Component-level repair for the Siemens SINAMICS V20. Bench diagnostics, engineer-led, no fix no fee.
SINAMICS V20 repair and refurbishment
The SINAMICS V20 is Siemens' current entry-level compact drive, replacing the Micromaster 420 in new installations. Available from 0.12 kW to 15 kW, it is popular for simple pump, fan, and conveyor applications. Despite its compact size, component-level repair is viable for production-critical uses.
Common SINAMICS V20 faults we fix
-
Power stage failure presenting as overcurrent or earth fault alarms on startup — often triggered by a supply transient or motor winding fault
-
Keypad and display failure in installations where the drive has been operated frequently or in poor environmental conditions
-
Internal connector and PCB track damage from vibration in machine-mounted installations
-
DC bus capacitor failure on drives used in applications with frequent start-stop cycles or poor supply quality

SINAMICS V20 repair FAQs
Is it worth repairing a SINAMICS V20 given its relatively low new cost?
For production-critical applications, the key factor is downtime rather than component cost. Repair is often faster than procurement and recommissioning, especially where custom parameterisation is involved.
My SINAMICS V20 powers up but immediately shows a fault — can you identify why?
Yes. An immediate trip at power-up is typically caused by a DC bus or rectifier fault, or occasionally a control card issue. We carry out a bench diagnostic to confirm the root cause.
Can you repair a V20 that has suffered vibration damage?
Yes. Vibration damage to PCB tracks and internal connectors is repairable in many cases. We inspect the full board assembly and carry out rework where required.
