t
1
: Activation of the monitoring function SS2-M
t
2
: Standstill detection limit value for automatic SOS reached, monitoring of
standstill position (SOS) is activated
t
3
: Standstill position outside of tolerance window, safety function "Safe
torque off" (STO) is activated
t
Delay
: Set delay time for controlled braking of motor
Hysteresis
A hysteresis can be configured for the monitoring functions. This prevents the outputs from
bouncing if there are fluctuations around the response value. The hysteresis takes effect
when the output is switched on.
