10.11.1Error reaction with function specific SS1 time for the Safety function "SLI" and the following
function "SOS"
With the software extension SAF-002/3 and with the SAF module configuration software
ProSafePara from version V1.1.0.0 onwards for every safety function a function-specific
SS1 time can be parameterized:
Figure 36: P216.005: SS1 time for the safety function „SLI“
This setting option applies to the following function SOS (an individual error can occur
during the following function SOS).
This time always acts as a delay if an individual error occurs.
This is supposed to allow the drive to drive down a brake ramp before the STO is
activated.
The following individual error can occur at the function "SLI" and the "following function
SOS":
m
Switchover to a data set which was not set
m
There is no encoder connected
m
Encoder standstill time extended
m
Exceeding the tolerance window
If a value in P216.005 is parameterized greater than zero, STO is not immediately carried
out if an individual error occurs, but at first the parameterized time of this function is
processed. An automatic signalization to the controller is connected if the error occurs.
Thereby, the drive error 1066 "SS1 stop forced by SAF module" is initiated.
The related error reaction must be parameterized in the controller (refer to
"Parameterization of the error reaction" and SS1 Stop Time" in
Z
chapter 10.4.1
–
).
Example:
During the process of the function "SOS" the individual error "Exceeding the position
range" occurs. In
Z
Figure 35

on page 78 this case is shown. Thereby, the time period
"SS1" accords to the time parameterized in P216.005 before "STO" is carried out.
10.11.2Operating principle of SLI and description of the transition SLI ->STO
After the safety function SLI was activated the current position is saved as SOS home
position in the safety module. After expiration of the SOS hold time an incremental jog can
be released by a switch. The drive can freely move within the released incremental jog.
If the switch is operated again during the activated incremental jog then the safety module
