Siemens Sinamics and Micromaster drive repair in Zambia
Sinamics G120, S120, Micromaster and Simovert drives, plus Simatic PLC and I/O cards, repaired and tested on our bench in Lusaka.

What we repair
Sinamics G120 and S120, Micromaster 420/430/440, Simovert drives, Simatic S7 PLC CPUs, I/O and communication cards, and the power and control boards inside them.
Typical faults
F-code trips that return after reset, blown power modules, failed gate drive boards, corrupted parameter sets and firmware, communication faults on PROFINET and PROFIBUS, and control supplies that collapse under load.
How the job runs
Unit logged and photographed on intake, diagnosed to component level with oscilloscopes, thermal imaging and power-quality instruments, fixed price quoted before work, functional test on completion, written report per serial number, 6-month workmanship warranty. Standard turnaround 5–7 business days; priority 48–72 hours under a maintenance agreement.
When the part is discontinued
We do not stop at "obsolete". We reverse-engineer the failed card, redesign it with components available today and build the replacement in Lusaka — the capability that put an HCS-designed board into a Lusaka Water pump station in February 2026, running since with zero failures.
Questions we are asked
Can you repair Siemens Micromaster and Sinamics drives locally?
Yes. We diagnose to component level and test the repair before the unit is returned, with a written report and 6-month workmanship warranty.
How long does the repair take?
Standard 5–7 business days from drop-off in Lusaka; priority 48–72 hours under a maintenance agreement. Importing a replacement typically takes 4–12 weeks.
What if the unit cannot be repaired?
You pay the assessment fee only and receive the diagnostic report — no repair fee for a unit we cannot save.
Is there a warranty?
Yes: 6 months (180 days) workmanship. Same-fault failure inside the window is re-repaired at no charge.
