Schneider ATV320 repair and refurbishment.
Component-level repair for the Schneider ATV320. Bench diagnostics, engineer-led, safety functions verified before return.
ATV320 repair and refurbishment
The ATV320 is Schneider Electric's current compact drive replacing the ATV312 in new installations. It covers 0.18 kW to 15 kW and includes integrated safety functions (STO, SS1). Component-level repair avoids the need to redesign the safety circuit integration when a drive requires service.
Common ATV320 faults we fix
-
Power card faults causing overcurrent or earth fault trips — often triggered by a supply transient or motor insulation fault
-
Internal circuit faults causing stops without an external signal — a known failure mode on ATV320 units in high-cycle applications
-
DC bus capacitor degradation on drives used in high switching-duty applications such as conveyor systems
-
Internal fuse failure following a downstream wiring short circuit, preventing the drive from powering up

ATV320 repair FAQs
My ATV320 has stopped with no external signal — is this a drive fault?
Yes, internal circuit failure is a known ATV320 fault mode. We carry out a bench diagnostic to confirm whether the issue is in the internal circuit or related wiring before advising on repair.
Can you repair an ATV320 that will not power up?
Yes. A drive that fails to power up is often caused by an internal fuse, pre-charge circuit fault, or power supply rail failure. We carry out a bench diagnostic to identify the root cause.
