SINAMICS S120 Fail-Safe Drives
Description
Enter the adjacent values in
the "Safe stops" screen
form.
The delay time SS1 ->
pulse cancellation (p9556)
must be selected so that
when the drive decelerates
from the maximum speed of
the application down to
standstill (zero speed), this
time is not exceeded.
The value of this parameter
is, among other things, de-
pendent on the load mo-
ment of inertia. The shut-
down speed SS1 (p9560) is
set to n = 0/min.
In the screen form "Safely
limited speed (SLS)" - enter
the maximum limit speed
(limit speed: when the
safety door is opened, the
speed that is still permissi-
ble) Only stage 1 is used for
the speed monitoring func-
tion. Further, the stop re-
sponse – that is initiated
when the limit value is ex-
ceeded – should be se-
lected.
The drive speed must be
below the limit value
n_max. within the delay
time "Select SLS -> SLS
active" (p9551),
Enable/activate the safety
functions.
