Extended and Advanced Functions
The following is a description of how you commission the Safety Integrated Extended
Functions in Startdrive, using SS1 as an example. The screen forms shown here are
examples from the offline commissioning. To complete commissioning, you must
subsequently establish an online connection between Startdrive and the drive.

SS1 (Extended Functions)
Make the settings for the motor deceleration in the "SS1" screen form. The "SS1" function
brakes the motor, monitors the magnitude of the motor deceleration within specified limits,
and after a delay time or violation of a speed threshold, triggers the "STO" function.
