Is the TÜV sertification still valid for the STO, if service has been done to the ACS580 drive?

Eero Pyharanta, Global Product Manager

ABB's answer

Yes, assuming the proper service instructions are followed, genuine spare parts are used and the testing of the STO circuit is done according to the service instructions and the test report is stored to the Drives installed database (DIB) by the service producer.
