Installation Guide
Commissioning test
There are 2 types of commissioning tests based on whether the STO parameter is configured for manual restart (M) or automatic restart
(A). For more information on the STO parameter, see the application guide.
If Parameter 7.2.1 Safe Torque Off Response = Fault - reset required, perform the steps marked with an "M".
l
If Parameter 7.2.1 Safe Torque Off Response = Warning - no reset required, perform the steps marked with an "A".

Type of test Commissioning steps
M/A Power on the frequency converter.
M/A Verify that no safety faults are present.
M/A Start the motor.
M/A Without interrupting the mains supply, remove the 24 V DC voltage supply to both STO input
terminals using the safety device.
M/A Verify that the motor coasts. This process can take some time.
M/A Verify that STO activated is shown on the control panel or in the event log.
M/A If the STO feedback is used, verify that STO is activated by checking the state of the STO Feed-
back.
M/A Reapply 24 V DC supply to both the STO input terminals.
M/– Verify that the motor remains in the coasted state and any connected relays remain activated.
M/– Send a reset signal via fieldbus, digital I/O, or the control panel.
M/A Verify that the motor starts up and runs within the original speed range.
