5.12.5.1 Setting SS1 with braking ramp monitoring
Requirement
You are online with STARTER or Startdrive.
Procedure with STARTER
To set the SS1 function with braking ramp monitoring, proceed as follows:
1. Select "[1] Safety without encoder with braking ramp (SBR)".
2. Press the "Safe stop functions" button.

3. The shutdown speed SS1 is a condition for the transition into the STO function.
4. If the ramp-down time (OFF3) in your application is less than 10 seconds, then leave the
delay time at its factory setting. If SS1 goes into a fault condition during the function test,
increase this value until the motor brakes normally without a fault.
If the ramp-down time (OFF3) is set to several minutes, you must extend the delay time to
several seconds in order to avoid any unwanted faults when selecting SS1.
