The SS1 delay function does not monitor the stopping of the drive. The time relevant for safety allows the drive to stop before
Safe Torque Off is activated, and ensures that the system is stopped before Safe Torque Off is activated.
If a fault occurs, the drive does not come to a stop. It coasts after the time delay regardless of the speed of the drive.
Using SS1 delay may result in the motor still spinning when Safe Torque Off is activated.
The risk analysis for the machine must indicate that this behavior can be tolerated.

An interlock may be required.

Parameters for Safety Functions
Description
Specifies the safe digital input,
which can be associated to the
activation of the safety func-
tion.
The maximum time of the stop
procedure.
The time to ignore the decel-
eration after the activation of
SS1.
The time the speed has to be
within the limits before acti-
vating the final state (early ac-
tivation).
The limit for the deceleration.
a_SS1 = 0 means "No decelera-
tion monitoring".
The limit within the speed is
accepted as 0.
