Safe operating stop monitoring
The
Safe operating stop monitoring
function (SOS-M) monitors whether the stop position
remains within a configured tolerance window. Safe operating stop monitoring is activated
within a rising edge at the start input. It remains active until the value is outside the toler-
ance band. The function can be retriggered at any time by a rising edge at the start input.
As a result, the current position can be used at any time as the start point for the monitoring
function.
In PNOZmulti Configurator 3 elements SOS-M can be configured per axis (with units < Ver-
sion 2.0 only 1 element can be configured).
Please note:
This monitoring function cannot be used in conjunction with 2 proximity switches because
position detection is not possible.
WARNING!
Potential loss of safety function with a tolerance value >24,900,000 in-
crements!
The following applies when using a PNOZmulti Configurator
Version <10.0
:
If a tolerance value >24,900,000 increments is configured in the PNOZmulti
Configurator, the monitoring function will no longer be evaluated correctly.
Depending on the application, serious injury or death may result.
Make sure that a tolerance value <24,900,000 increments is configured.
From Version 10.0 of the PNOZmulti Configurator, the feasibility of the
value will be checked automatically.
