The following diagram shows the characteristic of the safe output signal SSM when the
hysteresis is active:
SSM -Output signal
Figure 8-9
Note
When "hysteresis and filtering" is activated with output signal SSM, a time-delayed SSM
feedback signal occurs for the axes. This is a characteristic of the filter.
