Forced Dormant Error Detection (Test Stop) Of The Cu310-2 - Siemens Sinamics S120 Function Manual

Commissioning
6.8 Commissioning CU310-2 using STARTER/SCOUT
Functions of this screen:
● Select an F-DI for functions STO, SS1, SS2, SOS, SLS, for the velocity limits (bit-coded)
of SLS (p10022 to p10028) as well as SDI (p10030 and p10031) and select SLP (p10032
and p10033).
An F-DI can be assigned several functions.
● Configuration of the "Safe State" signal (p10039)
A safety output signal "Safe State" can be generated for the drive from the following
status signals: STO active (Power_removed), SS1 active, SS2 active, SOS active, SLS
active, SDI positive active, SDI negative active, SLP active
The status signals of the individual functions (STO active, SS1 active, etc.) are ORed.
The "Safe State" signal can be assigned to the F-DO.
● Static selection/deselection of functions
– With "Statically selected", a safety function can be permanently selected.
– With "Statically inactive", a function can be permanently deselected. This setting is
6.8.4

Forced dormant error detection (test stop) of the CU310-2

Testing fail-safe inputs and outputs
Fail-safe inputs and outputs must be tested for fail-safety at defined time intervals (forced
dormant error detection or test stop). For this purpose, the CU310-2 contains a function
block that runs this forced dormant error detection (test stop) for the fail-safe output when
selected via a BICO source. Each time a forced dormant error detection (test stop) is
performed without error, a timer is started to monitor the time until the next required test.
After this time interval (p10003) has elapsed and every time the Control Unit is switched on,
the user is informed by the message A01774 that forced dormant error detection (test stop)
must be performed.
● 3 modes can be selected for testing the output (see following chapter).

Tes ting the sensors for the CU310-2
Unlike TM54F, the sensors connected to the F-DI of the CU310-2 cannot be tested as part of
forced dormant error detection (test stop). The user must cyclically test sensors connected to
the F-DIs. Then it is sufficient to actuate the particular sensor and to check the
corresponding function selection.
