Directional reversal of a cam with hysteresis
The table illustrates the reaction to directional reversal. A distinction must be made between
the reaction of position- and time-based cams. The effective direction of the cam is positive.

The hysteresis will be set when a directional
reversal is detected. The cam is deactivated
immediately when the hysteresis range is
violated.
The cam always remains active for the duration
of the assigned activation time.
