Scope of this technical record
Use this record when an ACS800 service case involves AGDR gate-driver hardware, 2340 SHORT CIRC, repeated module failure or an output-stage repair intake.
Board identity and visual evidence must be collected only after the drive is safe. Do not treat this page as an instruction to energize driver circuitry on the bench.
ACS800 AGDR assembly evidence route
The record prevents ordering an assembly by series name alone.
AGDR evidence needs context
An AGDR assembly is not a generic card request. It must be tied to the installed ACS800 frame, output module, phase leg, connector route, failure timing and prior repair history. The same board family name is not enough to confirm compatibility or root cause.
The evidence record should also note contamination, heat marks, vibration, connector strain and any sign that the driver damage may be secondary to a failed IGBT or external output condition.
AGDR service intake
| Evidence | Needed for | Missing evidence risk |
|---|---|---|
| AGDR label/revision | Repair or donor-board match | Wrong assembly |
| Output module relationship | Driver-to-IGBT boundary | Unclear root cause |
| Fault timing and leg clue | Targeted investigation | Broad parts swapping |
| Previous repair outcome | Repeat-failure prevention | Another immediate failure |
What the record should conclude
The conclusion should be one of a small set: external output route, AGDR driver assessment, IGBT/module repair, combined driver/module repair, current-feedback/protection investigation, donor-unit compatibility review or modernization. If the case cannot be placed into one of those routes, more evidence is needed before a board decision.

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
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.
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.
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
