Functional test Testing to determine whether the unit is working properly and to identify any specific issues​

Measurements Taking measurements based on Lenze specifications for the respective unit​

Inspection and repair happen in a single service step – any damaged or worn components are replaced exclusively with genuine Lenze parts. You benefit from up to 24 months of warranty on replaced parts, save costs compared to a replacement unit, and conserve resources at the same time.​
