Lenze Drive Repair — i500, i700, 8400, and EVS/EVD Series
Lenze is a German drive and automation specialist whose frequency inverters, servo drives, and controllers are widely deployed in material handling, packaging, textile, and general machine building. Their product families — i500, i700, 8400 StateLine/HighLine/TopLine, and legacy EVS/EVD/ECS servo systems — provide solutions from simple speed control to high-dynamic servo applications. With a strong presence in European OEM machinery, Lenze drives are found in many intralogistics and packaging installations.
Common Lenze drive failures include IGBT power module degradation in higher-power units, electrolytic capacitor aging in DC link and control power supply sections, cooling fan failures, control board faults (processor issues, memory corruption, communication module failures), and braking chopper circuit problems. The 8400 series frequently develops SMPS (internal power supply) faults, while legacy EVS/EVD servo amplifiers are susceptible to resolver/encoder interface card failures and bus capacitor aging.
EFIXLAB provides comprehensive Lenze drive repair across all product generations. Our repair scope includes power stage diagnostics and IGBT module replacement, DC link capacitor bank renewal, control board component-level repair, communication interface testing (PROFINET, EtherCAT, PROFIBUS, CANopen), and cooling system overhaul. Legacy EVS/EVD servo drives receive particular attention to resolver interface circuits and aging capacitors throughout the feedback and control sections.
Lenze drive repair delivers substantial savings for facilities with large installed bases of Lenze equipment. Typical cost reductions of 35–60% versus new drive purchase make repair the economical choice, particularly for higher-power i700 and 8400 HighLine/TopLine units. For discontinued EVS, EVD, and ECS series, repair is essential to avoid costly drive system redesign and reprogramming. All Lenze drive repairs include motor load testing and our 12-month warranty.
