Description of Safety Integrated functions
4.2 Safety Integrated Extended Functions
Enabling the SBT function
To enable the Safe Brake Test function, proceed as follows:
1. Enable the Safe Brake Control (SBC) function: p9602 = 1.
2. Select the SBT selection type with parameter p10203:
– = 0
– = 1
– = 2
3. Check the motor type; the following settings must apply: p10204 = r0108.12
Parameterizing the test sequences
For testing brake 1 [index 0] or 2 [index 1], initially enter those values which apply to both
test sequences:
● Brake type (p10202[0,1])
– = 0 (≙ block)
– = 1 (≙ test motor holding brake)
– = 2 (≙ test external brake)
● You define the holding torque of brakes using p10209.
● Test torque ramp time p10208[0,1]
Within this time, before starting the test sequence, the test torque is ramped up. And at
the end of the sequence, it is ramped down again within this time.
Note
When testing an external brake, whose mechanical design exhibits backlash (e.g. if there
is a gearbox located between the motor and external brake), it can make sense to extend
the ramp time (p10208) when ramping up and ramping down the test torque.
● The parameters for the telegram extension relevant for SCC/SIC can be performed
automatically by setting p60122 = 701. However, the telegram extension must have been
previously created. More detailed information on this can be found in Chapter "Safety Info
Channel and Safety Control Channel (Page 251)".

Selection of SBT via SCC
Selection of SBT via BICO
Selection of SBT for forced checking procedure (test stop)
Make this setting if one of the brakes is either not available or is not to be tested.
For this setting, set p1215 = 1 in addition.
