time: T4 (1 s:
configurable) passes after the F3SG-RA is unblocked, the muting state is released.
 Installation Distance
Distances between muting sensors A1, B1, and F3SG-RA must be configured based on speed of a
workpiece.
Distance d1 between muting sensors A1 and B1 must satisfy Equations (1) and (2).
Distance d2 between muting sensor A1 and F3SG-RA must satisfy Equations (3) and (4).
Time t1 [ s ] to turn muting sensors A1 and B1 in this order is:
t1 = d1 / V . . . . . . . . . . . Equation (1) d1 [ m ] : Distance between muting sensors A1 and B1
V [ m/s ] : Approach speed of a workpiece
Time t1 in Equation (1) for F3SG-RA to enter muting state is within a range shown below:
T1min < t1 < T1max. . . . Equation (2) T1min [ s ] : Muting input time limit value (minimum)
T1max [ s ] : Muting input time limit value (maximum)
The values of T1
min
and T1
max
can be changed by the Configuration Tool.
Time t2 [ s ] for a workpiece to pass F3SG-RA’s detection zone after passing the muting sensor A1 is:
t2 = d2 / V . . . . . . . . . . . . Equation (3)
d2 [ m ] : Distance between muting sensor A1 and F3SG-RA
V [ m/s ] : Approach speed of a workpiece
Time t2 in Equation (3) must satisfy following condition:
t2 < T5 . . . . . . . . . . . . . . Equation (4) T5: Exit-only muting delay time
The value of T5 can be changed by the Configuration Tool.
Sensors must be installed so that person’s passing should not cause muting state.
