SINAMICS S120 Fail-Safe Drives

Especially note the following settings for Drive 2:

Enter the adjacent values in the

"Safe stops" screen form.

Select the delay time SS1 → Pulse

cancellation (p9556) so that when

the drive decelerates from the maxi-

mum speed of the application down

to standstill (zero speed) this time is

not exceeded. The value of this pa-

rameter depends among other things

on the load moment of inertia.

Set the shutdown speed SS1

(p9560) to n = 0/min.

In the screen form "Safely limited

speed" - enter the maximum limit

speed, which is permissible when the

safety door is open. Only use stage 1

for the speed monitoring function.

Further, the stop response – that is

initiated when the limit value is ex-

ceeded – should be selected.

The drive speed must be below the

limit value n_max. within the delay

time "Select SLS -> SLS active"

(p9551).

To save all of the changes, click on

"Entire project".

You can operate the drives when the Emergency Stop has been deselected

if you have performed the safety commissioning for all drives, then.
