Forced Checking Procedure (Test Stop) - Siemens SINAMICS S120 Function Manual

Commissioning
6.8 Commissioning: Basic procedure
Note
Unique PROFIsafe addresses
You must ensure the unique assignment of the PROFIsafe address throughout the network
and the CPU.
• The fail-safe I/O of PROFIsafe address type 1 is addressed clearly by its fail-safe
destination address.
• The fail-safe destination address of the fail-safe I/O (drive units in this case) must be
unique for the entire fail-safe I/O throughout the network and the CPU (system-wide). The
fail-safe I/O of PROFIsafe address type 2, e.g. modules of the ET 200SP type, must also
be taken into account.
• Note also the corresponding documentation in the TIA Portal online help in Section
"SIMATIC Safety - Configuration and programming". (SDR001)
Without selection - configuration
As an alternative to controlling via terminals and/or PROFIsafe, there is also the option to
parameterize the "SDI" or the "SLS" functions without selection. In this case, the SDI
function is permanently active after POWER ON (with encoder) or becomes active after
switching on (without encoder) (see SDI (Extended Functions) (Page 59)). With the "SLS"
function without selection, there is no delay time and the function is permanently active after
POWER ON (with encoder), or it becomes active when switched on (without encoder) (see
SLS (Extended Functions) (Page 51)).
1. Select whether SLS or SDI should be selected permanently in the respective drop-down
list.

Forced checking procedure (test stop)

❒
Parameterize the settings for the forced checking procedure (test stop) in the "Test stop"
screen form.
To meet the requirements of the DIN EN ISO 13849-1 and IEC 61508 standards in terms of
timely fault detection, the converter must test its safety-related circuits regularly - at least
once a year - for correct functioning. The converter monitors the regular test of its safety-
related circuits that monitor the speed of the motor, and to safely interrupt the torque-
generating energy supply to the motor through the safe pulse suppression.
