Scope of this technical record
Use this record when an ACS800 2340 case needs a controlled decision about IGBT/module repair, donor module sourcing, AGDR relationship or modernization.
This record is for evidence collection and service decision support. Power-module inspection and any test work must be performed by qualified personnel under safe, documented procedures.
ACS800 IGBT module evidence route
The record converts a destructive output-stage event into a repair, donor-unit or modernization decision.
A module request must prove the boundary
A request that says only 'ACS800 2340, need IGBT' is not sufficient for a reliable service decision. The record must show the installed type code, module label, phase-leg evidence, external output proof, AGDR relationship and whether any previous module has already failed.
A donor module or repaired module can be the right decision, but only when the initiating condition and driver boundary have been addressed. Otherwise the donor part becomes the next failed part.
Repair decision matrix
The matrix below helps convert a destructive output-stage case into a clear service request.
IGBT output-module decision
| Evidence package | Likely decision | Do not skip |
|---|---|---|
| External fault proven | Repair field condition first | Drive-side conclusion |
| Static module damage plus driver clear | Module repair or donor match | Compatibility and staged proof |
| Driver abnormal or repeat failure | AGDR plus module route | Original cause review |
| Scarce parts and repeated failures | Modernization review | Evidence of why repair is risky |

Technical basis and reference documents
This is an independent editorial technical reference. Original manufacturer documentation remains controlling for installation, repair and commissioning decisions.
OEM basis for ACS800 SHORT CIRC 2340, PPCC LINK 5210, FAULTED INT INFO and INT SC INFO context.
OEM basis for hazardous-drive safety, cabinet structure, power-module and control/interface hardware context.
Public field discussion showing why 2340 cases can involve AGDR/module evidence, vibration, dust and repeat-failure conditions.
Linked circuit records
Maps SHORT CIRC evidence from fault timing and localization into U/V/W phase-leg inspection, IGBT module condition, driver relationship and output-stage repair boundary.
Routes ACS800 2340 cases through motor cable, motor winding, terminal box, output accessories and output contactor evidence before internal power-stage repair is assumed.
This path separates control/interface command, AGDR driver health, isolated driver supply, gate output, IGBT phase-leg condition and motor-output evidence after an ACS800 SHORT CIRC event.
Turn this record into a qualified service request
A repair decision is much more reliable when the request includes the exact identity of the drive, the first fault evidence and the machine condition when the symptom appeared.
- Complete drive type code / MLFB or nameplate model
- Fault code, fault value and first event before reset
- When the event appears: power-up, enable, ramp, run, decel or stop
- Motor/cable connected or isolated during the symptom
- Visible board, option-card, module and connector identifiers
- Previous repair history, replacement parts and repeat-failure pattern
