6.2.3.1 Introduction to the SS1 Function
The Safe Stop 1 (SS1) safety function monitors the motor deceleration and activates the STO(+SBC) function. Select the activation
settings of the STO(+SBC) function with the SS1 parameters.
The SS1 function can operate in one of the three monitoring modes:
Time monitoring mode
Time + zero speed monitoring mode
Time + zero speed + ramp monitoring mode
The SS1 function can activate the STO function:
When an application-specific time delay has passed (Time monitoring).
When the speed reaches zero speed (Zero speed monitoring).
