Note: In the construction with VD, the first functional check is automatically saved as the reference run. This is used as a comparison for all
subsequent functional checks under the same operating conditions

The values specified in the operating manual must be observed. The values must be determined according to ISO 14694.
4
The service life of the bearings is generally 20,000 h, but the actual service life can deviate considerably from this value depending on the
bearing load. The operating instructions provided by the motor manufacturer are available for download from the manufacturer’s website.
