No. Description / commentsParameter
4
p9602 = 1
p9802 = 1
Enable the “Safe brake control” function
Enable “SBC” on the Control Unit
Enable “SBC” on the Motor Module
S The parameters are not changed until safety commissioning mode has
been exited (i.e. when p0010  95 is set).
S Both parameters are contained in the crosswise data comparison and must,
therefore, be identical.
S The “Safe brake control” function is not active until at least one safety
monitoring function is enabled (i.e. p9601 = p9801  0).

p9620 = “Value”
Terminal “EP”
Set terminals for “Safe standstill”
Set the signal source for “Safe standstill” on the Control Unit.
Wire terminal “EP” (enable pulses) on the Motor Module.
S Control Unit monitoring channel:
The following can be carried out if BI: p9620 is interconnected accordingly
for the individual drives:
– Select/deselect “Safe standstill”
– Group the terminals for “Safe standstill”
Digital input DI 0 ... DI 7 on the Control Unit can be used as a signal source.
S Motor Module monitoring channel:
By wiring the “EP” terminal accordingly on the individual Motor Modules, the
following is possible:
– Select/deselect “Safe standstill”
– Group the terminals for “Safe standstill”
Note:
The “Safe standstill” terminals must be grouped identically in both monitoring
channels.

p9650 = “Value”
p9850 = “Value”
Set the tolerance time for the SGE changeover
Tolerance time for the SGE changeover on the Control Unit
Tolerance time for the SGE changeover on the Motor Module
S The parameters are not changed until safety commissioning mode has
been exited (i.e. when p0010  95 is set).
S Due to the different runtimes in the two monitoring channels, an SGE
changeover (e.g. selection/deselection of SH) does not take immediate
effect. After an SGE changeover, a crosswise comparison of the dynamic
data is not carried out during this tolerance time.
S Both parameters are contained in the crosswise data comparison and must,
therefore, be identical. A difference of one safety monitoring clock cycle is
tolerated for the values.
