Commissioning
4.10 Safety Integrated commissioning
Requirements
The following requirements must be satisfied when using the "SBT" 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 will find information on possible encoder concepts in the "Safety Integrated" Function
Manual, Section "Notes on safe actual value acquisition with encoder system".
● 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.
Configuring the brake test via SCC
1. Select the "SBT via SCC" setting in the "Select SBT" drop-down list.
The interconnection of 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. For more detailed information, see:
"Communication via SIC/SCC (Page 251)"
2. Select the test settings in the "Brake 1" and "Brake 2" drop-down lists.
See "Features / Test configurations".
3. Set the following information in the input fields for Brake 1:
– Test duration (p10211[0])
– Holding torque (p10209[0])
– Position tolerance (p10212[0])
– Ramp time (p10209[0])
– Factor (p10210[0])
4. If you have set a 2nd brake, set the following information in the input fields for Brake 2:
– Test duration (p10211[1])
– Holding torque (p10209[1])
– Position tolerance (p10212[1])
– Ramp time (p10209[1])
– Factor (p10210[1])
5. Click "Save project" in the toolbar to save the changes in the project.
