4.3 Safety Integrated Advanced Functions
Executing a forced checking procedure (test stop)
Forced checking procedure (test stop) can be executed at the following points in time:
1. Forced checking procedure (test stop) can be initiated application-specifically and can
therefore be executed at a time that suits application requirements.
This functionality is implemented by means of a single-channel parameter p9705, which
can be wired via BICO either to an input terminal on the drive unit (Control Unit) - or to a
bit of any arbitrary PZD.
In addition, it is possible to select the test stop via the Safety Control Channel (see
Chapter "Safety Info Channel and Safety Control Channel (Page 251)").
– p9559 SI Motion Forced checking procedure timer (Control Unit)
– p9705 BI: SI Motion test stop signal source
– r9723.0 CO/BO: SI Motion diagnostics signals integrated in the drive
If the test stop is executed as described, the action does not require a POWER ON. The
acknowledgment is set by canceling the test stop request.
2. Forced checking procedure (test stop) can be automatically executed at POWER ON.

Functions as well as an automatic test of the F-DO for the CU310-2, set p9507.6 = 1.
When testing the F-DO of the CU310-2, you must parameterize p10042 and activate
the test in p10046.
