Description of Safety Integrated functions
4.2 Safety Integrated Extended Functions
● In addition, in the "Safety Info Channel", status word S_ZSW1B.14 = 1 is set. This bit
corresponds to diagnostic parameter r9734.14.
● You can use p0890[1] to interconnect to an ESR integrated in the drive.
● SS2ESR has no effect on the "Setpoint speed limit effective" (r9733[0...2]). If SS2ESR is
enabled in p9501.4, then also a STOP E has no effect on r9733[0...2].

After the function has been selected, the delay time starts to expire - even if the function is
deselected during this time. In this case, after the delay time has expired, the SOS function
is briefly active. Afterwards, the drive may accelerate the motor back to the speed setpoint.

When selecting SS1, the drive brakes the motor along the OFF3 ramp and monitors the
speed using function SAM/SBR. Function STO becomes active when the motor is at a
standstill.
When selecting SS2, the drive also brakes the motor along the OFF3 ramp and monitors the
speed using the SAM function. Function SOS becomes active after time p9552.
