Completion Of The Certificate - Siemens SINAMICS G120 CU240B-2 Operating Instructions Manual

Functions
7.10 Safe Torque Off (STO) safety function
No.
2.
Switch on the motor (ON command).
3. Ensure that the correct motor is running.
4. Select STO while the motor is running
Note: Test each configured activation, e.g. via digital inputs and PROFIsafe.
5. Check the following:
If a mechanical brake is not available, the motor coasts down.

A mechanical brake brakes the motor and holds it to ensure that it remains at a standstill.
The inverter indicates neither faults nor alarms for safety functions.

The inverter indicates:

"STO is selected" (r9773.0 = 1).
"STO is active" (r9773.1 = 1).
6. Deselect STO.
7. Check the following:
The inverter indicates neither faults nor alarms for safety functions.

The inverter indicates:

"STO is not selected" (r9773.0 = 0).
"STO is not active" (r9773.1 = 0).
The inverter is in "Closing lockout" state (p0046.0 = 1).

8. Switch the motor off (OFF1 command) and then on again (ON command).
9. Ensure that the correct motor is running.

Completion of the certificate

Document your machine's data for each drive based on the following specifications.
Parameters of the safety functions
The function test does not detect all faults in the parameter assignment of safety functions,
e.g. forced dormant error detection time or filtering time of fail-safe inputs. Therefore, check
all parameters once more.

Checksums of the safety functions
The inverter calculates checksums across all parameters and safety functions. The
parameters of Basic Safety and Extended Safety have their own checksums.
When you change the safety function settings, the inverter calculates new checksums. This
means that subsequent changes in your machine can be tracked.
