Safety Integrated Basic Functions
5.2 Safe Stop 1 (SS1, time controlled)
Safety Integrated
70 Function Manual, 05/2010, A5E03264275A
Prerequisite
The "Safe Torque Off" function must be enabled.
In order that the drive can brake down to a standstill even when selected through one
channel, the time in p9652/p9852 must be shorter than the sum of the parameters for the
data cross-check (p9650/p9850 and p9658/p9858).
The time in p9652/p9852 must be dimensioned so that after selection, the drive brakes to a
standstill.

The status of the "Safe Stop 1" (SS1) function is displayed using the parameters r9772,
