VFD Inverter Repair in Baku
VFD inverter repair in Baku — circuit board repair for frequency converters, motor drives and servo drives: burnt IGBT module, motor will not start, drive throws an error code.
Order
Send the make and model and describe the fault briefly. A video helps most — film the fault. Clear photos of the board help too.
Electronics repair for variable frequency drives (VFD), motor drives and servo drives. Danfoss, ABB, Yaskawa, Lenze, Schneider, Siemens. IGBT module replacement on three-phase industrial inverters, DC bus capacitors and circuit board repair.
How we work
Not every device can be repaired
Sometimes restoration is not possible: the chip is discontinued and no spare can be sourced, no donor board is available, the board is severely damaged by fire or liquid, or earlier repair attempts have left it beyond recovery. In such cases we explain the situation plainly and, where possible, suggest an alternative.
A variable frequency drive — the VFD, often called simply an inverter on the shop floor — controls motor speed and is one of the hardest-worked blocks in a plant. A burnt IGBT module in the power section, a failed current sensor and lost encoder feedback are the three faults we see most.
We work with Danfoss, ABB, Yaskawa, Lenze, Schneider and Siemens drives and replace IGBT modules on three-phase industrial inverters — the work is circuit board repair, not buying a new drive. On servo drives we additionally check the feedback path and the encoder input: when a motor judders or will not hold position, that is usually where the cause lies.
The essential rule in this group: replacing a burnt IGBT module is never enough on its own. If what burnt it — a fault in the gate driver, dried-out DC bus capacitors, a stopped fan or an insulation problem in the motor cable — is still there, the new module burns out just as fast. So we look for the cause in every case.
Devices we repair
Common faults we repair
- The IGBT module has burnt out, the drive will not start
- The motor will not run, the drive shows an error code
- Protection trips under load and the drive stops
- A failed current sensor gives wrong readings
- Loss of encoder feedback
- The servo motor judders and will not hold position
- DC bus voltage will not rise, or is too high
- The cooling fan has stopped and the drive overheats
- The keypad or panel does not respond
- Control over Modbus / the network drops out
- An earth fault is reported
- The braking resistor circuit does not work
Typical causes of failure
- An IGBT module punctured by load or by degraded cooling
- DC bus capacitors drying out
- Failure of the current sensor (shunt or Hall type)
- Damage to the encoder input and feedback circuit
- Overheating after the cooling fan stopped
- An insulation fault in the motor cable
- Failure of the optocoupler in the gate driver circuit
- A heatsink clogged in a dusty environment, reducing heat transfer
Brands and platforms we work with
How the repair works
- 01
Enquiry and first contact
Tell us about the fault on WhatsApp or Telegram. We review what you send and let you know whether the device fits the work we take on.
- 02
Acceptance and diagnostics
If we can take the device on, we confirm it in advance — do not ship it before you have our confirmation. Once it reaches the lab, diagnostics are completed within 48 hours (two working days).
- 03
Estimate and approval
You receive a report covering the cause of the fault, the estimated cost, spare-part availability and the timeline. Work begins only after you approve it.
- 04
Testing and handover
After the repair the device runs a minimum 24-hour load test. Once it proves stable in normal operation, we report the result and hand it over.
Diagnostics and pricing
Diagnostics is paid work — 10–50 AZN depending on the complexity of the board. If you have us carry out the repair, that amount is deducted from the final price. An exact repair price is given only after diagnostics and is agreed with you before any work starts.

Request a repair
Message us on WhatsApp or Telegram with the BRAND and MODEL of the device and describe the fault in as much detail as you can. A VIDEO helps most: record the fault and explain in your own words what happens. Also send clear photos of the device and, if accessible, of the circuit board from several angles. The more detail you provide, the faster and more accurate our answer.
