8.4.2 Safe Stop 1 (SS1, time controlled)
General description
The "Safe Stop 1" function can be used to stop the drive in accordance with EN 60204-1,
stop category 1. The drive decelerates with the OFF3 ramp (p1135) once "Safe Stop 1" is
selected and switches to "Safe Torque Off" once the delay time set in p9652/p9852 has
elapsed.
CAUTION
When the SS1 (time-controlled) function has been activated through the parameterization
of a delay in p9652/p9852, it is no longer possible to select STO directly via terminals.
