Commissioning the Fail-Safe Functions

Available fail-safe functions
● Safe Torque Off (STO)
● Safe Stop 1 (SS1)
● Safely Limited Speed (SLS)
Command source for fail-safe functions
As command source for the fail-safe signals STO, SS1 and SLS the fail-safe terminals (60 ...
63) and PROFIsafe can be used (see p9603 and p9803) simultaneously.
PROFIsafe address
To run PROFIsafe, the PROFIsafe address (P9810) must be set first. The default setting
(P9810 = 0) is an invalid address.
The PROFIsafe address must be changed in P9810 and in the higher level control system
(for example, HW Config in SIMATIC S7) otherwise fault F1640 will occur.
Note
Via terminals two of the three fail-safe functions (STO, SS1 and SLS) can be used. Via
PROFIsafe all three functions are available.
State of the fail-safe digital inputs
The state of the fail-safe digital inputs can be transferred as a PROFIsafe signal to the higher
level control unit as part of the PROFIsafe telegram (FDI0 via PROFIsafe, Bit 4, FDI1 via
PROFIsafe, Bit 5).
In the default setting the transfer is not active. Details see P9601 and 9801.
Commissioning parameters regarding fail-safe functions
Parameters regarding fail-safe functions can only be accessed on a Control Unit with fail-
safe functions, on a Standard CU this parameters are not available. For safety reasons
parameters are handled by pairs and stored on two separate processors (P1 and P2) within
the CU with fail-safe functions.
When commissioning of fail-safe functions is completed, checksums for each processor data
are created. These checksums are permanently compared. If they differ, the inverter initiates
a latched safe torque off (LSTO) state and stops the system.
Access to fail-safe parameters
The access level of the fail-safe function parameters is 3, therefore set P0003 = 3, when
using a BOP.
To enter the commissioning mode for fail-safe functions set parameter P0010 = 95.
