2-16. Reduced Resolution

F3SG-RA Series
F3SG-RE Series
2-16-1. Overview
The reduced resolution function prevents the safety output to turn off by an object moving in a
detection zone. With this function, an object with a size of 1 to 3 beams can be ignored by changing a
detection capability size. Unless the number of continuously blocked beams exceeds the setting (1 to 3
beams), the total number of blocked beams has no limit. The response time remains the same even
when the detection capability is changed.
The difference from the Floating Blanking is that the Reduced Resolution keeps the safety outputs ON
even when an object is present discontinuously.
Refer to 2-1. Combination of Functions for more information on the use in conjunction with other functions.
The Reduced Resolution is not available for the F3SG-RE.
Example:
The F3SG-RA does not turn the safety outputs OFF when the number of blocked continuous beams is 3 or more. (Fig. 1)
The F3SG-RA does not turn the safety outputs OFF when the number of blocked continuous beams is 2 or less. (Fig. 2)
The F3SG-RA does not turn the safety outputs OFF when there are some combinations of continuously blocked beams
in a detection zone but the number of the continuously blocked beams of each combination is 2 or less. (Fig. 3)
The F3SG-RA does not go to the Lockout state and does not turn the safety outputs OFF even when an object has been
removed from the detection zone. (Fig. 4)
Multiple combinations of beams are blocked
(Each combination consists of 2 or fewer beams)
