Our 4-Step Quality Verification Process
At Konmask.com, supplier trust is not a promise — it is a documented process. Every Siemens 6SE6440-2UD24-0BA1 unit is processed through the following verification steps before shipment:
- Source Authentication — Units are procured exclusively from authorized Siemens distributors or verified OEM surplus channels. Procurement records are retained for traceability.
- Physical Inspection — Serial number, label integrity, housing condition, and connector pins are inspected against Siemens factory standards. Counterfeit indicators are checked using reference units.
- Functional Power-On Test — Each drive is bench-tested: power-on self-test, parameter reset, and basic motor simulation to confirm firmware integrity and output response.
- Packaging & Documentation Check — Original or OEM-equivalent packaging, Siemens datasheet, and a Konmask inspection certificate are included with every shipment.
