Siemens Sinamics S120 Function Manual page 133

Requirements
The following preconditions must be satisfied when using the "Safe Brake Test" function:
● The Safety Integrated Extended Functions must be enabled; also available for the Safety
Integrated Extended Functions without selection.
● Safe Brake Control must be enabled when testing a brake controlled by SINAMICS
(motor holding brake).
● Safety Integrated Extended Functions with encoder have been enabled.
You can find information about possible encoder concepts in Chapter "Notes regarding
safe actual value sensing using an encoder system (Page 147)".
● Speed control with encoder (p1300 = 21).
SBT is not possible with encoderless speed control (e.g. vector V/f control) and torque
control. In this case, alarm A01784 is output.
Enabling the SBT function
To enable the Safe Brake Test function, proceed as follows:
● Enable the Safe Brake Control (SBC) function when using an internal motor holding
brake: p9602 = 1.
● Select the SBT selection type with parameter p10203:
– = 0
– = 1
– = 2
● Check the motor type; the following must apply: p10204 = r0108.12
Parameterizing the test sequences
For testing brake 1 [index 0] or 2 [index 1], initially, those values must be entered, which
apply to both test sequences:
● Brake type (p10202[0,1])
– = 0 (≙ block)
– = 1 (≙ test motor holding brake)
– = 2 (≙ set external brake)
● You define the holding torque of brakes using p10209.

Selection of SBT via SCC
Selection of SBT via BICO
Selection of SBT on forced dormant error detection (test stop)
This must be set if one of the brakes is either not available or is not to be tested.
Here, in addition p1215 must be set to = 1
