Safety Integrated Basic Functions
5.2 Safe Stop 1 (SS1, time controlled)
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.
Status for "Safe Stop 1"
The status of the "Safe Stop 1" (SS1) function is displayed using the parameters r9772,
r9872, r9773 and r9774.
Alternatively, the status of the functions can be displayed using the configurable messages
N01621 and N30621 (configured using p2118 and p2119).
