System Operation and Functions
2-13-5. Dynamic Muting
The Dynamic Muting function can configure a new muting zone while the MUTING state is enabled,
based on a result measuring a workpiece height for a certain period of time.
This materializes the safer Muting function with a limited muting zone adjusted according to a
workpiece height.
Usage example
This function cannot be used for an application in which a workpiece height gets larger after measuring
the zone as shown below.
Zone measurement start condition
After the muting start condition is satisfied and the full detection zone is muted, blocking a part of the
F3SG-SR causes the Zone Measurement to start.
Zone measurement
The Zone Measurement monitors the highest and lowest parts of a passing workpiece during the
dynamic muting measurement time Tdyn (3 s: Can be changed). (Void spaces in workpiece(s) are
ignored.)
Zone determination
A zone enclosed by the highest and the lowest parts of the workpiece is set as a new muting zone.
Configuring a dynamic muting allowable beam allows the muting zone to be expanded by the number
of allowable beams. Configuring a dynamic muting allowable beam prevents unintended line stop due
to swing of a workpiece, etc. (The factory default setting of the dynamic muting allowable beam is 1.)
