ACS380 repair and refurbishment
The ACS380 is a compact machinery drive designed for OEM integration, covering 0.25 kW to 22 kW. Its compact format and integrated safety make it popular in machine tool and conveyor applications — and when it fails, component-level repair avoids disruption to the wider machine design.
Common ACS380 faults we fix
-
Power stage IGBT fault causing overcurrent trips on startup — often triggered by a supply transient or motor winding degradation
-
DC bus capacitor failure resulting in undervoltage alarms or insufficient DC bus voltage during acceleration
-
Output relay failure causing incorrect switching on relay output terminals used for motor contactors or alarms
-
Internal power supply faults causing the drive to fail to power up or exhibit intermittent resets

ACS380 repair FAQs
Can you repair an ACS380 that won't power up at all?
Yes. A drive that fails to power up is often caused by an internal fuse, power supply rail fault, or rectifier issue. We carry out a bench diagnostic to identify the fault and quote accordingly.
My ACS380 is installed in an OEM machine — can you repair without replacing the whole unit?
Yes. Component-level repair is designed precisely for OEM applications where replacing the whole drive would require panel redesign or re-wiring. We return the same unit, repaired and tested.
