Hysteresis - Unipulse F320 Operation Manual

6-3. Hysteresis

The Hysteresis function provides a range of high/low limit comparison off.
Usually the high limit comparison is turned on when the indicated value is above
the high limit value and turned off when below. If you set a hysteresis range, the
comparison is turned off when the indicated value is below the high limit value
by the hysteresis setting. This is effective in preventing chattering caused when
signals are slightly varying （vibrating) .
〈Comparison conditions〉
• High limit
ON conditions : Indicated value > High limit value
OFF conditions : Indicated value <= （High limit value - Hysteresis set value）
• Low limit
ON conditions : Indicated value < Low limit value
OFF conditions : Indicated value >= （Low limit value + Hysteresis set value）
