Ss1 (Time Controlled) Without Off3 - Siemens Sinamics S120 Function Manual

● When SS1 is selected, the drive is braked along the OFF3 ramp (p1135) and STO/SBC is
Note
So that the drive is able to travel down the OFF3 ramp completely and any motor holding
brake present can be applied, the delay time should be set as follows:
• Motor holding brake parameterized: Delay time ≥ p1135 + p1228 + p1217
• Motor holding brake not parameterized: Delay time ≥ p1135 + p1228
● The selection is realized through two channels - however braking along the OFF3 ramp,

● The Basic Functions or STO are enabled via terminals and/or PROFIsafe.
● In order that the drive can brake down to a standstill even when selected through one

automatically initiated after the delay time has expired (p9652/p9852).
After the function has been selected, the delay timer runs down – even if the function is
deselected during this time. In this case, after the delay time has expired, the STO/SBC
function is selected and then again deselected immediately.

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). Otherwise the drive will coast down
after p9650 + p9658 have elapsed.
