Operating Guide
6.9.3 Commissioning Test
EN IEC 61508, EN IEC 62061, and EN ISO 13849 require that the final assembler of the machine validates the operation of the safety
function with a commissioning test. The tests for the configured safety functions are described in the commissioning report gener-
ated by the MCT 10 safe plug-in.
The commissioning test must be performed in the following cases:
• At initial start-up of the safety option.
• After any changes related to the safety function (wiring, components, parameter settings, and so on).
• After any maintenance work related to the safety function.
The commissioning test for systems with safety functions is focused on:
• Validating the functionality of safety monitoring and stop functions configured in the drive system.
• Correct selection of the safety option parameter values.
• Examining the response of specific monitoring functions to the explicit input of values outside tolerance limits.
Perform the commissioning test on the basis of the risk analysis. Adhere to all applicable standards and regulations.
Ensure that the following preconditions are met:
• The drive is wired properly. For more information about wiring, see chapter Installation.
• All safety equipment such as protective monitoring devices, light barriers, or emergency stop switches are connected and ready
for operation.
• All motor parameters and command parameters are set correctly in the drive.
6.9.3.1 Performing the Commissioning Test
Procedure
1.
Use MCT 10 set-up software to generate the commissioning test report.
2. Follow the test sequence in the report to ensure proper functioning of the safety option.
3.
Document each individual step of the test.
4. Note the checksum of the safety option parameters in the records.
5.
Do not release the system unless it has successfully passed all individual steps of the test.
6. Restart the drive and check that the motor runs normally.
6.9.4 Commissioning Test Report
After some operations, for example LCP copy of safe parameters, a commissioning test is required. Follow and approve the test
sequence according to the commissioning test report.

Safety functions Test procedure
STO 1. STO function must be inactive:
• Via digital input.
• Via PROFIsafe.
• Check the STO circuit connections against the circuit diagram.
2. No safety faults and alarms.
3. Run the drive.
4. Ensure that the correct drive is running.
5. Trigger STO while the drive is running.
6. Check the following:
• The drive coasts to zero speed.
• The motor is braked and stopped by the mechanical brake (if available and configured).
• Warning 68 is displayed.
