5 repair services for fast recovery and long-term operational reliability​

Lenze repair services offer a range of options tailored to your exact needs—including inspection, basic repair, and premium repair, all backed by up to 24 months of warranty. If a basic or premium repair isn't possible, we offer emergency repair as an alternative. These services also include overhaul and modifications where needed, ensuring your equipment is optimally adapted to changing operating conditions and environmental factors. And if time is tight, all repair services are also available as an express option.​

Inspection​

Catch technical deviations early to prevent further damage​

Through a structured inspection, we systematically assess the condition of your unit – from visual checks to fault diagnosis. You'll receive a clear service report with actionable recommendations, giving you a reliable basis for your next maintenance and investment decisions.​

Inspection​

Inspection refers to the technical review and functional check of the complete unit and its components, to determine what issues are present and which parts may need to be replaced or repaired. ​ ​

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​

Fault diagnosis Analyzing error messages or codes displayed by the unit to determine the root cause of the issue​

Quick fixes for minor faults — get your equipment back up and running fast​

With basic repair, we resolve minor, acute faults quickly and precisely, getting your equipment back up and running fast. 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.​
