4.7 Service and Maintenance
It is required for PL d or SIL2 to conduct a functional test every 12 months to detect any failure or malfunction of the STO functional-
ity. For lower PL or SIL, it is a recommendation.
4.7.1 Performing Functional Tests
It is required to perform successful functional tests. If hardware faults are detected during a test, leading to situations where step 3–
5 and step 7 cannot be verified:
Immediately initiate the STO.
Replace the faulty unit and run a successful commissioning test before resuming normal operation.
Operation is not allowed with a faulty unit.
Repair is not allowed.
If a failure is found in the periodic test, it must result in a safe state. The drive cannot guarantee a safe state so the test must be
conducted in a way that secures a safe state, for example, via a safety PLC.
Procedure
Remove 24 V DC voltage supply at terminal 37.
Check if the LCP shows Alarm 68, Safe Stop or Warning 68, Safe Stop.
Verify that the drive trips the unit.
Verify that the motor is coasting and comes to a complete stop.
Verify that the motor cannot be started.
Reconnect 24 V DC supply to terminal 37.
If parameter 5-19 Terminal 37 Safe Stop is set to default value [1] Safe Stop Alarm, verify that the motor is not started auto-
matically and restarts only by giving a reset signal via bus, digital I/O, or [Reset] key.
