Command Reference: Function Blocks
Section 6-5
In addition, the Muting function block has an override function to forcibly turn
ON the Output Enable signal without the condition for starting the muting
function being satisfied. (For example, when a detection object stops in the
light curtain’s detection zone, the machine can be operated to remove the
detection object.)
Any of the following four muting functions can be selected.
Note
In the explanation above, the muting sensors are ON when detection is per-
formed and OFF when detection is not performed.
Set Parameters
Note
The timer SV must be longer than the NE1A-series Controller’s cycle time.
Muting Mode
Application
Parallel Muting with 2
Sensors
This pattern is suitable for applications at a conveyor entrance.
Use this pattern when
two Retro-reflective Photoelectric Sensors are
set up as the muting sensors with intersecting detection zones.
Sequential Muting
(Forward Direction)
This pattern is suitable for applications at a conveyor entrance.
Use this pattern when four Through-beam Photoelectric Sensors are
set up as the muting sensors.
Sequential Muting
(both directions)
This pattern is suitable for applications at a conveyor entrance or exit.
Use this pattern when four Through-beam Photoelectric Sensors are
set up as the muting sensors.
Position detection
This pattern is suitable for applications in which muting is controlled by
a switch input.
