Enables the Safe Brake Control function
Enables SBC on the Control Unit
Enables SBC on the Motor Module
● The parameters are not changed until the safety commissioning mode has been exited (i.e.
when p0010 is set ≠ 95).
● Both parameters are included in the crosswise data comparison and must therefore be set to
identical values.
● The Safe Brake Control function only becomes active if at least one safety monitoring function
is enabled (i.e. p9601 = p9801 ≠ 0).
Enable Safe Stop 1 function
Enables SS1 on the Control Unit
Enables SS1 on the Motor Module
● The parameters are not changed until the safety commissioning mode has been exited (i.e.
when p0010 is set ≠ 95).
● Both parameters are included in the crosswise data comparison and must therefore be set to
identical values.
● The Safe Stop 1 function only becomes active if at least one safety monitoring function is
enabled (i.e. p9601 = p9801 ≠ 0).
Set terminals for Safe Torque Off (STO)
Set the signal source for STO on the Control Unit
Connect terminal "EP" (enable pulses) on the Motor Module
● Control Unit monitoring channel:
By appropriately interconnecting BI: p9620 for the individual drives, the following is possible:
– Select/deselect STO
– Grouping the terminals for STO
– Digital input DI 0 ... DI 7 on the Control Unit can be used as a signal source (NCU). DI 0 ...
DI 3 (NX).
● Motor Module monitoring channel:
By appropriately connecting the "EP" terminal on the individual Motor Modules, the following is
possible:
– Select/deselect STO
– Grouping the terminals for STO
Note:
The STO terminals must be grouped identically in both monitoring channels.
Set F-DI changeover tolerance time
F-DI changeover tolerance time on Control Unit
F-DI changeover tolerance time on Motor Module
● The parameters are not changed until the safety commissioning mode has been exited (i.e.
when p0010 is set ≠ 95).
● Due to the different runtimes in the two monitoring channels, an F-DI changeover (e.g. selection/
deselection of STO) does not take place simultaneously. After an F-DI changeover, dynamic
data is not subject to a crosswise data comparison during this tolerance time.
● Both parameters are included in the crosswise data comparison and must therefore be set to
identical values. A difference of one safety monitoring clock cycle is tolerated for the values.
